Gateway Park Center PERKINS+WILL <br /> 810495.000 <br /> 12/06/18 <br /> <br /> <br />GLASS MOSAIC TILING <br /> 09 30 23 - 6 <br /> <br /> <br />3.2 PREPARATION <br />A. Blending: For tile exhibiting color variations, verify that tile has been factory <br />blended and packaged so tile units taken from one package show same range of <br />colors as those taken from other packages and match approved Samples. If not <br />factory blended, either return to manufacturer or blend tiles at Project site before <br />installing. <br />3.3 GLASS TILE INSTALLATION <br />A. Comply with TCNA's "Handbook for Ceramic, Glass, and Stone Tile Installation" for <br />TCNA installation methods specified in tile installation schedules. Comply with parts <br />of the ANSI A108 series "Specifications for Installation of Ceramic Tile" that are <br />referenced in TCNA installation methods, specified in tile installation schedules, and <br />apply to types of setting and grouting materials used. <br />B. Extend tile work into recesses and under or behind equipment and fixtures to form <br />complete covering without interruptions unless otherwise indicated. Terminate work <br />neatly at obstructions, edges, and corners without disrupting pattern or joint <br />alignments. <br />C. Accurately form intersections and returns. Perform cutting and drilling of tile <br />without marring visible surfaces. Carefully grind cut edges of tile abutting trim, <br />finish, or built-in items for straight aligned joints. Fit tile closely to electrical outlets, <br />piping, fixtures, and other penetrations so plates, collars, or covers overlap tile. <br />D. Where accent tile differs in thickness from field tile, vary setting -bed thickness so <br />that tiles are flush. <br />E. Jointing Pattern: Lay tile in grid pattern unless otherwise indicated. Lay out tile <br />work and center tile fields in both directions in each space or on each wall area. Lay <br />out tile work to minimize the use of pieces that are less than half of a tile. Provide <br />uniform joint widths unless otherwise indicated. <br />1. For tile mounted in sheets, make joints between tile sheets same width as <br />joints within tile sheets so joints between sheets are not apparent in finished <br />work. <br />F. Joint Widths: Unless otherwise indicated, install tile with the following joint widths: <br />1. Mosaic Glass Tile: 1/16 inch. <br />G. Lay out tile wainscots to dimensions indicated or to next full tile beyond dimensions <br />indicated. <br />H. Expansion Joints: Provide expansion joints and other sealant-filled joints, including <br />control, contraction, and isolation joints, where indicated. Form joints during <br />installation of setting materials, mortar beds, and tile. Do not saw-cut joints after <br />installing tiles. <br />1. Where joints occur in concrete substrates, locate joints in tile surfaces directly <br />above them.
