Marldon Bitumen Paper is the ideal solution where damp is present in a timber subfloor. It creates a water-resistant barrier between the subfloor and the flooring to prevent any moisture being absorbed into the floor.
Crafted from wet-strength kraft paper and designed to meet the technical standards of BS 152, Class A1F, for waterproof building materials, this product incorporates a polymer-reinforced scrim. It serves as an excellent choice for situations demanding added strength and durability.
