LINOLEUM FLOOR COVERING <br />Section 09654 <br />15-1207 <br />finish. <br />Other materials: All other materials, including adhesives and cored base metal edge, not <br />specifically described but required for a complete and proper installation of flooring, shall be <br />only as recommended by the manufacturer of the material to which it is applied. <br />PART 3 - EXECUTION <br />3.01 INSPECTION <br />A. Prior to all work of this Section, carefully inspect the installed work of other trades and verify <br />that all work is complete to the point where this installation may properly commence. Work of <br />all other trades, including painting, shall be substantially completed before start of laying <br />flooring and permanent heating system must be in operation. <br />B. Verify that flooring and base may be installed in accord with the design, die lots are the same <br />and floors and walls will accept the adhesive and covering. <br />C. Examine substrate and conditions under which work is to be performed. Surfaces must be <br />broom -clean, free of coatings that would impair adhesion, smooth and level with no more than <br />1/8 inch in 10 feet variation from level. <br />D. Concrete Slab -On -Grade and Above -Grade Concrete Sub -Floor Testing: Flooring installer to <br />obtain Moisture/pH Testing results and acknowledge, in writing, that the report has been <br />received and approved. Installation of floor finishes may not begin without such review and <br />approval. <br />3.02 FLOOR PREPARATION <br />A. Subfloors shall be smooth, dry, repaired as necessary and clean of debris. Due to the nature <br />of concrete, the slab will not be completely smooth, flat or free of blemishes. Filling, patching <br />and leveling will be required. Smooth concrete surfaces, removing rough areas, projections, <br />ridges, and bumps, and filling low spots, control construction joints, and other defects with <br />underlayment and patch/skim coat as recommended by the flooring manufacturer. <br />B. Concrete Moisture Testing: Conduct moisture tests on all concrete floors regardless of the <br />age, grade level or the presence of existing flooring. Conduct calcium chloride tests in <br />accordance with ASTM F1869. Measure the internal relative humidity of the concrete slab in <br />accordance with ASTM F2170. One test of each type should be conducted for every 1,000 sq. <br />ft. of flooring. For projects less than 3,000 sq. ft., a minimum of three tests of each type should <br />be conducted. The tests should be conducted around the perimeter of the room, at columns, <br />and where moisture may be evident. Concrete moisture vapor emissions must not exceed 5.0 <br />lbs. per 1,000 sq. ft. in 24 hrs. Concrete internal relative humidity must not exceed 75%. A <br />diagram of the area showing the location and results of each test should be submitted to the <br />Architect, General Contractor or End User. If any test result exceeds these limitations, the <br />installation must not proceed until the problem has been corrected. <br />E. Concrete pH Test: Perform pH tests on concrete floors regardless of the age or grade level. If <br />the pH is greater than 10, it must be neutralized prior to beginning the installation. <br />F. Vacuum subfloors immediately prior to installation to remove loose particles. <br />5 <br />
