Porcelain tile can have large variances in sizing. Do not mix sizes and types of tiles in <br />pattern areas. Joints that do not line up or joint widths that vary will be unacceptable. <br />1. Joint Width: 1/4 inch wide, unless otherwise recommended. <br /> <br />3.4 MIXING MORTARS AND GROUT <br /> <br />A. Proportion mixes in accordance with latest ANSI standard specifications. <br /> <br />B. Mix mortars and grouts to comply with referenced standards and mortar and grout <br />manufacturers' written instructions using mixing equipment designed for optimum <br />performance characteristics for installations indicated. <br /> <br />C. Add materials, water, and additives in accurate proportions according to <br />manufacturer’s written instructions. <br /> <br />1. Liquid latex additive shall be added undiluted. <br /> <br />3.5 SETTING METHODS <br /> <br />A. Comply with parts of ANSI A108 series of tile installation standards in "Specifications <br />for Installation of Ceramic Tile" that apply to types of setting and grouting materials <br />and to methods indicated in ceramic tile installation schedules. <br /> <br />B. Install floor tile, thresholds and base in accordance with Tile Council of North America <br />recommendations. <br /> <br />C. All areas must have a cleavage membrane installed under 100 percent of tiled floor <br />area. Areas receiving a shower pan or waterproofing membrane are excluded. <br /> <br />D. Concrete Subfloors <br /> <br />1. LHT Mortar Bed Method: Latex-Portland cement mortar bond coat using the <br />mortar bed to assist in filling the irregular space between the tile and the <br />underlayment, ANSI 118.15. <br /> <br />E. Sound each tile after set. Replace all tiles sounding hollow. <br /> <br />3.6 INSTALLATION, GENERAL <br /> <br />A. Perform cutting and drilling of tile without marring visible surfaces. Grind cut edges of <br />tile abutting trim, finish, or built-in items for straight aligned joints. Fit tile to electrical <br />outlets, piping, fixtures, and other penetrations so plates, collars, or covers overlap <br />tile. <br />1. Smooth exposed cut edges. <br /> <br />B. Extend tile work into recesses and under or behind equipment and fixtures. Terminate <br />work at obstructions, edges, and corners without disrupting pattern or joint <br />alignments.
