• Concrete mixing should not be carried out within 15m of a tree.

• It is essential that fires not be lit on site.

• Trees to be conserved will not be used as anchorages for equipment used for removing stumps, roots or other trees, or for any other purposes.

• Notice boards, telephone cables, or other services should not be attached to any part of a tree.

• Care should be exercised when using cranes or similar equipment near the spread of the canopy of a tree. All machinery operators are to have the appropriate operation tickets and qualifications as per the applicable governing body requirements.

• Trees to be felled that are adjacent to or that lie within a continuous canopy of trees to be retained should be removed with particular care. In some cases a tree may have to be removed in sections to avoid damage.

4.4.5 Tree Removal

Remove trees marked 'Existing Trees to be Removed' as shown on plan. Care shall be taken when removing existing trees not to damage any trees to be retained.

When excavating/ trenching around any significant roots a nominated, qualified Arborist shall be given prior warning and shall be present on site to supervise the removal or redirection of the roots. No root removal shall be carried out without the advice or supervision of the Arborist.

Where possible locally redirect services around roots, trunks or tree protection zones as opposed to removal.

4.4.8 Installation of pavement surfaces adjoining existing vegetation

This refers to all proposed hard pavement surfaces including but not limited to bitumen, paths, edging, concrete and stonework.

The installation of all pavement surfaces shall have minimal effect on all existing trees to be retained. All machine trenching and excavation shall be carried out with the location of tree roots and branches in mind and hand excavation shall be utilised around tree roots to minimise effects or damage.

When excavating around any significant roots the nominated project Arborist shall be given prior warning and shall be present on site to supervise the removal or redirection of the roots. No root removal shall be carried out without the advice or supervision of the Arborist.

Where pavement surfaces and or their respective excavations are projected to have an impact on existing tree roots, trunk and branches, the contractor shall look at alternative surfaces to ensure the protection of the tree and guarantee the long term healthy growth of the specimen. Where possible locally redirect services around roots/ trunks as opposed to removal.

4.5 ARBORICULTURAL WORK

4.5.1 Remedial Work to Existing Vegetation

10.12 PLANTING

10.12.1 Plant Material Quality Specification – Nursery Stock

All plants shall be true to scheduled nomenclature, well formed, hardened off and disease free nursery stock. They shall be container grown in potting soil with root system firmly established but with no large roots growing out of the container. No plant shall be pot bound.

All trees supplied shall comply with AS2303:2018 Tree stock for landscape use.

The condition of plant stock shall be such that future growth shall be strong and typical of the species. Stock that shows signs of latent conditions evident of defective nursery practices (such as ‘spiralling') shall be deemed unacceptable.

The Contractor shall allow for an independent Horticultural certification of all stock prior to delivery to site.

The certification shall confirm the following:

• stock is disease free and healthy;

• rootball has adequately grown into the container appropriate to the specified size;

• Stock shows no evidence of spirally, being pot bound, or other undesired outcomes of growth at the nursery.

The stock (especially trees) shall be of a standard that should an independent inspection be carried out at a minimum of 12 months from date of planting, the stock (all parts of the tree) would deemed to be typical of a



March 2019

healthy, thriving specimen. This does not include external factors, post planting of which the nursery would not have control over.

All plants shall be grown in accordance with Nursery Association standards and AS 2303:2018. Correct nursery/ growing practices shall help to ensure the long term health and viability of the plant stock on site after planting.

Trunk and Branch Requirements:

Ensure that trunks and branches are free of dieback, cavities, sunburn and secretions. Trunk and branches are to be evenly tapered and textured typical of the specie. Plant material is to be matured enough to support themselves without staking. Branches should be evenly distributed, exhibit a full well formed canopy that occupies a minimum 1/3 of the overall current height. Specimens are to be prepared for their intended purpose. For ex-ground stock where canopy modification is intended, provide details of how each specimen’s visual character will be at time of delivery.

Foliage Requirements:

Foliage shall be evenly distributed across the crown in proportion to the branching structure as well as be of a true colour typical of the specie, dense and of good size. Ensure foliage is free of deficiencies and burn. Plant material is to be ‘hardened’ to full sun and exposed conditions by the supplier to ensure successful plant establishment into the site environment. For ex-ground stock apply an anti-transpirant.

Size and Form Requirements:

At the time of the last plant stock review prior to site delivery, plant material is to conform with the specified minimum plant sizes in the Plant Schedule. Plants shall not exhibit signs of having been stressed at any stage during their development due to inadequate watering, excessive shade/sunlight, suffered physical damage or have restricted habit due to growth in nursery rows.

10.12.2 Plant Material Quality Specification – Ex-ground Stock

All ex-ground stock shall be root-pruned, allowing adequate time, appropriate to the species for preparation; site conditions and season shall also be considered. Root ball sizing as a general rule should be large enough to support the specimen without being dependent on the use of guying. This is not to say that guying is not permitted, but is discouraged as the primary support mechanism for the weight stabilizing of the specimen. The roots of advanced plant material should be sound and free from breaks, torn or bruised bark, crown gall and nematodes. Structural roots where cut are to be dressed with 3 coats of bituminous fungicidal paint. Root ball sizing is to minimize stock, canopy modification and recovery time for re-establishment into the new environment. The root ball is to be square with a flat base, straight vertical sides and well balanced to help find its natural centre of gravity for a vertical position once placed. Maintain in a moist state throughout the preparation process. Wrap in Hessian secured with steel bonds to ensure that the base remains intact. Do not provide stock, which have been established from incompatible soils to that of site.

10.12.3 Myrtle Rust All stock is to be checked for Myrtle Rust. Myrtle Rust is a serious fungal disease that affects plants within the Myrtaceae family (e.g. Lilly Pilly, Eucalyptus, Tea Tree and Bottle-brush species) for further information on Myrtle Rust refer regularly to the Department of Agriculture and Fisheries, and or BioSecurity Queensland’s website to ensure that the Contractor has the most recent advice on Myrtle Rust.

The Contractor is to ensure all tools, plant and clothing has been cleaned prior to coming onto site if they have been working within a known Myrtle Rust area.

In the instance that Myrtle Rust is either found on the imported plant stock or within the site itself, firstly contact the Superintendent and then contact Biosecurity Queensland on 13 25 23.



