Ensure tile joints are uniform in width, subject to normal variance in tolerance allowed <br />in tile size. Ensure joints are watertight, without voids, cracks, excess mortar or grout. <br /> <br />D. Locate expansion, control, contraction, and isolation joints, during installation of <br />setting materials, mortar beds, and tile. Do not saw-cut joints after installing tiles. <br />1. Locate joints in tile surfaces directly above joints in concrete substrates. <br />2. Prepare joints and apply sealants to comply with requirements of Division 07 <br />Section, Joint Protection. <br />3. Isolated repaired structural cracks and shrinkage per TCNA Detail F125. <br /> <br />E. Allow tile to set for a minimum of 48 hours prior to grouting. Follow manufacturer’s <br />directions if longer waiting period is required. <br /> <br />F. Curing: <br />1. Flattening Beds: Moist cure for 20 hours at minimum 70° F for dry-set mortar <br />installations. Allow to dry before setting tile. Environmental conditions and <br />manufacturer may require longer cure times. <br />2. Dry-set Mortar: Minimum 48 hours, longer depending on temperature, humidity, <br />and manufacturer recommendations. <br />3. Dry-set Grout: Damp cure minimum 72 hours, longer depending on <br />temperature, humidity, and manufacturer recommendations. <br /> <br />3.7 GROUTING <br /> <br />A. Install grouting in accordance with ANSI A108.10 and manufacturer's written <br />instructions during application and cleaning. <br /> <br />B. Rinse tile work with clean water before and after using chemical cleaners. <br /> <br />3.8 CLEANING AND PROTECTING <br /> <br />A. Clean tile and grout as recommended by manufacturer. Remove all traces of grout. <br /> <br />B. Cover exposed hardware with a heavy coating of Vaseline to protect the metal from <br />the possible effects of the acid or its fumes, when acid solutions are recommended by <br />manufacturer to clean the face of finished tile work of surplus grouting or pointing <br />mortar. Do not use acid solution for cleaning glazed tile. <br /> <br />C. Protect the tile against damage after installation. Damaged tile that appears in the <br />finish work prior to the data of Substantial Completion is to be repaired or replaced. <br />Protect adjoining areas and surfaces. <br /> <br /> <br />END OF SECTION
