Den Braven DenBit BR-ALP Asfalt Primer Coating, 4.5 kg

It is an elastic bitumen material slightly modified with synthetic rubber, containing chemical additives that allow for deep penetration and use on moderately damp substrates. This primer coating is capable of leveling micro-cracks in the substrate. The coating is resistant to water, weak acids, and alkalis.

Type of substrate:
Concrete, plasters, masonry, eternit, steel and metal elements (roofs, cladding, conduits and penetrations), bitumen-based materials, wooden substrates and substrates based on wood (cement-bonded and gypsum-fiber boards, OSB boards, etc.).

Use:
As a solution intended for the priming of foundation strips, foundations, underground parts of buildings, etc. The material is especially suitable as a substrate for thermally weldable membranes of all kinds. It is used under waterproof coatings from DenBit DK-ATN and other coatings based on organic asphalts. Among other uses, it can also be applied as a standalone lightweight waterproofing. Excellent deep penetration ability. It is capable of leveling micro-cracks in the substrate. Resistant to weak acids and alkalis. Suitable for both dry and damp substrates.

Type of substrate:
Concrete and similar mineral substrates, eternit, steel and metal elements (roofs, cladding, conduits and penetrations), cardboard and similar bitumen-based materials, wooden substrates and substrates based on wood (cement-bonded and gypsum-fiber boards, OSB boards, etc.).

Preparation of the substrate:
The substrate must be solid, free of any dirt (dust, rust), without sharp edges and standing water. It must not be frozen or covered with hoarfrost, it may be slightly damp. New plasters and concretes must be matured. Old brittle and peeling layers with weak adhesion must be removed. Cut blisters in the bitumen membrane in a cross shape and reinforce using Roof Bitumen Adhesive (Tixoplast) or DenBit BOND. Fill small unfilled areas in bitumen substrates with DenBit U repair filler. In case of damage to the load-bearing substrate, it is necessary to fill the sunk areas with special mortars, e.g., Filling Repair Filler for Concrete Den Braven, Final Repair Filler for Concrete Den Braven, and subsequently proceed to supplement the missing waterproofing.

Tools :
Brush, roller, tar brush, spraying device – only for the priming of dry substrates.

Working procedure:
Apply by rubbing the material into the substrate with a roofing brush or roller. In the case of a slightly damp substrate, it is necessary to rub vigorously, do not use a spraying device on a damp substrate. For lightweight waterproofing, apply all additional layers with a brush or roofing brush after the previous layer has dried properly.
