Solvent-Based Bitumen Coating Mastic Den Braven Den Bit-D (11 kg)

Den Braven Den Bit-D is a ready-to-use solvent-based bitumen waterproofing compound, medium-modified with synthetic rubber, resins, and specialized chemical additives. The product features excellent adhesion to various substrate types and is engineered for medium-duty waterproofing installations, as well as the repair and conservation of roofing surfaces.

The compound effectively penetrates the structure of old roofing felt, restoring its elasticity and protective performance. The mastic is formulated exclusively for outdoor applications or ventilated sections of underground structures (foundations, underground building elements, industrial water tank bottoms) and is strictly incompatible with expanded polystyrene (EPS).

Design and Performance Features:

• Elasticity and Substrate Bonding: Rubber and resin modification ensures the formation of a durable, highly flexible coating that bonds strongly to mineral and bitumen substrates.
• Movement Accommodation: The cured layer successfully accommodates minor substrate shifting and bridges structural microcracks.
• Application Versatility: Suitable for application on completely dry as well as slightly damp surfaces (free of standing water).
• Chemical and Water Resistance: The formed coating delivers complete resistance to water, weathering, weak acids, and alkalis.
