Suitable Substrates

Suitable backings, when properly prepared, include plumb and true masonry concrete, gypsum board (dry interior walls only), glass mesh mortar units, cured Portland cement beds, ceramic tile, and marble.

General Surface Prep

All floors must be structurally sound, free of frost, and in an atmosphere above freezing during the initial cure (72 hours). Concrete and other cementitious substrate floors must be dry and free of dirt, and other foreign matter. Cleaning may be accomplished via mechanical sanding, scraping or chipping. Surfaces should be further cleaned by acid washing using a 10% solution of muriatic acid. It is important that the acid sludge is thoroughly flushed with water.

Use NIOSH approved dust mask for silica dust. Contains Portland cement. If any cement or cement mixture gets into eyes, flush immediately and repeatedly with water, and consult physician promptly. Fresh mixed cement, mortar, concrete, or grout may cause skin injury. Avoid contact with skin where possible and wash exposed skin areas promptly with water. KEEP OUT OF REACH OF CHILDREN.
