K-Rend Silicone Top Coat K1 25kg

Silicone K1 is specifically designed to incorporate the benefits of silicone water repellents into a cement-based render system with an attractive, low maintenance finish.

K-Rend K1 Silicone adds a high water repellent quality, while allowing water vapour to pass freely through the render.

The amount of dirt adhering to the surface is greatly reduced, ensuring a freshly rendered appearance for a prolonged period of time.

This dry surface also improves the resistance of the finished render to algae growth and the natural phenomenon of lime-bloom.

Silicone K1 K-Rend is normally applied in two passes depending on background conditions and final finish required.

Use an 8mm or 14mm diameter spray nozzle according to the finish required.
