ENVS 10003 CONSTRUCTION LOG BOOK Floors Ceramic Tile -Small, modular surfacing units made or clay or other composite materials -Durable, tough, dense -Good in compression -Extremely weak in tension -Glazed or unglazed -In application, a cleavage membrane isolated the mortar bed from damaged or unsuitable backings and allows independent movement of the supporting structure to occur

Adhesion process: Thin-set • Tile is bonded to a continuous, stable backing with a thin coat of dry set mortar, latex-Portland, epoxy or organic adhesive • Wet areas require fiberglass backing • Floors suitable are concrete and double wood Adhesion process: Thick-set • Tile is applied over a thick bed of mortar • This allows the natural curvature of the surface to be retained • Mortar bed is also not affected by prolonged contact with water • Suitable beds include cured concrete, plywood
