Application
Wet the surface with water before applying the cementitious waterproofing to ensure optimum bonding. Apply DRYTEX CEM HB using a brush, roller, or spray equipment. For the best adhesion, it is recommended to apply the first coat with a brush. This waterproofing membrane features excellent high-build properties, allowing it to be applied up to 2000 microns wet in a single coat. However, for better curing, especially depending on weather conditions, it is advisable to apply and build up the membrane in two or more coats. Thicker applications will require a longer curing time.
