Bostik Cempolay Deep is a protein-free, high-strength, high-performance deep self-levelling compound based on a blend of cements and organic binders.

The versatility of Bostik Cempolay Deep allows for application between 5-50mm thicknesses in a single-use.

Bostik Cempolay Deep is ideal for smoothing/levelling concrete, sand/cement screeds and unglazed ceramic tiles. It is also suitable for filling uneven floors and forming sloping screeds. However, this product is not suitable for use on mastic asphalt.
