Gateway Park Center PERKINS+WILL <br /> 810495.000 <br /> 12/06/18 <br /> <br /> <br />CERAMIC TILING <br /> 09 30 13 - 7 <br /> <br /> <br />a. Tile floors in wet areas. <br />b. Tile floors consisting of tiles 8 by 8 inches or larger. <br />c. Tile floors consisting of rib-backed tiles. <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 penet rations so plates, collars, or covers overlap tile. <br />D. Provide manufacturer's standard trim shapes where necessary to eliminate exposed <br />tile edges. <br />E. Where accent tile differs in thickness from field tile, vary setting bed thickness so <br />that tiles are flush. <br />F. 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 />G. Joint Widths: Unless otherwise indicated, install tile with the following joint widths: <br />1. Porcelain Tile: As indicated. <br />H. Lay out tile wainscots to dimensions indicated or to next full tile beyond dimensions <br />indicated. <br />I. 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. <br />J. Stone Thresholds: Install stone thresholds in same type of setting bed as adjacent <br />floor unless otherwise indicated. <br />1. At locations where mortar bed (thickset) would otherwise be exposed above <br />adjacent floor finishes, set thresholds in modified dry-set mortar (thinset). <br />2. Do not extend waterproofing or crack isolation membrane under thresholds <br />set in modified dry-set mortar. Fill joints between such thresholds and <br />adjoining tile set on waterproofing or crack isolation membrane with <br />elastomeric sealant. <br />K. Metal Edge Strips: Install at locations indicated and where exposed edge of tile <br />flooring meets carpet or other flooring that finishes flush with or below top of tile <br />and no threshold is indicated.
