High performance, tough, flexible, polyurethane waterproofing membrane, for internal and external areas.

Nitoproof 750 is a single-component polyurethane liquid which cures by reaction with atmospheric moisture to give a tough elastomeric waterproof membrane. It is supplied as a thixotropic liquid which is easily applied at the recommended thickness to both vertical and horizontal surfaces.

The high elasticity, excellent bond and low water permeability of Nitoproof 750 make it ideal for a wide range of water/vapour proofing applications such as foundations, basements, tunnels, ground floors, suspended floors, roof terraces, balconies, patios, bridges, inspection pits, sewage works and inverted roofs.
