4 E. Other materials, including edge strips not specifically described, but required for a complete and proper installation of Resilient Sport Flooring, shall be only as recommended by the manufacturer of material to which it is applied. PART 3 EXECUTION 3.01 INSPECTION: A. Installer must examine the areas and conditions under which resilient flooring and accessories are to be installed and notify the Contractor in writing of conditions detrimental to the proper and timely completion of the work. Do not proceed with the work until unsatisfactory conditions have been corrected in a manner acceptable to the Installer. REVISED: 05/01/13 1. Visually inspect for evidence of moisture, alkaline salts, carbonation, dusting, mold, or mildew. 2. Failure to call attention to defects or imperfections will be construed as acceptance and approval of the subfloor. Installation indicates acceptance of substrates with regard to conditions existing at the time of installation PREPARATION A. General: Comply with manufacturer's installation specifications for preparing substrates to receive products indicated. B. Sweep and vacuum clean substrates to be covered by floor coverings immediately before installation. After cleaning, examine substrates for moisture, alkaline salts, carbonation, and dust. Proceed with installation only after unsatisfactory conditions have been corrected. C. This Contractor to remove coatings, including curing compounds, adhesives, plastics, and other substances that are incompatible with flooring adhesives and that contain soap, wax, oil, or silicone, by using a terrazzo or concrete grinder, a drum sander, or a polishing machine equipped with a heavy-duty wire brush. Surface to receive new flooring shall be prepared, including removal of existing materials not acceptable for proper installation of new materials, as required by manufacturer. Do not use solvents. 1. Prep floor according to ASTM F710 criteria. D. Use leveling compound as recommended by flooring manufacturer for filling small cracks and depressions in subfloors. E. Apply concrete slab primer, if recommended by flooring manufacturer, prior to application of adhesive. Apply in compliance with manufacturer's directions CONCRETE SUBFLOORS A. Concrete subfloors to be placed a minimum of twenty-eight (28) days prior to the installation of rubber athletic flooring. B. Verify that concrete slabs comply with ASTM F710 and the following: 1. Slab substrates are dry and free of curing compounds, sealers, hardeners, residual adhesives, adhesive removers, and other materials whose presence would interfere with bonding of adhesive. Determine adhesion and dryness characteristics by performing bond and moisture tests recommended by manufacturer. 2. Finishes of subfloors comply with tolerances and other requirements specified in Division 03 Section, "Cast-In-Place Concrete" for slabs receiving resilient flooring. 3. Subfloor Moisture Conditions: Before installing flooring Contractor shall verify that Moisture emission rate of not more than 3 lb/1000 sq. ft./24 hours when tested by calcium chloride moisture test in compliance with CRI 104, and does not exceed the PAGE 4 FILE: CFRT-Resilient Athletic Flooring.doc CFRST SPECMSTR-NEW BUILD 2013, Marriott International, Inc.

Maintain overall continuity of color and pattern with pieces of flooring installed in these covers. Tightly cement edges to perimeter of floor around covers and to covers. G. Tightly cement flooring to subbase without open cracks, voids, raising and puckering at joints, telegraphing of adhesive spreader marks, or other surface imperfections CLEANING AND PROTECTION A. Perform the following operations immediately after installing resilient floor coverings: 1. Remove adhesive and other surface blemishes using cleaner recommended by floor covering manufacturer. 2. Sweep or vacuum floor thoroughly. 3. Do not wash floor covering until after time period recommended by floor covering manufacturer. a.
