SP0188-2006 NACE Discontinuity (Holiday) testing of new protective coatings on conductive substrates.

IV. Surface Preparation

A. Prior to commencement of work, all parts shall be visually inspected.

B. Rough welds and other sharp projections shall be ground smooth by the end user or as designated by the inspector.

C. Prior to abrasive blast or power-tool cleaning the substrate, all contaminants such as dirt, dust, oil and/or grease must be removed in accordance with SSPC-SP1.

D. The substrate shall not contain soluble salt concentrations in excess of the following values: chloride levels—3 ppm (micrograms per square centimeter), nitrates—5 ppm, sulfates—10 ppm. Surfaces with soluble salt concentrations in excess of these levels shall be treated until satisfactory results are achieved.

E. Prior to abrasive blasting or grinding, the metal surface shall be dry and warmed to a temperature at least 3°C (5°F) above the dew point to prevent oxidation of the part af-ter cleaning. The applicator shall use a contact thermometer, psychrometer, and psy-chrometric charts, or equipment that provides equivalent accuracy, to monitor these environmental requirements.

F. All parts that are not to be abraded shall be adequately protected.

G. All large surfaces to be coated will be prepared by abrasive blast cleaning. Smaller sur-faces (less than 50 ft2) may be prepared by power tool cleaning using a hand-held an-gle grinder. All blast media will be clean and clear of any contaminates, have a maxi-mum of one percent (1%) free silica, and will meet the specification of the coating manufacture. A 24-grit 3M grinding disk (recommended for coating), a metal grinding disk (required for steel) or equivalent should be used with the angle grinder.

H. All compressors shall be in good working order and have adequate separators, filters, and drains to ensure contaminants such oil and water are not deposited onto the steel surface. Accumulation of oil and moisture shall be removed by regular purging.

I. For bare steel application an anchor pattern profile will be produced with a minimum average of 0.075 mm (3.0 mils). Individual measurements shall not be less than 0.065 mm (2.5 mils). Profile measurements shall be taken with replica tape and spring mi-crometer in accordance with NACE RP0287-2002.

J. For larger parts and/or structures (> 50 ft2), the substrate shall be abrasive blasted in accordance with the NACE No. 2/SSPC-SP10 specification to achieve an anchor pat-tern that is both sharp and angular. Smaller surface areas (< 50 ft2) may be power tool abraded using an angle grinder with either a metal grinding disk (for steel) or 24-grit


EFFECTIVE: 01/09/12

3M grinding disk (for coating and/or steel) or equivalent in accordance with SSPC-SP11 specification. Grinding should be done in such a way to achieve the roughest sur-face possible, and the direction of the final grind marks should run perpendicular to the flow of water in the pipe. The applicator shall ensure the proper surface finish is attained by regular checks with the SSPC-VIS-1-89 Standard. Profile depth shall be check using replica tape and a spring micrometer (NACE RP0287-2002). Note: pro-file, particularly with power-tool preparation, should be deep enough such that it is very noticeable when scraping the end of a fingernail across the profile grooves.

K. When over-coating existing coating material the applicator will verify adhesion com-patibility with the coating manufacturer before proceeding. Once compatibility is de-termined, the existing coating shall be sweep blasted or abraded with a grinder to re-move the gloss and provide a roughened surface suitable for over-coating. This process should remove approximately 1-3 mils of coating.

L. Existing coating shall be feathered 4 cm (1.5 in.) to 8 cm (3 in.) when coating adjacent bare steel, such as girth welds. Prior to coating, the applicator will tape off, using duct tape, a line between feathered coating and the remaining non-blasted coating prior to application of new coating material, making sure that edge of tape is on the roughened coating.

M. Profile measurements will be taken, at a minimum, at the start of each shift, after a shut down to refill blasting pot, and after every hour of continuous blasting.

N. Cleaned surfaces shall be dry air blasted and either brushed off or vacuumed, in a mat-ter to remove dust and debris prior to coating, and shall be coated before any rust blooming occurs. Any cleaned steel showing rust stains shall be re-prepared prior to coating.

