3.02 SURFACE PREPARATION: Tile flooring shall be in a smooth, true, level plane, except where indicated as sloped. Before any work under this Section is begun, all defects such as rough or scaling concrete, low spots, high spots, and uneven surfaces shall have been corrected, and all damaged portions of concrete slabs shall have been repaired as recommended by the flooring manufacturer.

Concrete curing compounds, other than the type that does not adversely affect adhesion, shall be entirely removed from the slabs. Paint, varnish, oils, release agents, sealers, waxes, and adhesives shall be removed, as recommended by the flooring manufacturer.

A. Concrete Floor: Grind ridges and other uneven surfaces smooth. Cut out and fill cracks 1/16 inch or wider with crack filler. Provide mastic underlayment to fill remaining holes, cracks, and depressions and for smoothing, leveling, or creating a feather edge in accordance with instructions of mastic manufacturer. After cleaning and removal of loose particles, prime chalky or dusty surfaces with primer recommended by flooring manufacturer.

B. Final Cleaning of Substrate: Clean substrate with broom or vacuum immediately prior to the installation of flooring.

3.03 MOISTURE TEST: The suitability of the concrete subfloor for receiving the resilient tile flooring with regard to moisture content shall be determined by spreading 6-inch square patch of adhesive in each 150 square foot area to receive vinyl tile flooring, and allowing it to dry overnight. If latex-based underlayment has been used, test patches shall include areas covered with underlayment. If the set adhesive can be scraped easily from floor surfaces, floor is not sufficiently dry. Repeat test until adhesive adheres properly. When adhesive adheres tightly to floor surface, proceed with installation.

3.04 GENERAL APPLICATION REQUIREMENTS: To avoid damage, install flooring after other work in same area has been completed. Apply flooring and accessories in accordance with manufacturer's directions, using experienced workers. Detailed requirements follow:

A. Adhesives: Do not allow smoking, open flames or other sources of ignition in area where solvent-containing adhesives are being used or spread, after posting conspicuous signs reading "NO

SMOKING OR OPEN FLAME".

B. Flooring: Apply in patterns indicated. Start in center of room or area, and work toward edges.

Keep tile lines and joints square, symmetrical, tight, and even. Keep each floor in true, level plane, except where slope is indicated. Vary width of edge tiles as necessary to maintain full-size tiles in field, but no edge tile shall be less than one-half full size, except where irregular-shape makes it impossible.

C. Cutting: Cut flooring edges and scribe to walls and partitions after field flooring has been applied.

D. Edge Strips: Provide edging strips where flooring terminates at points higher than contiguous finished flooring, except where thresholds are provided. Anchor metal strips to concrete floor surfaces by countersunk screws into metal or fiber expansion sleeves. Secure plastic strips with adhesive.

3.05 INSTALLATION OF VINYL COMPOSITION TILE: Tile flooring shall be installed with adhesive in accordance with the manufacturer's installation instructions. Tile lines and joints shall be kept square, symmetrical, tight, and even. Edge width shall vary as necessary to maintain full-size tiles in the field, but no edge tile shall be less than one-half the field tile size, except where irregular shaped rooms make it impossible. Flooring shall be cut to, and fitted around, all permanent fixtures, built-in furniture and cabinets, pipes, and outlets. Edge tile shall be cut, fitted, and scribed to walls and partitions after field flooring has been applied.

Edge strips shall be provided at locations where flooring termination is higher than the adjacent finished flooring, except at doorways where thresholds are provided. At doors, locate edge strip under door centerline. Anchor metal strips to concrete floor surfaces with countersunk screws in metal or fiber expansion sleeves.

3.07 INSTALLATION OF WALL BASE: Wall base shall be installed with adhesive in accordance with the manufacturer's written instructions. Base joints shall be tight and base shall be even with adjacent resilient tile flooring. Voids along the top edge of base at walls shall be filled with caulk. Roll entire vertical surface of base with hand roller, and press toe of base with a straight piece of wood to ensure proper alignment. Avoid excess adhesive in corners.

3.08 CLEANING: Immediately upon completion of installation of tile in a room or an area, flooring and adjacent surfaces shall be dry-cleaned to remove all surplus adhesive. No sooner than five (5) days after installation, flooring shall be washed with a nonalkaline cleaning solution, rinsed thoroughly with clear cold water and given two coats of polish in accordance with manufacturers written instructions.

3.09 PROTECTION: From the time of laying until acceptance, tile flooring shall be protected from damage as recommended by the flooring manufacturer. Flooring which becomes damaged, loose, broken, or curled and cove base which is not tight to backing fillet shall be removed and replaced.
