Round 1 Bowling and Amusement 12/09/2024 Paradigm Design <br />RESILIENT TILE FLOORING 09 6519 - 5 <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 <br />that contain soap, wax, oil, or silicone, using mechanical methods recommended by floor <br />tile manufacturer. Do not use solvents. <br />3. Alkalinity and Adhesion Testing: Perform tests recommended by floor tile manufacturer. <br />Proceed with installation only after substrate alkalinity falls within range on pH scale <br />recommended by manufacturer in writing, but not less than 5 or more than 10 pH. <br />4. Moisture Testing: Proceed with installation only after substrates pass testing according to <br />floor tile manufacturer's written recommendations, but not less stringent than the <br />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 <br />lb of water/1000 sq. ft. in 24 hours. <br />b. Perform relative humidity test using in situ probes according to ASTM F 2170. <br />Proceed with installation only after substrates have a maximum 75 percent relative <br />humidity level. <br />C. Access Flooring Panels: Remove protective film of oil or other coating using method <br />recommended by access flooring manufacturer. <br />D. Fill cracks, holes, and depressions in substrates with trowelable leveling and patching <br />compound; remove bumps and ridges to produce a uniform and smooth substrate. <br />E. Do not install floor tiles 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 floor tile and installation <br />materials into spaces where they will be installed. <br />F. Immediately before installation, sweep and vacuum clean substrates to be covered by resilient <br />floor tile. <br />3.3 FLOOR TILE INSTALLATION <br />A. Comply with manufacturer's written instructions for installing floor tile. <br />B. Lay out floor tiles from center marks established with principal walls, discounting minor <br />offsets, so tiles at opposite edges of room are of equal width. Adjust as necessary to avoid using <br />cut widths that equal less than one-half tile at perimeter. <br />1. Lay tiles square with room axis or in pattern indicated. <br />C. Match floor 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.
