Key specs: 18-liter bucket size; cement-sand blend with additives; non-shrinking formula; quick-drying for faster repairs; suitable for interior and exterior applications; applications via trowel, brush, or roller; adheres well to bricks, stone, and similar surfaces; ready-to-use for convenient repairs.

It’s designed for interior and exterior stucco repairs on walls and other vertical surfaces. Use it to fill cracks, holes, and imperfections on stucco, brick, stone, and similar substrates for a smooth, uniform finish.

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.
