Verify that substrates are dry and free of curing compounds, sealers, and hardeners. <br />2. Alkalinity and Adhesion Testing: Perform tests recommended by manufacturer. Proceed <br />with installation only after substrates pass testing. <br />3. Moisture Testing: <br />a. Perform anhydrous calcium chloride test, ASTM F 1869. Proceed with installation <br />only after substrates have maximum moisture - vapor - emission rate of 3 lb of <br />water /1000 sq. ft. (1.36 kg of water /92.9 sq. m) in 24 hours. <br />b. Perform tests recommended by manufacturer. Proceed with installation only after <br />substrates pass testing. <br />C. Remove substrate coatings and other substances that are incompatible with adhesives and that <br />contain soap, wax, oil, or silicone, using mechanical methods recommended by manufacturer. <br />Do not use solvents. <br />D. Use trowelable leveling and patching compound to fill cracks, holes, and depressions in <br />substrates. <br />E. Move resilient products and installation materials into spaces where they will be installed at <br />least 48 hours in advance of installation. <br />1. Do not install resilient products until they are same temperature as space where they are <br />to be installed. <br />F. Sweep and vacuum clean substrates to be covered by resilient products immediately before <br />installation. After cleaning, examine substrates for moisture, alkaline salts, carbonation, and <br />dust. Proceed with installation only after unsatisfactory conditions have been corrected. <br />3.3 PLANK INSTALLATION <br />A. Lay out tiles from center marks established with principal walls, discounting minor offsets, so <br />tiles at opposite edges of room are of equal width. Adjust as necessary to avoid using cut <br />widths that equal less than one -half tile at perimeter. <br />1. Lay tiles square with room axis. <br />B. Match tiles for color and pattern by selecting tiles from cartons in the same sequence as <br />manufactured and packaged, if so numbered. Discard broken, cracked, chipped, or deformed <br />tiles. <br />1. Lay tiles with grain direction alternating in adjacent tiles (basket -weave pattern) in <br />pattern of colors and sizes indicated. <br />C. Scribe, cut, and fit tiles to butt neatly and tightly to vertical surfaces and permanent fixtures <br />including built -in furniture, cabinets, pipes, outlets, edgings, door frames, thresholds, and <br />nosings. <br />D. Extend tiles into toe spaces, door reveals, closets, and similar openings. <br />RESILIENT FLOOR TILE 096519-5 <br />