V. Coating Application

A. The coating shall be applied according to the proceeding guidelines.

B. Thinning is not allowed.

C. The coating thickness shall be specified by the end user or the inspector. The mini-mum thickness for DuraShield 210 & DuraShield 210-61 is 20 mils. The applicator shall measure and record coating thickness using a thickness gauge that is acceptable to the end user/inspector.

D. The relative humidity, dew point and steel surface temperature shall conform to the recommended parameters outlined in the DuraShield 210 and DuraShield 210-61 Technical Data Sheets. Ensure that the resin (Part A) and activator (Part B) compo-nents are within the recommended product Application Temperatures for the chosen application method as listed on the respective Technical Data Sheet. The applicator shall use a contact thermometer, a psychrometer and psychrometric charts, or equip-ment that provides equivalent accuracy, to monitor these environmental requirements.

E. A list of approved application equipment can be found in Appendix 1.

F. Application shall be done in a professional manner, mitigating runs and sags and pro-viding complete coverage on all surfaces, including difficult to spray areas like welds, seams and angles. Application shall be accomplished in a manner that achieves as smooth and uniform of a coat as possible.

G. If recoating is required, it must be accomplished prior to the maximum recoat window as listed on the Technical Data Sheet for the respective product. If the maximum re-coat window is exceeded, then follow the instructions in Section IV.J above.


EFFECTIVE: 01/09/12

TM

H. Refer to the DuraShield 210 and DuraShield 210-61 Technical Data Sheets for cure time required before placing system into service.

VI. Inspection and Testing

A. Visual

1. Coating shall be uniform in color. The coating shall be visually inspected and found to be free of blisters, cracks, pinholes, missed areas and excessive rough-ness.

2. Sags and runs shall be kept to a minimum. Excessive runs can be sanded smooth and overcoated with a layer of DuraShield 210 or DuraShield 310.

B. Coating Thickness

1. During continuous spray operations, the coating thickness shall be measured us-ing a wet film thickness gage whenever feasible. The dry film coating thickness shall be tested using a properly calibrated magnetic pull off or eddy current equipment after completion of each pipe. In either measure, if the thickness of the coating is below the minimum specified millage anywhere along the length of the pipe, then adjustments must be made to the spray system to account for this.

2. In field spray and hand application projects, the coating thickness shall be meas-ured using a wet film thickness gage whenever feasible. At a minimum, the thickness shall be measured for every 50 ft2 of sprayed area or every joint for joint repair applications. The dry film coating thickness shall be tested using a properly calibrated magnetic pull off or eddy current equipment after completion of each pipe or joint for joint repair applications. In either measure, if the thick-ness of the coating is below the minimum specified millage anywhere along the length of the pipe, then adjustments must be made to the spray system to ac-count for this.

C. Holiday Testing

1. Holiday testing will be conducted on the completed coating after cure or 24 hours, whichever is less, using a high voltage spark test in accordance with NACE Standard RP-0188.

2. Coating shall be at 75% or greater of its fully cured hardness value prior to holi-day testing.

3. Coating thickness used for holiday detection shall be the minimum specified coating thickness.

4. All holidays shall be plainly marked immediately after detection and shall be re-paired according to Section VII in this specification.

5. Holiday testing will be performed in such a way as to mitigate possible damage to the coating by performing as few of passes as required over the coating.

VII. Coating & Joint Repairs

A. Coating and joint repairs may be made with DuraShield 210, DuraShield 310, Dura-Shield 310 Trowel Grade, or the DuraShield 310 JARS (Joint & Repair System) kit. All three systems are available in NSF certified versions.

B. Please follow the Application Specifications for the particular product chosen for the repairs.

H. Once Base Coat resin container ―A‖ is thoroughly mixed, the applicator will pour all of the Activator 9000 from one of the containers marked ―Activator 9000 – Part B‖ into container ―A‖ in such a manner to prevent spilling any of activator ―B‖.

I. Once Activator Part ―B‖ is completely poured into Base Coat resin ―A,‖ the applicator will immediately mix both components – resin ―A‖ and activator ―B‖ – together using a cordless or electric drill outfitted with a paint/epoxy mixing blade. The mixing of com-ponents ―A‖ and ―B‖ shall be done in such a manner to insure uniform mix has been achieved. This process requires that the applicator use supplied mixing stick to scrape the sides and bottom of the container during the mixing process. The mixing process shall take no less than 2 minutes. When mixing is complete, the mixture will be of uni-form color and consistency.

