Examine substrates and conditions, with Applicator present, for compliance with requirements <br />for maximum moisture content and other conditions affecting performance of work. <br />B. Maximum Moisture Content of Substrates: When measured with an electronic moisture meter <br />as follows: <br />1. Concrete: 12 percent. <br />2. Masonry (CMU): 12 percent. <br />3. Plaster: 12 percent. <br />C. Verify suitability of substrates, including surface conditions and compatibility with existing <br />finishes and primers. <br />D. Begin coating application only after unsatisfactory conditions have been corrected and surfaces <br />are dry. <br />1. Beginning coating application constitutes Contractor's acceptance of substrates and <br />conditions. <br />3.2 PREPARATION <br />A.

If removal is impractical or impossible because of size or weight of item, <br />provide surface -applied protection before surface preparation and painting. <br />1. After completing painting operations, use workers skilled in the trades involved to <br />reinstall items that were removed. Remove surface -applied protection. <br />C. Clean substrates of substances that could impair bond of paints, including dust, dirt, oil, grease, <br />and incompatible paints and encapsulants. <br />1. Remove incompatible primers and reprime substrate with compatible primers or apply tie <br />coat as required to produce paint systems indicated. <br />D. Concrete Substrates: Remove release agents, curing compounds, efflorescence, and chalk. Do <br />not paint surfaces if moisture content or alkalinity of surfaces to be painted exceeds that <br />permitted in manufacturer's written instructions. <br />E. Masonry Substrates: Remove efflorescence and chalk. Do not paint surfaces if moisture content <br />or alkalinity of surfaces or mortar joints exceeds that permitted in manufacturer's written <br />instructions. <br />EXTERIOR PAINTING 09 91 13 - 5 <br />
