Comply also with applicable parts of ANSI A108/A118/A136.1 and manufacturer's recommendations. B. Patterns: Provide simple border and field patterns on floors and walls where noted in finish schedule using a maximum of three (3) different colors. C. Layout, Joining, and Fitting: 1. Extend tile work into recesses and under or behind equipment and fixtures to form a complete covering without interruptions, unless otherwise indicated. Terminate work neatly at obstructions, edges, and corners without disrupting pattern or joint alignments. 2. Accurately form intersections and returns. Perform cutting and drilling of tile without marring visible surfaces. 3. Carefully grind cut edges of tile abutting trim, finish, or built-in items for straight aligned joints. Fit tile closely to electrical outlets, piping, fixtures, and other penetrations so plates, collars, or covers overlap tile. Provide uniform joint widths. 4. Form internal angles square and external angles bull-nosed, unless otherwise noted 5. Lay tile in grid pattern, unless otherwise indicated. Lay out tile work and center tile fields in both directions. 5. Do not interrupt pattern through openings, unless otherwise noted. 6. Align floor joints to give straight uniform grout lines parallel with walls. Align joints between floor and base tile, and wall tile. Align joints in both directions. Create transitions to other material or colors under door, unless otherwise noted. D. General Installation Requirements: 1. Apply mortar or adhesive with notched trowel using scraping motion to work material into good contact with surface to be covered. Maintain 90 percent coverage on back of tile and fully bed all corners. 2. Apply only as much mortar or adhesive as can be covered within allowable windows as recommended by mortar or adhesive manufacturer or while surface is still tacky. 3. When installing large tiles, ceramics or mosaics, trowel small quantity of mortar or adhesive onto back of each tile or sheet of tiles. 4. Set tiles in place and rub or beat with small beating block. Beat or rap tile to ensure proper bond and also to level surface of tile. 5. Align tile to show uniform joints and allow to set until firm. 6. Clean excess mortar or adhesive from surface of tile with wet cheese cloth (not a sponge) while mortar is fresh. 7. Allow face mounted tile to set until firm before removing paper and before grouting. 8. Sound tile after setting. Replace hollow sounding tiles. E. Bonding Large Tile: 1. The following installation techniques are required to ensure proper coverage of the bonding surface of larger tiles and provide full support of edges and corners. Large tiles are generally considered to be 8 by 8 inch and greater. Use special specified mortar and a notched trowel sized to facilitate the proper coverage. 2. Key the mortar into the substrate with the flat side of the trowel. Comb with the notched side of the trowel in one direction. 3. Firmly press tiles into the mortar and move them perpendicularly across the ridges, forward and back approximately 1/8 to 1/4 inch to flatten the ridges and fill the valleys. 4. Periodically remove and check a tile to assure proper coverage is being attained. TILING
