Application steps

SUBSTRATE PREPARATION

For best results, the temperature of the substrate or tile must be between 40°F and 95°F (4°C and 35°C) while applying caulk. For proper curing, maintain this temperature range for 72 hours after application. Before applying caulk, make sure that the tiles or stones are firmly set and that the adhesive or mortar is completely dry. Joints must be clean and free of standing water, dust, dirt, and foreign matter. Clean the tile or stone surface to remove dust, dirt, mortar, adhesive, and other contaminants that may cause discoloration.
