Resilient Molding Accessory: <br />1. Manufacturers: Subject to compliance with requirements, provide products by one of the following: <br />a. Burke Mercer Flooring Products; Division of Burke Industries, Inc. <br />b. Flexco, Inc. <br />c. Johnsonite. <br />d. Roppe Corporation, USA. <br />e. VPI, LLC; Floor Products Division. <br />B. Description: Edge for glue-down applications, Reducer strip for resilient floor covering, Transition strips. <br />C. Material: Rubber. <br />D. Rubber transition strips with profile designed to protect tile edges and allow for a smooth transition between <br />floor coverings at lower elevations or abutting surfaces. <br />E. Provide profile and dimensions suitable for floor finish, thickness of tile, and floor material transition.: <br />1. Rubber profile that transitions from Carpet to Luxury Vinyl Tile. <br />2. Rubber profile that transitions from Luxury Vinyl Tile to Athletic Flooring. <br />3. Rubber profile that transitions from Sealed Concrete to Luxury Vinyl Flooring. <br />F. Colors and Patterns: As selected by Architect from full range of industry colors. <br /> <br /> <br />2.5 INSTALLATION MATERIALS <br /> <br />A. Trowelable Leveling and Patching Compounds: Latex-modified, portland-cement-based or blended <br />hydraulic-cement-based formulation provided or approved by resilient-product manufacturer for <br />applications indicated. <br /> <br />B. Adhesives: Water-resistant type recommended by resilient-product manufacturer for resilient products <br />and substrate conditions indicated. <br /> <br /> <br />PART 3 - EXECUTION <br /> <br />3.1 PREPARATION <br /> <br />A. Prepare substrates according to manufacturer's written instructions to ensure adhesion of resilient <br />products. <br /> <br />B. Concrete Substrates: Prepare horizontal surfaces according to ASTM F710. <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 <br />contain soap, wax, oil, or silicone, using mechanical methods recommended by manufacturer. Do <br />not use solvents. <br />3. Alkalinity and Adhesion Testing: Perform tests recommended by manufacturer. Proceed with <br />installation only after substrate alkalinity falls within range on pH scale recommended by <br />manufacturer in writing, but not less than 5 or more than 9 pH. <br />4. Moisture Testing: Perform tests so that each test area does not exceed 1000 sq. ft., and perform no <br />fewer than three tests in each installation area and with test areas evenly spaced in installation areas. <br />a. Anhydrous Calcium Chloride Test: ASTM F1869. Proceed with installation only after <br />substrates have maximum moisture-vapor-emission rate of 3 lb of water/1000 sq. ft. in 24 <br />hours. <br />b. Relative Humidity Test: Using in-situ probes, ASTM F2170. Proceed with installation only <br />after substrates have a maximum 75 percent relative humidity level measurement. <br /> <br />C. Fill cracks, holes, and depressions in substrates with trowelable leveling and patching compound; remove <br />bumps and ridges to produce a uniform and smooth substrate. <br /> <br />D. Do not install resilient products until materials are the same temperature as space where they are to be <br />Docusign Envelope ID: 52FACC74-DA96-491B-B0B8-04AC3961737D
