Fit tile closely to electrical outlets, piping, fixtures, and other <br /> penetrations so plates, collars, or covers overlap tile. <br /> D. Jointing Pattern: Lay tile in grid pattern unless otherwise indicated. Lay out tile work and center <br /> tile fields in both directions in each space or on each wall area. Lay out tile work to minimize <br /> the use of pieces that are less than half of a tile. Provide uniform joint widths unless otherwise <br /> indicated. <br /> 1> For tile mounted in sheets, make joints between tile sheets same width as joints within <br /> tile sheets so joints between sheets are not apparent in finished work. <br /> 2> Where adjoining tiles on floor, base, walls, or trim are specified or indicated to be same <br /> size, align joints. <br /> 3> Where tiles are specified or indicated to be whole integer multiples of adjoining tiles on <br /> floor,base,walls, or trim, align joints unless otherwise indicated. <br /> E. Joint Widths: Unless otherwise indicated, install tile with the following joint widths: <br /> 1> Porcelain and Ceramic Mosaic Tile: 1/16 inch(1.6 mm). <br /> 2> 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, <br /> contraction, and isolation joints, where indicated. Form joints during installation of setting <br /> materials,mortar beds, 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 <br /> them. <br /> 2> Prepare joints and apply sealants to comply with requirements in Division 07 Section <br /> "Joint Sealants." <br /> H. Stone Thresholds: Install stone thresholds in same type of setting bed as adjacent floor unless <br /> otherwise indicated. <br /> 1> At locations where mortar bed (thickset) would otherwise be exposed above adjacent <br /> floor finishes, set thresholds in latex-portland cement mortar(thin set). <br /> 2> Do not extend waterproofing or crack isolation membrane under thresholds set in dry-set <br /> portland cement or latex-portland cement mortar. Fill joints between such thresholds and <br /> adjoining tile set on waterproofing or crack isolation membrane with elastomeric sealant. <br /> 3> See detailed elevations on plans <br /> I. Metal Edge Strips: Install where exposed edge of tile flooring meets carpet, wood, or other <br /> flooring that finishes flush with top of tile. <br /> 3.4 TILE BACKING PANEL INSTALLATION <br /> A. Install cementitious backer units and fiber-cement underlayment and treat joints according to <br /> ANSI A108.11 and manufacturer's written instructions for type of application indicated. Use <br /> latex-portland cement mortar for bonding material unless otherwise directed in manufacturer's <br /> written instructions. <br /> TILING 093000 - 8 <br />
