The installation of the Johnsonite Power Tape Adhesive System and the flooring products should not begin until the work of all other trades has been completed, especially overhead trades. Areas to receive flooring products shall be clean, fully enclosed, weathertight, and maintained at a uniform temperature of at least 700 F for 24 hours before, during, and after the installation is completed. The flooring products and the Power Tape shall be conditioned in the same manner. Wood floors should be double construction with a minimum thickness of 1 inch. Material selection shall be made utilizing ASTM F 1482, Standard Guide to Wood Underlayments Available for Use Under Resilient Floors. "Particle or chipboard" type underlayments are not acceptable. The floor must be rigid, free of movement, and have at least 18" of well ventilated air space below. Concrete shall be prepared utilizing ASTM F 710-86, Practice for Preparing Concrete Floors and other Monolithic Floors to Receive Resilient Flooring. The floor and stair surfaces shall be smooth, flat to within 1/8” in 10 ft., permanently dry, clean and free of all foreign material, such as dust, paint, grease, oils, solvents, curing and hardening compounds, sealers, asphalt, and old adhesive residue. It is essential that moisture tests be taken on all concrete floors regardless of age and grade level. The test shall be in accordance with ASTM F-1869 Standard Test Method for Measuring Moisture Vapor Emission Rate of Concrete Subfloor Using Anhydrous Calcium Chloride. One test should be conducted for every 1000 sq. ft. of flooring and the results not exceed 3 lbs. per 1000 sq. ft. in 24 hours. If the test results exceed the limitations, the installation must not proceed until the problem has been corrected. Do not install on exterior surfaces subject to weather. Do not install flooring products over expansion joints. Cracks and uneven surfaces shall be filled with a quality cementitious patching compound. Apply the Power Tape to the back of the flooring product and install as indicated in the specific Power Tape installation instructions for the product. All flooring products shall be rolled, with a J-hand roller, after installation, to ensure proper bonding.
