Product details

Product description

A ready-to-use tanking coating formulated with Portland cement, graded aggregates and acrylic polymer modifiers. Applied by brush directly to damp surfaces, it cures to form a vapour-permeable yet watertight barrier that resists water pressure and prevents ingress in below-ground structures. Two coats are required for full protection.

Applications

Cellar and basement waterproofing
Below-ground masonry protection
Concrete and brickwork tanking
Prevention of water ingress in damp structures
