1) Clean the surface and remove dust or loose material. 2) If needed, slightly dampen very porous areas. 3) Apply the filler with a trowel, brush, or roller, pressing into cracks and holes. 4) Build up in thin layers as required and smooth the finish. 5) Allow each layer to set; lightly sand if needed once dry. 6) Clean tools with water before the material hardens.

In most cases, a clean, sound surface is sufficient. If the surface is very porous, dusty, or severely degraded, a dampening step or primer may help improve adhesion. Always follow the product guidelines for best results.

Wear gloves and eye protection. Work in a well-ventilated area and avoid skin contact with the wet material. If contact occurs, wash with soap and water. Keep out of reach of children, and store the product in a cool, dry place. Clean tools with water while the product is still wet.

The filler dries quickly to a smooth finish. Drying and full curing depend on temperature and humidity. In typical conditions, you can expect a usable surface within hours and full curing over 24–48 hours.