March 2019

10.12.4 Approval The Superintendent may elect to inspect planting stock prior to planting, and will notify the Landscape Subcontractor of this intent in writing. Inspection of planting stock by the Superintendent prior to planting does not constitute acceptance of the planting material, and the Superintendent may reject planting material if it fails to comply with specified requirements at any stage of the works. If it is deemed more convenient, inspection of the stock prior to delivery may be arranged at the nominated nursery. The Landscape Subcontractor is to coordinate these visits 2 (two) weeks prior to delivery to site. The Superintendent is under no obligation to inspect stock at the nursery.

The Superintendent has the right to reject any plants not meeting the requirements of the specification and schedule.

The approval of stock (either prior to delivery, prior to planting, on practical completion or at off-maintenance) by the Superintendent is based on the conformance of the stock with following performance criteria:

• specified size parameters (height, canopy spread, girth size),

• container size,

• general appearance and health of the plant. The Superintendent may select at their discretion, 1 no. specimen per species on which to examine the general condition of the root ball (by removing the container/ bag). This however is not deemed approval of stock with inherent/ latent defects (as a result of nursery practices) leading to the long term growth and health of the plants.

As set out in section 8.12.1, the Contractor shall allow for an independent Horticultural certification of all stock prior to delivery to site. This certification shall be forwarded to the Superintendent.

When species and/or sizes of plants are unavailable obtain instructions from the Superintendent before proceeding. No substitutions shall be made without the prior approval of the Superintendent.

10.12.5 Delivery & Storage

Programming of delivery of plant material is to be arranged between the Contractor and the nursery to minimise delays to the plant program and to minimise damage to plants during the transportation and unloading. The Contractor must satisfy themselves as to the quality of the plants before arranging delivery of them. Claims for loss because of supply of inferior material will not be accepted.

Inspect stock with the Superintendent and the Contract Supplier once the stock has arrived on site prior to unloading.

Do not store stock on site temporarily. Deliver plant material to the site on a day-to-day basis, and plant immediately after delivery.

Store plants so they of their containers will not be damaged. Water and maintain all plants as necessary. Provide all lifting equipment for stock delivered to site. Inspect stock with the Superintendent and the Contract Supplier once the stock has arrived on site prior to unloading.

Protection: Prevent plant stock from damage. Inspect all stock for disease and pests. Report on recovery success and give notice of site plant stock, which will not recover from relocation.

Replacement: Replace damaged or failed plants with plants of the same type and size.

10.12.6 Plant Schedules

Refer to the plant schedules attached.



March 2019

Plant numbers on drawings override numbers in the schedule. Contractor is to check and verify all plant numbers and inform Superintendent of any major inconsistencies between the schedules and the drawings.

10.12.7 Preparation

Excavate or fill areas as necessary allowing for depths of modified site soil and mulch. Remove and destroy any grass or weed growth present. If noxious weeds are found, such as nut grass, in the area to be cultivated and prepared, inform the Superintendent before proceeding.

Decompact existing ground to a minimum of 100mm. In areas of cut or where compaction of the subgrade has occurred deep rip sub-grade to minimum depth of 200mm.

Carry out any sub-surface drainage works as specified and/or shown on drawings.

Spread soil as specified to depths as shown in details ensuring minimum thickness shown on drawings after settlement.

As the ground is worked, all garden areas are to be raised or crowned in the centre to assist in soil drainage unless in a designated overland flow path.

Finished level of soil at paths to allow for settlement and for the placement of mulch or turf as specified.

10.12.8 Individual Plantings in Grassed Areas

Excavate planter pits as per details. Break up the base of the hole to a further depth of 100 mm, and loosen compacted sides of the hole to prevent confinement of root growth. Create seepage channel drain where subsoil is a hardpan nature to discharge subsurface water.

10.12.9 Ripline Planting

Rip the row and excavate a plant hole for each plant large enough to accept the root ball plus 0.1 m³ of backfilling with topsoil. Clear weeds and other vegetative material within 300 mm radius of the plants. If planting holes are excavated by mechanical means increase the hole size by 100 mm and loosen compacted sides to prevent confinement of root growth.

10.12.10 Locations

If it appears necessary to vary plant locations and spacing’s to avoid service lines, or to cover the area uniformly, or due to modifications to driveway locations, or due to striking rock, or for other reasons, give notice.

10.12.11 Planting Conditions

Do not plant in unsuitable weather conditions such as extreme heat, cold, wind or rain. In other than sandy soils, suspend excavation when the soil is wet, or during frost periods.

10.12.12 Watering

Thoroughly water the plants before planting, immediately after planting, and as required to maintain growth rates free of stress throughout the contract period. Hand water if irrigation system is not operational. The Landscape Subcontractor is to allow for temporary establishment watering methods of shrub areas such as watering trucks in the event of water being unavailable.

10.12.13 Fertilising

Fertiliser shall be an approved prolonged release type. Place around plant approximately 1/3 the depth of root ball, but no more than 250mm depth and approximately 50mm away from root tips. Place at time of planting

10.13 MULCHING Mulch

General: Provide mulch which is free of deleterious and extraneous matter such as soil, weeds and sticks.

Standard: To AS 4454.

10.13.1 Site Mulch (installed as directed by Landscape Architect)

In the instance that mulch can be sourced from site, it is the Contractors responsibility to check that the site mulch (sourced from site cut vegetation) has been ‘pasteurised’ prior to being used within the rehabilitation zones. Pasteurisation will significantly reduce the number of plant and animal pathogens as well as plant propagules (seed bank).

The following dot points are the minimum requirements to ensure the mulch has been pasteurised (based on AS4454-2012 – Composts, soil conditioners and mulches).

1. Designate a location on site that the mulch can be stored.

2. Site mulch stockpiles should not exceed 1.5-2 meters high; ensure access is available from all sides. The designated height is mainly for safety reasons and for the ease of turning the material.

3. Turn the outer material into the centre of the stockpile at a minimum of every three days, with the goal of the internal temperature reaching a minimum of 55˚C.

4. Turn the stockpile a minimum of three times (three separate events).

5. If the above process cannot be abided by, just ensure that the high temperature of 55˚C is reached while tilling the stock pile over a 2-3 week period.

6. Note: once the above process has been achieved, and if the site mulch stockpile is to be left for a prolonged period of time before being used. Ensure the mulch is at least turned on a 4-6 week basis, to keep the mulch viable.

Site Mulch Minimum requirements

• Site mulch to be free of deleterious and extraneous matter such as soil, turf, rocks and sticks.

