Proceed with <br />installation only after substrate alkalinity falls within range on pH scale recommended by <br />manufacturer in writing. <br />4.Moisture Testing: Proceed with installation only after substrates pass testing according to <br />manufacturer's written recommendations, but not less stringent than the following: <br />a.Perform anhydrous calcium chloride test according to ASTM F 1869. Proceed with <br />installation only after substrates have maximum moisture-vapor-emission rate of 3 lb of <br />water/1000 sq. ft. in 24 hours. <br />b.Perform relative humidity test using in situ probes according to ASTM F 2170. Proceed <br />with installation only after substrates have maximum 60 percent relative humidity level. <br />C.Fill cracks, holes, and depressions in substrates with trowelable leveling and patching compound; <br />remove bumps and ridges to produce a uniform and smooth substrate. <br />D.Do not install resilient products until they are the same temperature as the space where they are to be <br />installed. <br />1.At least 48 hours in advance of installation, move resilient products and installation materials <br />into spaces where they will be installed. <br />E.Immediately before installation, sweep and vacuum clean substrates to be covered by resilient <br />products. <br />3.3 RESILIENT BASE INSTALLATION <br />A.Comply with manufacturer's written instructions for installing resilient base. <br />B.Apply resilient base to walls, columns, pilasters, casework and cabinets in toe spaces, and other <br />permanent fixtures in rooms and areas where base is required.
