1 . Verify that substrates for setting tile are firm, dry, clean, free of coatings that are incompatible ` <br /> with tile-setting materials including curing compounds and other substances that contain soap, <br /> wax, oil, or silicone; and comply with flatness tolerances required by ANSI A108 .01 for <br /> installations indicated. <br /> 2 . Verify that joints and cracks in tile substrates are coordinated with tile joint locations; if not <br /> coordinated, adjust joint locations in consultation with Architect. <br /> B . Proceed with installation only after unsatisfactory conditions have been corrected. <br /> L <br /> 3 .2 PREPARATION <br /> 6 A. Blending : For tile exhibiting color variations, verify that tile has been factory blended and packaged so <br /> tile units taken from one package show same range of colors as those taken from other packages and <br /> match approved Samples . If not factory blended, either return to manufacturer or blend tiles at Project <br /> site before installing. <br /> B . Field-Applied Temporary Protective Coating: If indicated under tile type or needed to prevent grout from <br /> staining or adhering to exposed tile surfaces, precoat them with continuous film of temporary protective <br /> coating, taking care not to coat unexposed tile surfaces . <br /> 3 . 3 TILE INSTALLATION <br /> A. Comply with TCA's "Handbook for Ceramic Tile Installation" for TCA installation methods specified in <br /> the installation schedules . Comply with parts of the ANSI A108 Series " Specifications for Installation of <br /> Ceramic Tile " that are referenced in TCA installation methods, specified in tile installation schedules, and <br /> apply to types of setting and grouting materials used. <br /> 1 . For the following installations, follow procedures in the ANSI Al 08 Series of tile installation <br /> standards for providing 95 percent mortar coverage : <br /> i <br /> B . Extend tile work into recesses and under or behind equipment and fixtures to form complete covering <br /> without interruptions unless otherwise indicated. Terminate work neatly at obstructions , edges, and <br /> comers without disrupting pattern or joint alignments. <br /> C . Accurately form intersections and returns . Perform cutting and drilling of tile without marring visible <br /> surfaces . Carefully grind cut edges of tile abutting trim, finish, or built-in items for straight aligned <br /> joints. Fit tile closely to electrical outlets, piping, fixtures, and other penetrations so plates, collars, or <br /> covers overlap tile . <br /> D . Jointing Pattern: Lay tile in grid pattern unless otherwise indicated. Lay out tile work and center tile <br /> fields in both directions in each space or on each wall area. Lay out tile work to minimize the use of <br /> pieces that are less than half of a tile . Provide uniform joint widths unless otherwise indicated. <br /> E. Joint Widths : Unless otherwise indicated, install tile with the following joint widths : <br /> 1 . Glazed Wall Tile: 1 / 16 inch ( 1 . 6 mm) . <br /> F . Lay out tile wainscots to dimensions indicated or to next full tile beyond dimensions indicated. <br /> G. Expansion Joints : Provide expansion joints and other sealant-filled joints, including control, contraction, <br /> and isolation joints, where indicated. Form joints during installation of setting materials, mortar beds, <br /> and tile . Do not saw-cut joints after installing tiles. <br /> 1 . Where joints occur in concrete substrates, locate joints in tile surfaces directly above them. <br /> Wabasso Beach Park Revised 01/08/08 <br /> Indian River County 09310 - 6 <br /> DAA Project No. 6008 <br />