• Site mulch to be double tub ground (preferable) and a maximum stick length of 150mm

• Material not permitted in mulch stock piles: weed species such as privet, camphor laurel, coral tree, poplar, willow, pine and lantana, other noxious weeds.

10.13.2 Imported Organic Mulch Types

• Imported Organic Mulch: Forest Blend Mulch (maximum stick length 50mm).

Material not permitted: Leaf and plant matter from any other species (especially weed species such as privet, camphor laurel, coral tree, poplar, willow, pine and other noxious weeds).



March 2019

10.13.3 Placing Mulch

General: Place mulch to the required depth, clear of plant stems. Spread mulch so that after settling it is smooth and evenly graded between design surface levels sloped towards the base of plant stems in plantation beds, and not closer to the stem than 50 mm in the case of gravel mulches.

Extent: To surrounds of plants planted in riplines and grass areas, provide mulch to 1000 mm diameter. Mulch areas to Ex-ground trees to be 1800 diameter.

Spread mulch to the following depths:

Feature Planting Areas: As per Materials and Finishes Schedule

Rehabilitation Planting Areas: As per Materials and Finishes Schedule

Mulch Only Areas: As per Materials and Finishes Schedule

10.15.2 Ties

Ties shall be 50mm wide hessian webbing or 25mm wide heavy-duty polythene strips. (Plastic coated ties are not acceptable). Fix ties in a figure of eight pattern and staple to stake with galvanised wire staples. In cases where strong ties are required past the maintenance period, 50mm UV stabilised woven polypropylene ties should be used.

10.16 GUYING Requirement

While guying is not encouraged for ex-ground planting in natural ground (if required, use discretion as to the appropriateness of its application), the Landscape Subcontractor is to be responsible for the stability of the tree for the period of establishment. Provide temporary support where necessary to trees (over 3m tall), root balls or stakes using galvanized steel cables. Galvanised cables to pass through reinforced rubber or hose when in contact with the tree. Any damage may result in tree replacement. Ensure enough slack is allowed in

10.17.5 Operations

Remove dead and decayed wood or limbs that have been broken. Make neat cuts into live wood, which allows water to run off. If the trees show signs of deterioration after the work has been done, carry out a program of feeding or soil amelioration such as soil aeration, irrigation or incorporation of organic material. Continue this program until the end of the planting establishment period.

10.17.6 Precautions

Avoid damage to trees being treated or to nearby trees and surroundings. Do not use trees as anchors for winching operations or bracing. Provide bracing as necessary before cutting to prevent uncontrolled breakages and damage to surroundings.

10.17.7 Dressing

Prevent incursion of rot or disease after cutting.

10.17.8 Root Pruning

Do not unduly disturb the root system of plant stock that would threaten the stability of the specimen from supporting itself in an upright position.

10.17.9 Plant Waste

Where practical, mulch all material taken from pruned plant stock for re-use on garden beds. (Incorporate into imported mulch to diffuse impact). Otherwise all waste is to be removed from site. No waste from declared weed species and those highlighted by the local authority are to be used as mulch. Remove and dispose of this waste from site.

APPENDIX B Dulux Render Finish

AUDA1582Dulux AcraTex Green Render Sealer

Part A 19420802

Product Overview

DULUX AcraTex Green Render Sealer is a Water Based primer/ sealer designed specifically for the preparation of fresh "green" masonry surfaces to

minimise unsightly white salts or "efflorescence" migrating through the applied coating system and speed project coating schedules by reducing the traditional

concrete/render "Alkalinity passivation" wait period.

AcraTex Green Render Sealer deigned to reduce the normal site mixed cement render "28 day / Bagged Render 7-10 days wait cycle"

- Green Render Sealer can be applied over 2 day old cement render providing moisture content has stabilised.

Features And Benefits

Superior water and alkali resistance

Seals and Primes masonry surfaces

Penetrating binder

Water based,

Fast track coating

Ensures good, uniform adhesion of topcoat

Consolidates masonry surfaces

Low VOC

Reduces Scaffolding Hire costs

Uses And Typical Specifications

Uses Green Render Sealer can be used over all masonry surfaces to provide excellent system adhesion and integrity with long term durability.

The primer forms a barrier over alkali substrates limiting the reaction with atmospheric Carbon Dioxide thus reducing the formation of unsightly

white deposits or "efflorescence" on the surface typically associated with coating of highly alkaline "Fresh" masonry.

The primer allows for reduced substrate curing time prior to coating, thus fast tracking project work and reducing overall project costs and

construction time.

Premium High Build Levelling and Acrylic Texture Finishing System for application over new & uncoated aged Brick

work & Block work.

Incorporating:

AcraTex RenderWall as a Cementitious surface leveling base coat render used to level out brick work & block work

- Green Render Sealer (GRS) can be applied over 2 day old cement render providing moisture content has stabilised.

AcraTex 951 Coventry Coarse is a decorative, low build protective coating displaying excellent resistance to

weathering and atmospheric chemicals. The finish will resemble that of a coarse granual render which is sponge

floated.

AcraTex AcraSkin, weather-proofing topcoat, applied by conventional NAP roller to provide a paint like appearance

with excellent water impermeability, resistance to mould and mildew, high build crack bridging performance for long

term protection of cement render substrates.

Cement Render is hard and brittle due to the inherent nature of cement. Cement render will develop shrinkage cracks on

aging and continues to harden

(Hydration process) over its life cycle, further increasing risk of cracking. - Dulux does not recommend low build

(conventional) paint finishes over cement render. Not for immersion.

Precautions And Limitations

DO NOT TINT.

Green Render Sealer's ability to restrict the formation and transition of efflorescence relays on the formation of a continuous "barrier" layer, thus requiring

specific attention through the application process to ensuring adequate and consistent cover.

This product data sheets is to be read in conjunction with DULUX specification.

Ensure that you have adequate tinted stock to complete the job in one application. All material must be thoroughly cross-mix to ensure tint uniformity.

It is recommended to hold a volume of finish material for future maintenance touch-ups

Practical spreading rates will vary from quoted theoretical figures depending on substrate porosity, surface roughness, overspray losses, application

methods and environmental conditions (e.g. wind).

All preparation and painting must conform to AS2311: The Painting of Buildings

At Commencement of coating system application, to the substrate it shall be deemed that the Applicator has certified that the surface which the coating/s is to

be applied to, is fit to receive the specified coating(s) system.