J. After mixing, the applicator will immediately apply the Base Coat material first to the weld joint (if applicable). The applicator will use the supplied brush to apply the mixed coating to the prepared surface and do so in such a manner to keep sags and runs to a minimum, provide adequate cover in angles and crevices, and to provide a smooth and uniform surface. Special care should be taken of the weld corners and seams. Note: DuraShield 310 polyurethane is not like a paint; it is much thicker. As such, rather than merely dipping the brush into the mixed coating, it is recommended that the brush be actually used like a trowel or putty knife, delivering copious amounts of the coating to the substrate with each dip. It can then be brushed out once delivered to the substrate.

K. Once the weld is completely coated, the remaining ―mixed‖ material should be brush-applied to the steel surrounding the welds (commonly called the holdbacks), com-pletely covering all exposed steel. The applicator shall not scrape the sides or bottom of the ―mixed‖ container during the application in an attempt to use all material, as it is not possible to adequately mix the material on the sides and bottom of the container. If more material is needed to finish initial coating process, the applicator will mix more material according to steps G. to I.

L. The application process of the Base Coat shall be done in such a manner to apply all of the mixed coating within the allowable pot life of 12 minutes. The Base Coat is de-signed for and should be applied at a thickness of 20-25 mils in one coat.

M. Allow the Base Coat to cure for approximately 2 - 2.5 hours at 24°C (75°F). Warmer temperatures will speed the cure of the coating and colder temperatures will slow its curing process. The Base Coat should be ―beyond stringback‖ (see definition in Section 2.8), but can still be sticky, prior to applying the Top Coat.

N. Once the Base Coat is sufficiently cured, the ―Top Coat‖ can be applied. Be sure to ap-ply the Top Coat to the Base Coat within the ―Maximum Recoat Time‖ as is listed in the DuraShield 310-61 JARS Technical Data Sheet.

O. Follow steps G. through I. for mixing the Top Coat.

P. After thoroughly mixing the Top Coat components, the applicator will immediately ap-ply the Top Coat. The applicator will use the supplied brush to apply the mixed coating to all areas within the tape lines – including onto both the Base Coat and the prepared existing coating (over-coat) areas. This should be done in such a manner to keep sags and runs to a minimum, provide adequate cover in angles and crevices, and to provide

a smooth and uniform surface. The applicator shall not scrape the mixed container during the application process to use all material. If more material is needed to finish initial coating process the applicator will mix more material using the previously out-lined steps.

Q. Refer to the and DuraShield 310-61 JARS Technical Data Sheet for cure time required before placing system into service.

2. Sags and runs shall be kept to a minimum. Excessive runs can be sanded smooth and overcoated with a layer of DuraShield 310 or DuraShield 310-61.


1. The coating thickness shall be measured using a wet film thickness gage. At a minimum, the thickness shall be measured for every 50 ft2 of applied area or every joint for joint repair applications. The dry film coating thickness shall be tested using a properly calibrated magnetic pull off or eddy current equipment after completion of each joint or repair. In either measure, if the thickness of the coating is below the minimum specified millage anywhere along the length of the pipe, then adjustments must be made to the spray system to account for this.

I. Substrate Profile Requirements

1. Bare steel application – an anchor pattern profile will be produced with a mini-mum average of 0.075 mm (3.0 mils). Individual measurements shall not be less than 0.065 mm (2.5 mils). Profile measurements shall be taken with replica tape and spring micrometer in accordance with NACE RP0287-2002.

2. Concrete application – surface profile should meet ASTM D4259, ICRI CSP 4-6 or be comparable to coarse sandpaper.

I. Preparation Methods

1. Steel Substrates – The applicator shall ensure the proper surface finish is at-tained by regular checks with the SSPC-VIS-1-89 Standard. Profile depth shall be check using replica tape and/or structures a spring micrometer (NACE RP0287-2002).

a. Larger parts and/or structures (> 50 ft2) – the substrate shall be abrasive blasted in accordance with the NACE No. 2/SSPC-SP10 specification for steel.

b. Smaller surface areas (< 50 ft2) – may be power tool abraded using an angle grinder with either a metal grinding disk (for steel) or 24-grit 3M grinding disk (for coating and/or steel) or equivalent in accordance with SSPC-SP11 specification. Grinding should be done in such a way to achieve the rough-est surface possible. Note: profile, particularly with power-tool prepara-tion, should be deep enough such that it is very noticeable when scraping the end of a fingernail across the profile grooves.

