Solvent-Based Bitumen Primer Den Braven Den Bit-R (11 kg)

Den Braven Den Bit-R is a ready-to-use elastic bitumen compound based on organic solvents, modified with synthetic rubber and containing special chemical additives. The product features high penetrating capacity and is designed for high-quality priming of concrete and bitumen substrates prior to applying main waterproofing coatings or laying heat-weldable roofing felt. Additionally, the formulation can be utilized as a standalone seamless light moisture-proof waterproofing coating for roofs, foundations, and tanks.

Due to its engineered composition, the primer effectively bridges substrate microcracks and creates a reliable adhesion layer. The product is intended exclusively for outdoor applications or ventilated sections of underground structures, ensuring long-term protection of building components.

Design and Performance Features:

• Deep Penetration: Special additives ensure deep penetration of the material into the structure of mineral substrates.
• High Elasticity: Modification with synthetic rubber allows the cured layer to maintain stable elasticity and compensate for substrate micro-deformations.
• Application Versatility: The compound is formulated for effective application on both dry and slightly damp surfaces.
• Chemical Resistance: The formed film is highly resistant to water, weak acids, and alkalis.
• Material Restriction: The product is strictly forbidden for use in areas of direct contact with expanded polystyrene (EPS).