Do not apply paint if Relative Humidity is above 85% or temperature is within 3°C of Dew Point.Do not apply if the surface temperature is greater than 40°C or below 10°C, or likely to fall below 10°C during the application or drying period.Dry times apply to a single coat at recommended spread rate and at 25°C and 50% Relative Humidity Allow longer times under cool, moist, or still conditions and or when applied at high film builds.

Protect from dew, rain and frost for 48 hours when apply at the recommended spread rate.

Avoid application in hot, windy conditions or on hot surfaces cool the surface by hosing with water and paint the cool damp surface.

Application techniques should be adjusted to achieve the recommended DFT and finishing standard.

To avoid "Picture Framing" of texture topcoats "wet on wet" cutting in & coating technique is recommended or apply multiple coats thinning the first coat.

When using Bright Reds, Oranges, Blues and Yellows or where very light (or dark) colours are applied over highly contrasting colours an extra coat maybe

required.

The coastal area is considered a marine environment and as such salt potentially can shorten the life of the coating systems. Care needs to be taken to wash

down all areas twice. Once to remove surface contaminants, and raise salts to the surface and then secondly to remove these salts. Due to the locality,

weather conditions and lag time between applications of the coating system it may require the need to wash again, between coats.

When the Applicator is preparing the site sample for approval he should advise the Project Superintendent if the substrate condition is not of sufficient

standard to produce the specified finish.

Where possible avoid dark colours - these will give raise to much higher surface temperature that may cause addition thermal stress and cooling demand to

the building envelope and/ or require extra engineering considerations (greater building costs).

Consult Dulux on the potential to use InfraCOOL Heat Reflective Coatings.

A DULUX warranty can be provided on request, when the FULL AcraTex system including a membrane topcoat/s is applied by a DULUX AcraTex trained

applicator, according to specification, & at the specified spreading rates, & to the surface preparation details described in the DULUX AcraTex Specification

Manual.

The dynamics of the substrate is outside the control of Dulux Australia and as such joint deformation or cracking is excluded from warranty terms.

Colour change is a natural part of a coating weathering and is excluded from warranty terms

Refer warranty document for full terms and conditions.

CEMENT RENDERS PRODUCE FINE CRACKS DURING DRYING AND CONTINUE TO CRACK & MOVE WITH VARIATIONS IN TEMPERATURE.

FOR ENHANCED PERFORMANCE USE A HIGH BUILD ELASTOMERIC (FLEXIBLE) COATING.

DULUX RECOMMENDS THE USE OF DULUX ACRASHIELD ADVANCE.

Fungi and Algae can exist on virtually any surface (even glass) provided the right conditions for growth are met.

Visible growth on painted surfaces is typically caused by contaminants present together with the presence of high enough levels of moisture to support

growth. Agents in paints become ineffective where they cannot “touch” the growth source (eg where growth emanates from deposits on the film). Additionally the active agents are “consumed” in the process such that protection is time limited where conditions support ongoing growth performance isgreatly improved with the inclusion of a membrane Top coat like Dulux AcraTex AcraShield Advance, Elastomeric 201 or AcraSkin.

The exterior texture coatings should be cleaned on a regular basis. This will help maintain your overall aesthetic appearance and preserve your AcraTex

Texture coating system. Cleaning once every year will remove light soil as well as grime and airborne pollutants refer Dulux AcraTex Care & Maintenance

Typical

SystemsTypical System Typical Minimum Specification Rendered Masonry Substrates

Preparation Guide PBK019 - BRICK / BLOCKWORK AND MASONRY

ASSESS SUITABILITY

Concrete, mortar and cement based products need to be fully cured for at least 28 days before painting.

REMOVE POWDER LAYERS & EFFLORESCENCE

Remove any powdery layers, laitance or efflorescence by detergent cleaning, wire brushing, water blasting or a

suitable chemical treatment.

CLEAN

Clean the surface thoroughly by water blasting or detergent cleaning, where a commercial cleaner is added to hot or

cold water and surface is washed / scrubbed thoroughly with a stiff bristle broom and then rinsed clean with fresh

water. This may need to be repeated on extremely dirty surfaces to ensure removal of efflorescence or other poorly

bonded surface material. Ensure that the surface is dry, clean and free from dust.

RENDERING OF NEW BRICK/ BLOCKWORK & MASONRY

(WHERE SPECIFIED TO LEVEL THE BRICK/MORTAR PATTERN)

: Trowel apply a basecoat of Dulux AcraTex Renderwall over entire substrate at approximately 6mm to 8mm in

thickness until flush.

A Screed or darby may be used to level the renderwall prior to floating with a plastic or wooden float.Renderwall can

be applied at a thickness as low as 4mm ( with addition of Acrabond a 100% acrylic resin at 250ml per mix) or above

12mm ( in two successive coats) relative to the degree of cover required, if desired 150grams Alkali mesh maybe

embedded into the base coat.

COATING CONSIDERATIONS FOR NEW RENDERS

All renders produce surface cracking whilst drying & curing which continue to expand & contract during daily

temperature fluctuations allowing water ingress and causing potential discolouration and coating failure.

The specified coating needs to accommodate the renders thermal dynamics, protect from atmospheric pollutants, salt

air, water ingress, alkali attack, dirt accumulation and carbon dioxide.

Recommendation is a High Build Acra-Tex Elastomeric Coating System.

Dark colours increase expansion/contraction of a substrate due to heat absorbed and should be avoided where

possible or extra design relief should be added to building's design.

The coastal area is considered a marine environment and as such salt potentially can shorten the life of the coating

systems. Care needs to be taken to wash down all areas twice. Once to remove surface contaminants, and raise salts

to the surface and then secondly to remove these salts.

Due to the locality, Weather conditions and lag time between applications of the coating system it may require the need

to wash again, between coats.

Do not apply paint if the temperature is below 10°C or likely to fall below 10°C during the drying period.This specification must be read in conjunction with the appropriate technical data sheets.

When using this specification, the Applicator shall maintain records in accordance with AS3894 Parts 10, 11 and 12

and others as required by the Project Manager. These records shall be made available for inspection at any time by the


Project Manager or authorised representative and submitted to the Principal Contractor upon completion of work.