2. Concrete substrates The applicator shall ensure the proper surface finish is at-tained by regular checks with the SSPC -SP13 Standard.

a. Larger substrates (> 50 ft2) – shot blast or abrasive blast to remove lai-tance, curing compounds, sealers and other contaminants and to provide surface profile ASTM D4259, ICRI CSP 4-6.

b. Smaller surface areas (< 50 ft2) – may be power tool abraded using an an-gle grinder with a 24-grit 3M grinding disk, hand-held scarifier or equiva-lent.

J. When over-coating existing coating material the applicator will verify adhesion com-patibility with the coating manufacturer before proceeding. Once compatibility is de-termined, the existing coating shall be sweep blasted or abraded with a grinder to re-move the gloss and provide a roughened surface suitable for over-coating. This process should remove approximately 1-3 mils of coating.

K. Existing coating shall be feathered 4 cm (1.5 in.) to 8 cm (3 in.) when coating adjacent substrate. Prior to coating, the applicator will tape off, using duct tape, a line between feathered coating and the remaining non-blasted coating prior to application of new coating material, making sure that edge of tape is on the roughened coating.

L. Profile measurements will be taken, at a minimum, at the start of each shift, after a shut down to refill blasting pot, and after every hour of continuous blasting.

M. Cleaned surfaces shall be dry air blasted and either brushed off or vacuumed, in a mat-ter to remove dust and debris prior to coating, and shall be coated before any contami-nation occurs. Any cleaned steel showing contamination shall be re-prepared prior to coating.

C. The coating thickness shall be specified by the end user, inspector, or manufacturer. The minimum thickness for DuraShield 310 & DuraShield 310-61 is 20 mils. The ap-plicator shall measure and record coating thickness using a thickness gauge that is ac-ceptable to the end user/inspector.

D. The relative humidity, dew point and steel surface temperature shall conform to the recommended parameters outlined in the DuraShield 310 and DuraShield 310-61 Technical Data Sheets. Ensure that the resin (Part A) and activator (Part B) compo-nents are within the recommended product Application Temperatures for the chosen application method as listed on the respective Technical Data Sheet. The applicator shall use a contact thermometer, a psychrometer and psychrometric charts, or equip-ment that provides equivalent accuracy, to monitor these environmental requirements.

E. A list of approved application equipment can be found in Appendix 1.

F. For application of DuraShield 310 to concrete, masonry and non-ferrous metal sub-strates, an application of LifeLast Primall-160 100% epoxy primer must be performed prior to applying the DuraShield 310. Application of Primall-160 shall be accom-plished as per the Primall-160 Application Instructions Sheet.

G. Substrate shall be clean, dry and free of any contaminants that may adversely affect the adhesion of the coating system. When coating primed substrates, substrate must be completely coated with Primall-160, and the Primall-160 must be cured to the level required in the Primall-160 Epoxy Primer Technical Data Sheet.

H. Application shall be done in a professional manner, mitigating runs and sags and pro-viding complete coverage on all surfaces, including difficult to spray areas like welds, seams, angles, and bugholes. Application shall be accomplished in a manner that achieves as smooth and uniform of a coat as possible.

I. Should the substrate need to be presurfaced prior to applying the DuraShield 310 coat-ing – to smooth overly-rough substrates, address excessive bugholing, etc. – then the recommended presurfacing methods are as follows:

1. Trowel a non-shrink, quick-setting, cementatious grout into the holes. The grout must achieve compressive strengths of 2000 psi at 2 hours and 4000 psi at 24 hours per ASTM C 109. The patched areas must be abrasive blasted and cleaned prior to the priming process.

2. Trowel DuraShield 310 or DuraShield 310 trowel-grade into the holes per the Du-raShield 310 Hand Application Instructions sheet. This must be done after the surface has been primed.

