Testing of Coating Materials: Owner reserves the right to invoke the following procedure: 1. Owner will engage the services of a qualified testing agency to sample coating materials. Contractor will be notified in advance and may be present when samples are taken. If coating materials have already been delivered to Project site, samples may be taken at Project site. Samples will be identified, sealed, and certified by testing agency. 2. Testing agency will perform tests for compliance with product requirements. 3. Owner may direct Contractor to stop applying coatings if test results show materials being used do not comply with product requirements. Contractor shall remove noncomplying coating materials from Project site, pay for testing, and recoat surfaces coated with rejected materials. Contractor will be required to remove rejected materials from previously coated surfaces if, on recoating with complying materials, the two coatings are incompatible. PART 3 - EXECUTION 3.1 EXAMINATION A. Examine substrates and conditions, with Applicator present, for compliance with requirements for maximum moisture content and other conditions affecting performance of the Work. B. Verify suitability of substrates, including surface conditions and compatibility, with existing finishes and primers. C. Proceed with coating application only after unsatisfactory conditions have been corrected. THE KENT 09 96 00 - THE KENT Issue Date 05.09.18 HIGH PERFORMANCE COATINGS THE KENT 1. Application of coating indicates acceptance of surfaces and conditions. 3.2 PREPARATION A. Comply with manufacturer's written instructions and recommendations in "MPI Architectural Painting Specification Manual" applicable to substrates and coating systems indicated. B. Remove hardware, covers, plates, and similar items already in place that are removable and are not to be painted. If removal is impractical or impossible because of size or weight of item, provide surface-applied protection before surface preparation and painting. 1. After completing painting operations, use workers skilled in the trades involved to reinstall items that were removed. Remove surface-applied protection if any. C. Clean substrates of substances that could impair bond of coatings, including dust, dirt, oil, grease, and incompatible paints and encapsulants. 1. Remove incompatible primers and reprime substrate with compatible primers or apply tie coat as required to produce coating systems indicated. D. Steel Substrates: Remove rust, loose mill scale, and shop primer if any. Clean using methods recommended in writing by paint manufacturer but not less than the following: 1. SSPC-SP 7/NACE No. 4. 2. SSPC-SP 11. 3. SSPC-SP 6/NACE No. 3. 4. SSPC-SP 10/NACE No. 2. 5. SSPC-SP 5/NACE No. 1. E. Shop-Primed Steel Substrates: Clean field welds, bolted connections, and areas where shop paint is abraded. Paint exposed areas with the same material as used for shop priming to comply with SSPC-PA 1 for touching up shop-primed surfaces. F. Galvanized-Metal Substrates: Remove grease and oil residue from galvanized sheet metal by mechanical methods to produce clean, lightly etched surfaces that promote adhesion of subsequently applied coatings. 3.3 APPLICATION A. Apply high-performance coatings according to manufacturer's written instructions and recommendations in "MPI Architectural Painting Specification Manual." 1. Use applicators and techniques suited for coating and substrate indicated. 2. Coat surfaces behind movable equipment and furniture same as similar exposed surfaces. Before final installation, coat surfaces behind permanently fixed equipment or furniture with prime coat only. 3. Coat backsides of access panels, removable or hinged covers, and similar hinged items to match exposed surfaces. 4. Do not apply coatings over labels of independent testing agencies or equipment name, identification, performance rating, or nomenclature plates. B. Tint each undercoat a lighter shade to facilitate identification of each coat if multiple coats of the same material are to be applied. Tint undercoats to match color of finish coat, but provide sufficient difference in shade of undercoats to distinguish each separate coat. THE KENT 09 96 00 - THE KENT Issue Date 05.09.18 HIGH PERFORMANCE COATINGS THE KENT C. If undercoats or other conditions show through final coat, apply additional coats until cured film has a uniform coating finish, color, and appearance. D. Apply coatings to produce surface films without cloudiness, spotting, holidays, laps, brush marks, runs, sags, ropiness, or other surface imperfections. Produce sharp glass lines and color breaks. 3.4 FIELD QUALITY CONTROL A. Dry Film Thickness Testing: Owner may engage the services of a qualified testing and inspecting agency to inspect and test coatings for dry film thickness. 1. Contractor shall touch up and restore coated surfaces damaged by testing. 2. If test results show that dry film thickness of applied coating does not comply with coating manufacturer's written recommendations, Contractor shall pay for testing and apply additional coats as needed to provide dry film thickness that complies with coating manufacturer's written recommendations. 3.5 CLEANING AND PROTECTION A. At end of each workday, remove rubbish, empty cans, rags, and other discarded materials from Project site. B. After completing coating application, clean spattered surfaces. Remove spattered coatings by washing, scraping, or other methods. Do not scratch or damage adjacent finished surfaces. C. Protect work of other trades against damage from coating operation. Correct damage to work of other trades by cleaning, repairing, replacing, and recoating, as approved by Architect, and leave in an undamaged condition. D. At completion of construction activities of other trades, touch up and restore damaged or defaced coated surfaces. END OF SECTION 09 96 00
