WMA Barrier Pro PU is a single-component, liquid-applied polyurethane waterproofing membrane that moisture-cures to form a seamless elastomeric barrier. Its anti-sag formulation supports controlled film build on vertical surfaces and the membrane can be applied by brush, roller or squeegee. Once cured, it provides high elasticity, crack-bridging capability, adhesion and resistance to water penetration. Barrier Pro PU is designed for protected internal and external waterproofing applications beneath tiles, screeds or other suitable coverings. Supplied in a 19kg pail, it is typically ready for covering within 24 hours under suitable conditions.
  • Single-component application removes the need to mix separate components.
  • Moisture-curing polyurethane forms a seamless elastomeric waterproof barrier.