CEMENT RENDERS PRODUCE FINE CRACKS DURING DRYING AND CONTINUE TO CRACK & MOVE WITH VARIATIONS IN

TEMPERATURE.

FOR ENHANCED PERFORMANCE USE A HIGH BUILD ELASTOMERIC (FLEXIBLE) COATING. DULUX RECOMMENDS THE

USE OF DULUX ACRASHIELD 955 .

At Commencement of coating system application to the substrate it shall be deemed that the Applicator has certified that

the surface which it is to be applied to is fit receive this specified coatings system.

When the Applicator is preparing the site sample for approval he should advise the Project Superintendent if the

substrate condition is not of sufficient standard to produce the specified finish.

Where a site mixed render or pre-mixed bagged render substrate is deemed friable & powdery, dried, cured & aged for

28 days or more AcraPrime water Based Primer is to be substituted with the deep penetrating AcraPrime Solvent Based

sealer for maximum surface consolidation

Where sound site mixed render or pre-mixed bagged render substrate have been not allowed to dry, cure & or aged for

28 days or more Green Render Sealer should be substituted with AcraPrime water Based Primer.

Where bright reds and yellows or very light colours are applied over highly contrasting colours an extra top coat maybe

also be required.

Ensure adequate batch tint lots to achieve coverage over single elevations to ensure colour consistency. It is

recommended to hold a volume of finish material for future maintenance touch-ups



Do not thin or apply over damp substrate (except where specified to AAC).

Do not use DULUX AcraTex AcraPrime water Based under DULUX AcraTex RenderWall.

AcraPrime 501/1 is suitable for well clean, sound masonry that has cured for 28 days or longer. Where the substrate is less than 28 days and greater than 3

days curing Green Render Sealer is recommended.

Where the substrate is friable or powdery, substitute AcraPrime Deep Penetrating Solvent based sealer in lue of AcraPrime Water based.

or

Use AcraPrime Deep Penetrating Solvent based sealer if concrete is high in MPA value and there are concerns around adhesion to hard dense and /or

smooth concrete

To ensure colour uniformity and for optimum performance, Dulux recommend a full coating system including a MEMBRANE top coat.

For ALL systems the Texture &/or Base Coat should be tinted in accordance with AcraTex Tint Guide to the specified top coat colour

Preparation

All surfaces must be cured, clean, sound and free of all contaminants such as form oils, release agents & mortar splashes. Surface

imperfections, misalignments and protrusions must be levelled & patched & completely flush to surrounding surfaces. Metal, tie wire, etc

on surface must be removed or treated against corrosion.

Substrate Moisture Content:

Moisture Content of dense concrete prior to coating should be less than 8% measured to a depth of at least 25mm and not be subject to

re-wetting from latent sub-surface moisture or external sources.

Typically this requires 8-12 weeks drying of dense precast or cast insitu concrete.

Accurate measurement of concrete moisture content requires specialist equipment (typically involving drilling and insertion of probes

embedded in an electrically conductive gel)

Indicative surface spot measurement using a device with fine surface needle probes (generally referred to as "Equivalent Wood Moisture

or EWM" ) is less reliable in discerning sub surface moisture and may produce variable results dependent on the density of the masonry

under test and the presence of any substrate salts which can affect conductivity. Some units can operate in search or survey mode

providing indications of potential sub surface areas of concern.

Typically, "EWM" content prior to coating should be less than 12% and it is recommended that area review includes sub surface surveying

to identify potential areas of concern.

Alternatively a practical test to confirm "concrete safe to paint" involves taping (sealing all edges) of a 1m x 1m clear plastic sheet the

concrete surface and leaving for 24 hours. Darkening of the concrete under the film or condensation on the underside of the film indicates

the presence of excessive moisture

SURFACTANT LEACHING FROM EXTERIOR WATER-BASED COATINGS

Occasionally amber, clear or white spots/streaks are seen on a newly painted surface within the first few weeks after application. They usually appear after

light rain or overnight dew and generally located in sheltered areas or areas with limited sun exposure. Under normal conditions surfactant contained in the

tinted paint colour is slowly leached to the surface and washed away by rain leaving no trace and is a normal part of drying of any exterior water-based

paint. Under certain atmospheric conditions and these surfactants leach or migrate to the paint surface, is concentrated forms and leaves clear or white

deposits upon drying. These conditions include cool or humid weather or painting cold substrate and in most cases these marks on the wall surfaces are

more noticeable on dark colours, such as browns or dark greens, etc..

The clear/white surfactants that have migrated to the wall surface areas will cause no down grading nor performance changes or long term durability

concerns of the paint films integrity and unfortunately have become an appearance issue instead.

They easily removed from the paint film within a week or so of their appearance by washing with warm water & commercial grade detergent or via Nifti or

Spray'n'Wipe followed by rinsing with fresh clean water.

Under severe conditions they may reappear once or twice until all the surfactant has been removed. It will be less noticeable each time, and can be removed

in the same manner as before. Refer http://www.dulux.com.au/pdf/tech-advice/DLX_TECH_Leaching.pdf

APPENDIX C Cutex Timber Stain and Oil Finish

cutek.com.au

FACTSHEET No 2 Cutek Extreme Oil

When other timber coatings fail professionals turn to Cutek

Cutek Extreme Advanced Timber and Engineered Wood Protection

When you need a professional grade finish choose Cutek Extreme.

This high performing wood protection oil has been formulated by

experts to control moisture and minimise warping, cupping and splitting

- making your project last longer.

It resists water from the inside out, so it’s perfect for outdoor applications

on natural and thermally modified wood and it is strong enough to stand

up to Australia’s most challenging tropical climates. Cutek Extreme is

the only product in our range that’s suitable for use on bamboo and

engineered bamboo products.

Cutek Extreme comes as a clear oil which fades in the sun to a natural

silver patina but at slower rate that Cutek CD50. It may also be mixed

with any of our 10 colourtones to enhance and maintain the freshly oiled

natural look of your timber.

Cutek Extreme is NOT suitable for use on acetylated wood.

• Best for challenging environments – clear silvers at a slower rate than

CD50 or may be used colourtoned to retain the freshly oiled look

• Protects from the effects of moisture – minimises warping, cupping

and splitting

• The right choice for most engineered wood products.

