9.4: Mixing and Application of Sealing and Coating System

9.4.1: Preparation of Coating Materials for Application: Each of the primer, intermediate, and topcoat materials is a two-component material supplied in separate containers.

9.4.2: Mixing Sealant, primer, and Intermediate Coat Materials: Mix in accordance with manufacturer's instructions, which may differ for each product. Do not mix partial kits, or alter mix ratios. Mix materials in same temperature and humidity conditions specified in paragraph DELIVERY AND STORAGE. Allow mixed material to stand for the required induction time based on its temperature.

9.4.3: Mixing Top Coat Materials: Do not mix partial kits, or alter mix ratios. Mix polyurethane coating materials in same temperature conditions specified in paragraph DELIVERY AND STORAGE. The polyurethane coating material is moisture sensitive and any introduction of moisture or water into the material during mixing or application will shorten usable pot life. Use a mixer that does not create a vortex. Do not add solvent without specific written recommendation from the manufacturer. No induction time is required, only thorough agitation of the mixed material.

9.4.4: Pot Life: As specified by manufacturer, but no more than: Epoxy primer and intermediate materials 4 hours and Polyurethane topcoat materials 2 hours.

9.4.5: Application Conditions and Recoat Windows:

9.4.5.1: The application condition requirements for the coating system are very time and temperature sensitive, and are intended to avoid the delamination problems frequently found on industrial structures. Plan coating application to ensure that specified temperature, humidity, and condensation conditions are met. If conditions do not allow for orderly application of primer, stripe coat, intermediate coat and topcoat, application process must stop.

9.4.5.2: Air and steel surface temperature must be between 60 and 100 degrees F during application and the first four hours of cure for epoxy coats and the first eight hours of cure for polyurethane coats. Steel surface temperature must be more than 5 degrees F above the dew-point of the ambient air for the same period.

9.4.5.3: Use data specified by manufacture to determine appropriate recoat windows for each coat after the initial coat. Apply each coat during appropriate RECOAT WINDOW of preceding coat. If a RECOAT WINDOW is missed, the minimum and maximum primer and intermediate coat thickness may be adjusted to accommodate a FILL COAT, however, requirements for total epoxy coating thickness and total coating thickness will not be modified. Missing more than one RECOAT WINDOW may require complete removal of coating if maximum total coating thickness requirements cannot be achieved.

9.4.5.4: If coating is not applied during RECOAT WINDOW, gloss removal may be required as determined by COR. If next planned coat is topcoat, apply FILL COAT if required to fill sanding marks. Sanding marks from GLOSS REMOVAL of intermediate coat reflecting through topcoat will be considered as noncompliant.

9.4.5.5: FILL COAT - Where indicated, apply coat of intermediate coat epoxy, at 2 to 3 mils DFT, then apply next specified full coat within recoat window of FILL COAT. A FILL COAT may be used to adjust coating thickness to comply with requirements or to fill sanding marks in intermediate coat.

9.4.5.6: GLOSS REMOVAL - Where required, hand sand in a linear fashion to remove gloss using 120-200 grit wet/dry sandpaper, followed by solvent wiping with a clean rag soaked with denatured alcohol to remove all dust. GLOSS REMOVAL of primer coat is to scarify surface and shall consist of removal of approximately 1 mil of coating. If steel is exposed during GLOSS REMOVAL, repair in accordance with paragraph

PROCEDURE FOR HOLIDAY AND SPOT REPAIRS OF NEWLY APPLIED

COATING. GLOSS REMOVAL of intermediate coat may include removal of up to 3 mils of coating to avoid excess thickness, prior to application of FILL COAT.

9.4.6: Application of Coating System and Joint Sealant: Apply coatings in accordance with SSPC PA 1 and as specified herein. Apply coatings to surfaces that meet all stated surface preparation requirements.

9.4.7: Paint Application Methods: Paint may be applied by the following methods unless otherwise stated: Brushing or Roller application

9.4.7.1: The method best suited for application depends on the type of paint, degree of complexity of the surface being painted, paint viscosity, and other considerations. The paint manufacturer and a professional painting contractor must use best application method to meet the intent of the specifications for the tanks being painted.

