Correct conditions detrimental to the proper and timely completion of the work. Do not proceed with installation until unsatisfactory conditions have been corrected.


3 03 Installation

3 03 01 General Verify that materials to be used for the work comply with requirements in specifications and schedules.

3 03 02 Sprayed Mineral Coatings

3 03 02 01 Surface Preparation

3 03 02 01 01 General Any substrates which are not supposed to receive mechanical retention shall be

carefully cleaned to make sure they are free from oil, grease, dirt, dust, scale, loose paint, mould release agents or other materials or conditions likely to impair adhesion.

3 03 02 01 02 Painted Surfaces 01.0 Old, loose and flaking paint shall be removed prior to spraying,

unless mechanical retention is used. Apply spray over existing paint only if fire resistance data of the intended coating are showing that there will be no adverse effect on the performance.

02.0 An alkali-resistant sealer coat shall be applied if the existing paint is not chemically compatible with the spray.

03.0 Only newly applied compatible primers are regarded to be a proper base for direct spray application.

3 03 02 01 03 Metals Primers are usually not needed for Portland Cement-bound sprays if the building

environment remains dry after construction. Under continual damp conditions it may be advisable to prime also galvanized steel to prevent ‘white rusting’.

or gypsum board. Gypsum-based sprays shall only be applied to plaster-based products if recommended by the manufacturer.

3 03 02 01 05 Movement Joints Where movement joints are incorporated into the structure it is essential to ensure the

spray does not bridge the joint. Use proprietary stop beads or similar items on either side, and spray against them. Protect the joint from spray.

3 03 02 01 06 Mechanical Retention 01.0 Mechanical retention shall be provided unless:

a) Where there is evidence from fire resistance tests to show that there is adequate bond between the spray and the substrate. b) The spray is locked in position by virtue of the shape of the elements to be coated (see samples in Annex 6, figure 2)

02.0 Where the dimensions of the cross section are very large (i.e. web greater than 650 mm and flange greater than 325 mm, mechanical retention shall be applied even for shapes illustrated in figure 2.

03.0 Mechanical retention shall be applied in all cases similar to illustrations shown in Annex 6, figure 3

04.0 The material, type and fixing (see also Annex 6, Table 1and Figure 1) of the mechanical retention shall be approved by the Engineer prior to execution.

3 03 02 02 Spray Application Particular care shall be taken to ensure that the required thickness is built up in the

recommended manner so that good cohesive strength is obtained. Any spillage or overspray shall be cleaned off at the end of each working period.

When using adhesives, the manufacturer’s recommendations shall be followed.

The finished density of spray shall be within ±15 % of the density stated by the manufacturer.

The spray on the flange shall not be permitted to taper to the flange edges.

Apply topcoat where indicated.

Gauges left in position within the spray and are of plastics, shall not have a cross section of more than 20 mm2 and not be longer than the depth of the spray.

Frequency of measurement: Provide one thickness measurement for each unit of 1,5 m x 1,5 m, i.e. four measurements for an area of 3 m x 3 m. For areas greater than 3 m x 3 m an additional thickness measurement shall be made for each unit of 3 m x 3 m. All measurements shall be recorded and submitted to the Engineer.

Contoured substrate: Steel ‘I’ section columns and beams shall at least be measured every 3 m on each surface.

When substrates are overlaid with metal lath, for example keying mesh, the spray thickness should be taken to be the thickness measured to the face of the lath.




3 03 03 Magnesium Oxychloride Coating

3 03 03 01 Surface Preparation 01.0 Old, loose and flaking paint shall be removed prior to spraying,

3 03 02 03 Sealant Application 01.0 Install sealant by proven techniques that result in sealants directly

contacting and fully wetting joint substrates, completely filling recesses and providing uniform, cross-sectional shapes and depths relative to joint widths which allow optimum sealant movement capability.

02.0 Tooling: Nonsag sealants shall be tooled immediately after application prior to skinning and curing. Tool sealant to form smooth, uniform beads of configuration indicated, to eliminate airpockets and to ensure contact and adhesion. Remove excess sealant from surfaces adjacent to joint. Do not use tooling agents, which discolor sealant or adjacent surfaces or are not approved by sealant manufacturer.

03.0 Concrete pavement sealing: Make sure, that at no time during the anticipated operating cycle of the joint, the sealant will protrude above the surface of the concrete pavement. To ensure this, it will be necessary to recess the level of the sealant 5 to 8 mm below the pavement surface, depending on the temperature prevailing at time of application (see Annex 6, Figure 2).

04.0 Firestopping sealant: Follow strictly manufacturer's, respectively testing agencies instructions for the installation of sealant and required backing materials to ensure the indicated fire ratings after curing.

3 03 02 04 Installation of Preformed Foam Seals - Compression Seals Install each length of sealant immediately after removing protective wrapping, taking care not to pull or stretch material, and to comply with sealant manufacturer's directions for installation methods, materials and tools which produce seal continuity at ends, turns and intersections of joints.

3 04 Field Quality Control 3 05 Adjusting and Cleaning Clean off excess sealants or sealant smears adjacent to joints as work progresses by methods and with cleaning materials approved by manufacturer of joint sealers and joint substrates.

3 06 Demonstration 3 07 Protection Protect joint sealers during and after curing period from contact with contaminating substances or from damage resulting from construction operations, to be without deterioration or damage at time of handing over. If, despite such protection, damage occurs, cut out and remove this parts immediately and reseal joints with new material to produce joint sealer installations with repaired areas indistinguishable from original work and approved by the Engineer.