Understanding colourtonesIt’s important to understand that CUTEK is a unique penetrating oil system designed to enhance the natural colour and

grain of wood. CUTEK is sold as a clear oil which can be used to protect the wood from moisture and moisture related

movement such as cupping, warping and splitting. Using just the clear oil will protect the wood, providing stability and

structural integrity while allowing it to naturally lighten to produce a silver weathered patina over time. The soft natural

cutek.com.au

lightening and silvering of the wood represents a low care option and is becoming an increasingly popular way to leave

wood in weather exposed settings.

Wood projects using clear CUTEK oil that have silvered can easily be returned back to the wood’s original colour using

ProClean and high pressure washing followed by further applications of CUTEK clear oil.

However, if you desire to maintain the original colour of the wood then you need to purchase a Colourtone suited to your selected wood which will further enhance the natural colour and grain and help to maintain its “natural” colour over a longer period of time.

What to expect when using colourtone

Most wood care products on the market leave a build up of material on the surface of the wood. In the short term this

provides more colour, but in the long term the finish can be prone to peeling and flaking, which requires time and money

to repair.

The Cutek system is unique as it will fade over time rather than peel or flake. The initial Cutek Colourtone build on new

smooth wood projects only offers subtle amounts of pigment that enhance the wood. Timber that’s exposed fully to

the weather will lighten faster as the wood acclimatises over the first six months. A follow up application after this initial

weathering period will provide much greater Colourtone build as the wood becomes rougher and more open.

How to increase colour build on new wood

New wood is milled smooth and often has a mill glaze which will greatly restrict the initial colour build. Better results can be

achieved by creating a rougher surface and preparing the wood using Cutek Proclean in combination with a high pressure

washer. Sanding the new wood to 80 grit will give even better results as it removes mill glaze and creates a much rougher

surface which will enable higher colour build. Note The rougher the surface of the wood, the greater the colour build

and durability. Rough sawn or heavy brushed wood profiles will take more oil and colour so much bolder colour contrast

can be achieved. The amount of mill glaze if any that is present on any job can vary significantly depending on species

density, and machining method used. Note Sanded surfaces should be vacuumed or washed thoroughly to remove all

loose wood and dust.

Before you apply

Surface preparation is essentialIn order for Cutek Extreme to function properly it’s essential that it diffuses deeply into the timber. Anything that might

prevent penetration such as an existing coating, retained moisture, or not leaving sufficient time between coats must be

avoided or corrected before applying.

Preparation may involve thorough sanding or stripping to completely remove any previous film forming coating.

If stripping is required, we recommend using Cutek CD33 Naked and Cutek Proclean to prepare the surface

for Cutek oils.

Before using Cutek Extreme, it is vital to ensure the wood is clean, dry (moisture content less than 17%) and has no

existing paint, oil or stain.

Always remember that unless you want a clear finish that will lighten/silver off in a few months, it is important to mix a

Cutek Colourtone into the oil before use.

Make sure you prepare your timber before applying Cutek Extreme in order to get the best results.

cutek.com.au

How to apply

New Wood

Ensure that timber to be coated is clean and dry. Cutek Extreme can be used on treated timber, however wood with mill

glaze, or pre-treated with wax and polymer processes such as LOSP may require cleaning first with Cutek Proclean.

Old, or Previously Coated Wood

Old, dirty, stained or weathered timber should be prepared by first applying Cutek Proclean restoration agent, then power

rinsing with a high-pressure washer set to under 750 p.s.i. (50 bar), with a fan jet pattern to avoid damage to the wood fibre.

Once the timber is thoroughly dry, apply two coats of Cutek Extreme.

Wood previously coated with a film forming product such as stains, linseed oil, paint, polyurethane, etc., must first be

restored with Cutek CD33 Naked paint stripper and Cutek Proclean prior to the application of Cutek Extreme. This

process can be complex, so view the videos on this website for more information.

The results achieved from restoration are dramatic and rewarding – the original natural colour and beauty of wood

can be restored.

Application Technique

Before you get started

Before you begin, note the hazards and precautions on our website and the can labelling, and ensure that you use the

correct safety equipment as detailed in the Safety Data Sheet.

Step by step application process

Avoid contact with plants, shrubs, trees and waterways. For best results, one coat of Cutek Extreme should be applied

to all faces of the wood prior to installing, with a second coat applied to the top surface once the first coat is

completely dry. Penetration time varies significantly, depending on species, temperature, porosity, and moisture content of

the wood. Thicker sections such as post, beams and logs will require additional coats, as Cutek Extreme has a cumulative

effect in the wood.

Apply each coat evenly with brush, paintpad or roller. When using Cutek Colourtone it is essential that the container

holding the oil be stirred frequently both before and during use. Two or three thin coats on finished wood and hardwoods

are better that one or two thick coats.

Wood must feel completely dry and non-greasy before application of the second coat.

Cleanup

Equipment may be cleaned with soap and water or turps. Oily rags and other oily materials may cause combustion fires.

Immediately after use you MUST (1) spread out all oily materials outside to dry, by flattening them out to their full size in

an airy spot at temperatures above 4 degrees Celsius, or (2) Wash them thoroughly with water and detergent and rinse.

Remove all oil from all clothes, tools, rags and any other materials contacted during use or as a result of an accidental spill.

All wash water is to be disposed of properly.

cutek.com.au

Coverage

These figures represent typical averages for common decking and cladding timbers such as Western Red Cedar, Pine,

Spotted Gum, Jarrah, Ironbark, Ipe, Tiger deck, Cumaru and other Exotics, Thermal wood etc.

New hardwoods dressed 10–20m2/litre (400–800sq feet/gallon)

Old restored timber dressed 7–9m2/litre (300–400sq feet/gallon)

New timber rough sawn 7–9m2/litre (300–400sq feet/gallon)

Old restored timber rough sawn 4–7m2/litre (180–300sq feet/gallon)

Shingles and shakes 2–5m2/litre (84–212sq feet/gallon)

MaintenanceCutek Extreme will gradually fade over time rather than peel, split or crack, so the rejuvenation of timber coated with

Cutek Extreme is a simple fast and cost-effective process.

Cutek Extreme should be reapplied when the wood is no longer beading water, or as frequently as necessary to retain the

natural beauty and colour of the wood. Clear Cutek Extreme coated timbers require maintenance less frequently than

colourtoned Cutek Extreme coated timbers.

