PART 2 - PRODUCTS See Product Specification page. PART 3 - EXECUTION 3.01 EXAMINATION A. Verify that spaces to receive resilient flooring are suitable for installation. Do not proceed with work until unsatisfactory conditions are corrected. Comply with manufacturer's recommendations including the following: 1. Substrates shall be dry and clean. 2. Substrates shall be free of depressions, raised areas, or other defects which would telegraph through installed flooring. 3. Temperature of resilient flooring and substrate shall be within specified tolerances. 4. Moisture condition and adhesive bond tests shall be performed as specified. B. For applications on concrete, verify curing, hardening, or breaking compounds have not been used. If there are any, do not proceed until compounds have been removed as specified. C. For applications on concrete slab on grade or below grade, verify vapor barrier below slab was installed. If no vapor barrier was installed, do not proceed with work unless written acceptance of such conditions is received and submitted. D. Perform moisture condition test in each major area, minimum 1 per 2,000 square feet, prior to installation. Moisture condition shall not exceed 3 pounds per 1,000 square feet per 24 hour day, in accordance with Rubber Manufacturers Association Test Method. Do not proceed with work until results of moisture condition tests are acceptable. E. Perform adhesive bond test in each major area, minimum 1 per 2,000 square feet, prior to installation. Examine after 72 hours to determine whether bond is solid and no moisture is present. Do not proceed with work until results of bond test are acceptable. 3.02 PREPARATION A. Comply with ASTM F 710-92 and manufacturer's recommendations for surface preparation. Remove substances incompatible with resilient flooring adhesive by method acceptable to manufacturer. 1.

Do not mix manufacturing batches of a color within the same area. 8. Do not install resilient flooring over building expansion joints. 9. Do not install defective or damaged resilient flooring. B. Install resilient wall base in accordance with manufacturer's printed installation instructions. Install in longest practical lengths. Tightly adhere to substrate. Fill voids due to seams in substrate materials with manufacturer's recommended filler material. C. Install resilient stairtreads and accessories in accordance with manufacturer's printed installation instructions. Install reducer strips at exposed edges. Tightly adhere to substrate only where recommended by manufacturer. Fill voids due to seams in substrate materials with manufacturer's recommended filler material. D. NORAPLAN SEAMLESS FLOORING INSTALLATION (WHEN REQUIRED). Rout seams and heat weld together with coordinated colored heat welding rod in accordance with resilient flooring manufacturer's recommendations. E. NORAMENT SEAMLESS FLOORING INSTALLATION (WHEN REQUIRED). Rout seams and weld together with coordinated colored cold weld compound in accordance with resilient flooring manufacturer's recommendations. F. FLASH COVING OF SHEET GOOD (WHEN REQUIRED). Extend flooring up the wall in a flash-coved method to a height as indicated. Provide cove stick and manufacturer's recommended clip-on cap piece. Follow resilient flooring manufacturer's flash-coving instructions. 3.04 CLEANING AND PROTECTION A. Touch-up and repair minor damage to eliminate all evidence of repair. Remove and replace work which cannot be satisfactorily repaired. B. Clean surfaces only after adhesive has fully cured, no sooner than 72 hours after installation. Clean surfaces using non-abrasive materials and methods recommended by manufacturer. Remove and replace work that cannot be successfully cleaned. C.
