Brushable Waterproofer for Roofs

Bostik Brushable Waterproofer is a solvent-based, bituminous waterproofing compound formulated for general-purpose roof protection. Designed for use on all common roofing substrates, it incorporates a fibrous filler to improve crack-bridging capability and enhance durability. Once cured, it forms a tough, continuous black coating that provides long-lasting waterproofing performance.

Ideal as a heavy-duty brush-applied coating for roof waterproofing and resealing, it can be applied to a variety of surfaces including asphalt, roofing felt, concrete, corrugated iron, fibre cement boards, slates and tiles, lead, copper and zinc. Its solvent-based formulation makes it particularly suitable for applications where frost or rain conditions prevent the use of water-based alternatives.
