Specifications include, but are not limited to: Materials shall comply with the requirements of the Safe Drinking Water Act and other federal requirements. Proprietary formulations will be acceptable provided the coating is of the same generic type and that the performance of the formulation offered meets or exceeds the performance of the formulation defined in the below referenced coating standard. a. Coatings used on wet interior surfaces of the tank shall have been tested and certified for potable water contact in accordance with NSF/ANSI 61. They shall have been evaluated for long-term fresh water resistance at temperatures up to 200˚F, and the system shall have demonstrated satisfactory service in fresh water at temperatures up to 200˚F for at least eighteen (18) months. Any coating that cannot meet these requirements shall not be used. b. Coating Standard – Inside coating system No. 2 (ICS-2) is a three-coat, two-component epoxy coating system and is the coating system to be used for the purpose of this job. 1) The coating system shall include a primer that shall contrast in color with the color of the intermediate coat. The materials shall consist of (1) paint 1, a three-coat system of noncoal tar-containing two-component epoxy material in accordance with ANSI/AWWA C210, consisting of a prime coat and two finish coats, or alternatively, three coats of the same epoxy coating without the use of a separate primer; or (2) Paint 2, proprietary formulations in accordance with paragraph 2.4.1. 2.5 Coating Materials: 2.5.1 General – Coatings used on the interior surface of the tank shall be merchantable and suitable for the intended service and shall be delivered in unopened containers. Coating materials shall be as indicated in paragraph 2.4.1 b. 2.5.2 Labels – The containers in which coating materials are delivered shall be marked with the manufacturer’s name, product name or number, date of manufacture or expiration of shelf-life date, batch number, and safety precautions. 2.6 Surface Preparation: 2.6.1 The following surface preparation requirements shall be followed unless the coating manufacturer has more stringent requirements, in which case, the more stringent requirements shall prevail. 2.6.2 The existing coating system is not a candidate for overcoating so all existing coatings shall be removed and the surfaces blast cleaned in accordance with SSPC-SP10/NACE No. 2. The blast-cleaned surface shall have a surface profile that is appropriate for the specific primer and coating system, in accordance with the coating manufacturer’s recommendations. 2.6.3 The contractor shall prepare the interior floor, walls, ceiling and cover via vapor blasting to remove the existing failed lining, corrosion, and salt contaminates (if applicable) to achieve the desired cleanliness and profile for acceptance of the repair systems. The contractor shall collect all blast media and fugitive dust. If applicable, all cutting and welding shall be performed on the inside of the steel tank before any cleaning and coating are done. 2.6.4 The contractor shall be responsible to contain any fine dust and fugitive debris produced by paint removal, including use of a temporary shroud, drop cloths and filtered vacuum. All costs to reduce the amount of airborne debris shall be the borne of the contractor. The materials then will be gathered and immediately disposed of properly. Dust and debris will not be allowed to accumulate and shall be cleaned on a daily basis. All welds on the interior of the tank and all areas of abraded shop coat shall be blasted to “near white” metal in accordance with the provisions of SSPC-SP10. The blast should produce an anchor profile between 3.0-4.5 mils. All blast media and other debris will be removed from the tank and properly disposed. Blasted surfaces shall be coated as specified on the same day they are blasted. 2.6.5 The contractor shall thoroughly clean and degrease the interior surface with acetone. 2.6.6 The contractor shall rebuild any areas of pitted steel with a high-temperature resistant, paste grade system. Application shall take place after the interior surface preparation and prior to the coating to rebuild pitting damage and produce a flush surface as needed.