3. Fill the holes with DuraShield 310 during spray application. Use care not to spray too many mils at one time and cause a sag or run. DuraShield 310 can be applied at up to 80 mils in one coat. This option must be done after the surface has been primed.

J. If recoating is required, it must be accomplished prior to the maximum recoat window as listed on the Technical Data Sheet for the respective product. If the maximum re-coat window is exceeded, then follow the instructions in Section IV.J above.

DURASHIELD™ 210-61

TECHNICAL DATA SHEET EFFECTIVE: 10/08/12

CHEMICAL DESCRIPTION Solventless Aromatic Polyurethane, Chemical Cure, ASTM D16 Type V

USAGE DuraShield 210-61 (DS210-61) is a 100% solids, two-component polyurethane coating that contains no volatile organic compounds (VOC), solvents or extending fillers. Formulated specifically as a potable water tank, pipe, valve and fitting lining product, DS210 is a hard, durable, chemi-cal resistant coating that also provides great flexibility and impact resistance for ferrous and non-ferrous metals, con-crete and other surfaces. By employing hydrophobic poly-urethane resins, DS210-61 has a very low water absorption rate – lower even than most epoxies – and excellent ca-thodic disbondment resistance. The hydrophobic proper-ties of DS210-61 also impart improved tolerance to mois-ture, both in the container and during application. This allows DS210-61 to cure to a hard, flexible, durable film with a very glossy, extremely well-adhered, impermeable finish. DS210- 61 is designed specifically to provide very fast cure times, while at the same time demonstrating ex-cellent adhesion. DS210-61 is applied by an approved Life-Last spray system.

CHEMICAL DESCRIPTION Solventless Elastomeric Aromatic Polyurethane, Chemical Cure, ASTM D16 Type V

USAGE DuraShield 310-61 (DS310-61) is a 100% solids, two-component polyurethane coating that contains no volatile or-ganic compounds (VOC) or solvents. Formulated as a hard, durable, chemical resistant coating, DS310-61 also provides good flexibility and impact resistance for ferrous and non-ferrous metals, concrete and other surfaces. DS310-61 pro-vides the low permeability and chemical resistance of an epoxy, with the durability, flexibility and fast cure times of polyure-thanes. This blend of properties allows for excellent applica-tion characteristics, while at the same time making it ideal for long-term immersion protection. While DS310-61 has fast cure times, the nature of its chemistry allows for long recoat win-dows relative to comparative 100% solid urethanes. This helps to mitigate layering and recoat adhesion problems. DS310-61 is also formulated to provide optimal build properties. DS310-61 is formulated to provide optimal build properties, allowing for the required coating thickness to be applied in one coat – even on seams, welds and rivets – while at the same time pro-viding good overcoat properties and aesthetics. Application of DuraShield 310-61 is primarily accomplished by spray (using an approved LifeLast spray system), however hand-applicable versions are also available.

DURASHIELD™ 310-61 JARS


CHEMICAL DESCRIPTION Solventless Elastomeric Aromatic Polyurethane, Chemical Cure, ASTM D16 Type V

USAGE DuraShield 310-61 (DS310-61) is a 100% solids, two-component polyurethane coating that contains no volatile or-ganic compounds (VOC), solvents or hydrocarbon extending fillers. The DS310-61 Joint & Repair System (JARS) is a user friendly polyurethane formulation that can be hand or spray applied to joints and for repairs. The long pot life of DS310-61 allows for hand application on larger surfaces, and the short cure time decreases the waiting time between coats. The hy-drophobic nature of DS310-61 makes it suitable for hand appli-cation without foam formation, even in humid environments. DS310-61 provides the low permeability and chemical resis-tance of an epoxy, with the durability, flexibility and fast cure times of polyurethanes. This blend of properties results in excellent application characteristics, while at the same time making it ideal for long-term immersion protection. While DS310-61 has fast cure times, the nature of its chemistry allows for long recoat windows relative to comparative 100% solid urethanes. This helps to mitigate layering and recoat adhesion problems. DS310-61 is also formulated to provide optimal build properties. Complete encapsulation of welds and joints can be accomplished by two 20-25 mil coats by hand.
