CHAPEL HILL ORANGE COUNTY VISITORS BUREAU August 12, 2020 <br />308 WEST FRANKLIN, CHAPEL HILL, NC <br /> <br />TILING 093000 - 8 <br />straight aligned joints. 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 />DocuSign Envelope ID: 775B89AF-3514-4D9E-B148-2FDE4EFF16C2
