Vinyl Composition Floor Tile Adhesives: Not more than 50 g/L. <br />C. Floor Polish: Provide protective liquid floor polish products as recommended by manufacturer. <br />D. Concrete Slab Primer: Non-staining type as recommended by flooring manufacturer. <br />PART 3 - EXECUTION <br />3.1 EXAMINATION <br />A. Examine substrates, with Installer present, for compliance with requirements for maximum moisture content and other <br />conditions affecting performance of the Work. <br />B. Verify that finishes of substrates comply with tolerances and other requirements specified in other Sections and that substrates <br />are free of cracks, ridges, depressions, scale, and foreign deposits that might interfere with adhesion of floor tile. <br />C. Proceed with installation only after unsatisfactory conditions have been corrected. <br />3.2 PREPARATION <br />A. Prepare substrates according to manufacturer’s written instructions to ensure adhesion of resilient products. <br />B. Concrete Substrates: Prepare according to ASTM F 710. <br />1. Verify that substrates are dry and free of curing compounds, sealers, and hardeners. <br />2. Remove substrate coatings and other substances that are incompatible with adhesives and that contain soap, wax, oil, <br />or silicone, using mechanical methods recommended by manufacturer. Do not use solvents. <br />3. Alkalinity and Adhesion Testing: Perform tests recommended by manufacturer. Proceed with installation only after <br />substrates pass testing. <br />4. Moisture Testing: Perform tests recommended by manufacturer. Proceed with installation only after substrates pass <br />testing. <br />a. Perform anhydrous calcium chloride test, ASTM F 1869. Proceed with installation only after substrates have <br />maximum moisture-vapor-emission rate of 3 lb of water/1000 sq. ft. in 24 hours. <br />b. Perform relative humidity test using in situ probes, ASTM F 2170. Proceed with installation only after <br />substrates have a maximum 75% relative humidity level measurement. <br />C. Fill cracks, holes, and depressions in substrates with trowelable leveling and patching compound and remove bumps and ridges <br />to produce a uniform and smooth substrate. <br />D. Do not install floor tiles until they are same temperature as space where they are to be installed. <br />1. Move resilient products and installation materials into spaces where they will be installed at least 48 hours in advance <br />of installation. <br />E. Sweep and vacuum clean substrates to be covered by resilient products immediately before installation. <br />F. Remove coatings, including curing compounds, and other substances that are incompatible with flooring adhesives and that <br />contain soap, wax, oil, or silicone, by using a terrazzo or concrete grinder, a drum sander, or a polishing machine equipped with <br />a heavy-duty wire brush. <br />G.