Recoat time varies widely according to many factors including the age and porosity of the wood, species, situation and

exposure to the weather. Typically, horizontal exterior smooth surfaces such as pool decks and handrails may require

coating every 6 months to two years, while vertical rough sawn cladding may require maintenance less frequently.

cutek.com.au

FACTSHEET No 8 How to maintain Cutek


Surfaces that have been previously coated with Cutek oils that have faded, or started to “grey off” in the sun are easily

and quickly restored to their original appearance without the need for any sanding and stripping, by treatment with

Cutek QuickClean or Cutek Proclean, and the application of one or two further coats of a Cutek wood protection oil.

Cutek oils must be reapplied as frequently as necessary to retain the natural beauty and colour of the timber.

How to maintain Cutek oiled timber - step by step

1. Clean the timbers – Apply cleaner

If the timber is only dirty and faded, Cutek QuickClean may be all that you need to prepare the surface for another

coat of a Cutek oil. Cutek QuickClean is designed as a cost effective, biodegradable cleaner for the restoration of

uncoated, dirty and weathered timber. Cutek QuickClean is less powerful than Cutek Proclean, however it is less

hazardous, and will not damage substrates or vegetation adjacent to the timber surface being restored, eliminating

the need for containment or masking. If your timber is quite weathered and stained, better results will be obtained by

using Cutek Proclean.

Apply Cutek QuickClean liberally to the timber substrate with brush, roller, or garden sprayer. Let Cutek QuickClean do

most of the work by letting it dwell on the surface for 10 – 20 minutes, or such time as deemed to be necessary by the

test procedure. It may be necessary to scrub stubborn stains moderately with a stiff fibre brush.

2. Clean the timbers and remove the cleaner

Once Cutek QuickClean has cleaned the timber, it must be power water rinsed (hot water works best) off. For best

results wash off with high-pressure water at approximately 750 p.s.i. pressure. Clean from the lowest point and work

upwards methodically. ALWAYS clean off with a water jet that produces a “putty knife” shaped fan that is 40–50mm

wide about 100mm out from jet. Adopt a continuous “mowing action” working with power water fan-jet 100mm from

the face of the substrate. DO NOT use “turbojets” on timber. CAUTION must be used when cleaning soft timber to

reduce the pressure and avoid damaging the sapwood. The longer that Cutek QuickClean is left on the substrate,

the greater the rinse time required.

IMPORTANT

If the deck has been previously coated with another oil, other than Cutek, the timbers will

need to be stripped back to bare as most other oils on the market have a film-forming surface

polymer which forms a barrier which will inhibit the penetration of Cutek oils. Please refer to the

Factsheet No7.

cutek.com.au

3. Recoating with Cutek oil

Following the cleaning of the timber with Cutek Quickclean or Proclean, it is important to complete the maintenance

process by coating the timber with an appropriate Cutek wood protection oil, following the procedure detailed in the

relevant factsheet.

CAUTION must be used when cleaning soft and hard timbers - reduce or increase pressure by allowing the fan to

get closer or further away from the substrate. Additionally, certain types of wood surfaces may leave a raised grain,

these area can be sanded once dried. If you only have a low pressure, low flow pressure cleaner, a turbo head can

be used with caution.

IMPORTANT

Cutek oils designed to gradually fade over time rather than peel off, split or crack as is the case

with many conventional film forming coatings. For this reason, the rejuvenation and maintenance

of Cutek coated surfaces is a simple, fast, and cost effective process. Recoat time varies widely

according to many factors including the age and porosity of the timber, species, situation, and

exposure to the weather so we are unable to offer any specific performance warranties.

Typically, horizontal exterior smooth surfaces exposed to full weather such as pool decks and

handrails may require recoating every 6 months to 2 years, while vertical rough-sawn cladding

may require maintenance less frequently.

Cutek Colourtones Advanced Timber and Engineered Wood Colour System

We make preserving the beautiful, natural look of timber easy.

All Cutek oils are sold clear, which allows the wood to age gracefully into

a beautiful silver patina on exposure to sunlight. However, if you’d like to

retain the natural freshly oiled colour of the timber you’re working with

you can simply add a colourtone to the clear oil. Choose one of our 10

colourtones which have been specifically developed to closely match

many popular wood species.

For best results, select a colourtone that stays close to the natural shade

of the timber species being coated.

Autumntone

Greymist

Chestnut

Goldtone

Rustic Gold

Black Ash

Burnt Red

New Bronzetone

Walnut

Sela Brown

Understanding colourtonesIt’s important to understand that CUTEK is a unique penetrating oil system designed to enhance the natural colour and

grain of wood. CUTEK is sold as a clear oil which can be used to protect the wood from moisture and moisture related

movement such as cupping, warping and splitting. Using just the clear oil will protect the wood, providing stability and

structural integrity while allowing it to naturally lighten to produce a silver weathered patina over time. The soft natural

lightening and silvering of the wood represents a low care option and is becoming an increasingly popular way to leave

wood in weather exposed settings.

Wood projects using clear CUTEK oil that have silvered can easily be returned back to the wood’s original colour using

ProClean and high pressure washing followed by further applications of CUTEK clear oil.

However, if you desire to maintain the original colour of the wood then you need to purchase a Colourtone suited to your selected wood which will further enhance the natural colour and grain and help to maintain its “natural” colour over a longer period of time.

What to expect when using colourtone

Most wood care products on the market leave a build up of material on the surface of the wood. In the short term

this provides more colour, but in the long term the finish can be prone to peeling and flaking, which requires time and

money to repair.

cutek.com.au

The Cutek system is unique as it will fade over time rather than peel or flake. The initial Cutek Colourtone build on new

smooth wood projects only offers subtle amounts of pigment that enhance the wood. Timber that’s exposed fully to

the weather will lighten faster as the wood acclimatises over the first six months. A follow up application after this initial

weathering period will provide much greater Colourtone build as the wood becomes rougher and more open.

How to increase colour build on new wood

New wood is milled smooth and often has a mill glaze which will greatly restrict the initial colour build. Better results

can be achieved by creating a rougher surface and preparing the wood using Cutek Proclean in combination with a

high pressure washer. Sanding the new wood to 80 grit will give even better results as it removes mill glaze and creates

a much rougher surface which will enable higher colour build. Note…The rougher the surface of the wood, the greater

the colour build and durability. Rough sawn or heavy brushed wood profiles will take more oil and colour so much

bolder colour contrast can be achieved. The amount of mill glaze if any that is present on any job can vary significantly

depending on species density, and machining method used. Note, sanded surfaces should be vacuumed or washed

thoroughly to remove all loose wood and dust.

