Application instructions

1. Surface preparation: Ensure the surface is clean, dry, and free of dust. The temperature should be above +5°C and the humidity below 80%. Glossy surfaces should be sanded, shiny surfaces should be cleaned and primed.
2. Application: Apply with a steel spatula. For thicker layers, apply in several coats, allowing each to dry.

Recommendations

After drying, the surface can be treated with water-resistant paints (e.g. KRASO PROJEKT 7 Aqua). Use a waterproofing membrane for tiling. Wear protective goggles and a mask when sanding. Ensure good ventilation. Protect from frost.