9.4.7.2: After application of primer coat and prior to application of each subsequent coat, perform testing prescribed in paragraph PRE-APPLICATION TESTING FOR SURFACE CONTAMINATION, as necessary, to ensure minimal inter-coat contamination. Generally, oil and grease contamination and soluble salts contamination are not encountered if subsequent coats are applied within specified recoat windows and unusual atmospheric events do not occur.

9.4.7.3: Apply each coat in a consistent wet film, at 90 degrees to previous coat.

9.4.7.5: Ensure that primer and intermediate coat "cold joints" are no less than six inches from welds. Apply stripe coat by brush. Apply all other coats by roller application unless approved by COR. Use appropriate controls to prevent airborne coating fog from drifting beyond 15 feet from the structure perimeter. Cover or protect all surfaces that will not be coated. The cleanliness, temperature, recoat windows, and airborne paint containment requirements may necessitate the use of enclosures, portable shelters, or other appropriate controls.

9.4.8: Application of Primer: When applying primer coat, maintain constant agitation of paint to ensure that zinc does not settle in container.

9.4.9: Application of Stripe Coat: Apply a stripe coat of intermediate coat epoxy material within RECOAT WINDOW of primer, allowing sufficient dry time to allow application of intermediate coat within RECOAT WINDOW of primer. Apply by brush, working material into corners, crevices, angles, and welds, and onto outside corners and angles.

9.4.10: Application of Intermediate Coat: Apply intermediate coat within RECOAT WINDOW of primer coat.

9.4.11: Non-skid for Ladder and Top: Install non-skid adhesive to ladder and grit on top to manway opening. Where non-skid grit is required, apply a second intermediate coat, and immediately follow with application of non-skid grit, broadcast at the rate of 2 pounds per 100 square feet, and backroll. Apply topcoat as specified.

9.4.12: Application of Topcoat: Make all required repairs to primer and intermediate coats as specified in paragraph entitled "Procedure for Holiday and Spot Repairs of Newly Applied Coating" prior to applying topcoat. Apply topcoat within RECOAT WINDOW of intermediate coat. The polyurethane topcoat may require multiple passes to achieve desired aesthetics and required thickness. Consult manufacturer for thinning and application procedures for anticipated temperature, humidity, and wind conditions. Touch-up blemishes and defects within recoat window of polyurethane topcoat. Retain sample of polyurethane topcoat, from the same batch used to coat structure, to make touch-ups that might be required later.

9.4.13: Application of Joint Sealant: Apply joint sealant to back-to-back steel joints that are less than 3/8 inches wide and are not seal welded. Apply sealant to top and bottom, or each side, of narrow joints. Apply sealant within 48 hours of application of the topcoat, and touch-up with topcoat after appropriate cure of the sealant.

9.4.14: Procedure for Holiday and Spot Repairs of Newly Applied Coating: Repair coating film defects at the earliest practicable time, preferably before application of the succeeding coat.

Observe all requirements for soluble salts contamination, cleanliness between coats, and application conditions. Prepare defective area in accordance with surface preparation requirements of this specification and feather coating as required to leave 4 inches of each succeeding coat feathered and abraded. Protect adjacent areas from damage and overspray. Remove dust and solvent wipe the prepared area plus an additional 4 inches beyond the prepared area with clean denatured alcohol. Apply each coat within RECOAT WINDOW of preceding coat. Within four hours of preparation, apply zinc-rich primer to prepared steel and feather onto prepared primer.

Apply intermediate coat to primed area and feather to prepared intermediate area. Apply topcoat to intermediate coat and feather to prepared topcoat. Apply each repair coat to approximate thickness of surrounding coating system.

9.4.15: Structure Occupancy after Coating Application: Use clean canvas or other approved shoe covers when walking on coated surfaces, regardless of curing time allowed. For heavily trafficked areas, provide cushioned mats for additional protection.