Selecting Colourtones

Our Colourtone system is designed to enhance the wood colour and grain you select. With this in mind, you

need to think about your original wood choice and the colour it most represents. Is it light to Golden, Brown,

Red or a combination? Here are a few common examples to help you understand.

Black Butt and Silver Top Ash… Light tones so Rustic Gold is a good choice.

Spotted Gum…Light creamy to brown and greys. Rustic Gold and Sela Brown will all look similar on new smooth wood.

Merbau and Red Iron Bark…red to brown tone so Autumn Tone, New Bronzetone, Burnt Red and Chestnut will all look

very similar on smooth wood.

Forest Reds and Jarrah…Red tones. Autumn Tone, New Bronzetone and Burnt Red are all close options and will look

similar on smooth wood.

Changing the original colour of any wood

For horizontal walk on surfaces such as decking, we recommend you select a Colourtone that is the closest match to

the wood you have selected, rather than attempt to change the colour. You can talk to any of our stockists for advice.

For cladding and screening, a much higher build of colour can be achieved which can completely change the original

tone of the wood. Even very light wood coloured species can become an almost solid Black, Grey, Red, Brown or Gold

if the wood surface is suitably rough and more coats or a higher pigment loading has been added.

In some circumstances you can double your Colourtone to achieve bolder effects on rough or brushed wood. We

advise that you contact us to discuss this option in more detail as we want to ensure you have the best information

possible.

Applying colourtonesOne colourtone size can be used in all pack sizes as follows:

• 1 x 250 ml Colourtone pot is required for a 5 litre can of CUTEK oil.

• 2 x 250 ml Coloutone pots per 10 litre can of CUTEK oil.

• 4 x 250 ml Colourtone pots per 20 litre can of CUTEK oil

Stir and mix the Colourtone well before adding into the clear oil. Continue to stir well with a flat stirrer, lifting from the

bottom, for about 2 minutes before use and give a quick stir about every 15 minutes during use to ensure even results.

cutek.com.au

For best results, one coat of clear CUTEK oil should be applied to all faces of the wood prior to installing, with a second

and third coat of colourtoned Cutek oil applied to the top surface once the first coat is completely dry. Two or three thin

coats on finished wood and hardwoods are better than one or two thick coats. CUTEK oils will take longer to absorb/

penetrate into dense hardwoods so thin coats are best so as to avoid delayed drying of the oil.

MaintenanceColourtoned Cutek oil will lighten/fade faster in full weather exposed areas whereas wood in protected areas will retain

colour with minimal maintenance over time.

Cutek is designed to gradually fade over time rather than peel, split or crack. Rejuvenation of faded timbers coated with

Cutek oils is a simple, fast and cost-effective process.

Clear or colourtoned CUTEK oil should be reapplied as frequently as necessary to retain the natural beauty and colour

of the wood. Assessment of this is subjective and it is important to realise that colour durability varies widely according

to many factors including the age and porosity of the wood, species, situation, exposure to the weather and how rough

the wood surface is.

Typically, horizontal exterior smooth surfaces exposed to full weather such as pool decks and handrails will require

re-coating more frequently (initially after 6 months, then annually) than vertical rough-sawn cladding (typically every

2-5 years).

Substrate And Substrate Preparation

Substrate

Notes:

SUBSTRATE DESCRIPTION

NEW TIMBER

New timber items should be delivered in a clean dry condition, just prior to installation. The timber should be inspected for physical defects,

such as splinters, cracks, woolly grain, machine marks, and knot holes and also for other defects such as sap and tannin stains, and resin

exudation from knots. Examine surfaces for wax or preservatives. Moisture content should be close to equilibrium moisture content, usually

10-17% for satisfactory staining or coating. Timber should stored out of the weather before painting. Timber left exposed to the weather for

as little as one month prior to painting will suffer from reduced paint adhesion and durability.

AGED TIMBER

Old timber surfaces should be inspected for dry rot, mould or fungus, excessive water content, grey and weathered timber, grain cracking,

resins, stains, old unsound paint, dirt and any surface contamination. These defects should be rectified prior to painting.

TANNIN RICH TIMBER

Tannins are water-soluble extractives present in some timbers such as meranti, merbau, kwila, western red cedar and tallowwood. These

tannins are leached out by water or moisture and can cause staining of surrounding areas. They are seen as dark coloured stains either

under or within a coating.

Tannin staining is most obvious in light coloured coatings, such as whites. Darker and wood-toned colours hide the tannin stains best. When

using light colours on tannin rich timbers, an appropriate primer should be used to seal the tannins in the wood. These products are

manufactured as smooth sheets consisting of wood fibres bound with either natural lignin or a small percentage of phenolic resin.

Hardboard is widely used as interior panelling but is vulnerable to moisture and therefore not suitable for exterior exposure or in high

condensation conditions. Repairing damaged hardboard is not generally practicable and it is advisable to completely replace any damaged

sections. These products are manufactured from timber fibre bound with thermosetting phenol formaldehyde resin. They contain wax which

may inhibit the drying of solvent based alkyd enamels and tannins which may bleed through water based coatings. As manufactured the

smooth surfaces provide an ideal surface for finishing but machined edges are more porous and may show fibre raising when primed.

Substrate

Preparation

Notes:

ASSESS SUITABILITY Ensure the wood is thoroughly clean and dry before commencing. If there is any doubt, measure moisture content

which must be between 10-17% before staining or finishing can commence.

REMOVE SURFACE CONTAMINANTS Examine the surface for the presence of sap, grease, oil, wax, tannin, building marks, or other

contaminants. Scrape off and remove residual contaminants by solvent cleaning. Use scraper to remove dirt and mortar splashes. Any

greyed wood fibres on aged timbers need to be removed by sanding and / or suitable chemical wood cleaner. CLEAN Clean to remove all

dirt, dust and all other surface contaminants by using a suitable cleaning agent and rinse off with clean water. Treat mould with a suitable

mould treatment.

REPAIR SURFACE IMPERFECTIONS Fill nail holes, cracks and other defects with a suitable wood filler and allow to dry thoroughly.

SANDING Sand dressed timber with fine sandpaper in direction of the grain and along the full length of the board. Round off all sharp edges

to a minimum of 2 mm radius in order to achieve an even film build and uniform paint coverage.
