Substrate priming: Diluted Dysperbit should be applied with of a paint brush or a roofing brush to a properly prepared surface.

Damp-proof coatings: It is recommended to apply the Dysperbit to the primed surface. The successive layer can be applied after the previous one has fully dried. The total thickness of a dry layer should be at least 1 mm. Material should be applied by hand, using a brush or a roofing brush. The freshly applied coating must be protected from strong sunlight (e.g. by shading), flooding, rain and negative temperatures. After complete bonding, the waterproof coating should be protected against mechanical damage associated with backfilling the excavation.

Maintenance of felt coverings: After filling in the defects and full drying of the compound, apply Dysperbit to the whole surface of the roof covering in two layers, applying each after the previous one has dried. In areas where the roof slopes meets the chimney, at ducts and ventilation pipes etc. use reinforcement by embedding a reinforcing fabric and turning it up to the appropriate height. The last, still fresh layer, is recommended to be sprinkled with a mineral topping.
