PART 3 - EXECUTION <br /> 3 . 1 EXAMINATION <br /> A. Examine substrates and conditions, with Applicator present, for compliance with requirements for <br /> maximum moisture content and other conditions affecting performance of work. <br /> 1 . Maximum Moisture Content of Substrates : When measured with an electronic moisture meter as <br /> follows : <br /> a. Masonry (Clay, Cement Plaster Substrate and CMU) : 12 percent. <br /> 2 . Verify compatibility with and suitability of substrates, including compatibility with existing <br /> finishes or primers. <br /> 3 . Begin coating application only after unsatisfactory conditions have been corrected and surfaces are <br /> dry. <br /> 4 . Coating application indicates acceptance of surfaces and conditions. <br /> 3 .2 PREPARATION <br /> A. Comply with manufacturer's written instructions and recommendations in "MPI Architectural Painting <br /> Specification Manual" applicable to substrates indicated. <br /> B . Remove plates, machined surfaces, and similar items already in place that are not to be coated. If <br /> removal is impractical or impossible because of size or weight of item, provide surface-applied protection <br /> before surface preparation and coating . <br /> 1 . After completing coating operations, reinstall items that were removed; use workers skilled in the <br /> trades involved. <br /> C . Clean substrates of substances that could impair bond of coatings, including dirt, oil, grease, and <br /> incompatible paints and encapsulants . <br /> 1 . Remove incompatible primers and reprime substrate with compatible primers as required to <br /> produce coating systems indicated. <br /> D . Cement Plaster Substrates: Remove efflorescence and chalk. Do not coat surfaces if moisture content <br /> or alkalinity of surfaces to be coated exceeds that permitted in manufacturer's written instructions . <br /> 3 .3 APPLICATION <br /> A. Apply high-performance coatings according to manufacturer's written instructions . <br /> 1 . Use applicators and techniques suited for coating and substrate indicated. <br /> 2 . Coat surfaces behind movable equipment and furniture same as similar exposed surfaces . Before <br /> final installation, coat surfaces behind permanently fixed equipment or furniture with prime coat <br /> only. <br /> 3 . Coat back sides of access panels, removable or hinged covers, and similar hinged items to match <br /> exposed surfaces . <br /> Wabasso Beach Park Revised 01/08/08 <br /> Indian River County 09960 - 4 <br /> DAA Project No. 6008 <br />
