Weatherproofing System

The RenuWall® Weatherproofing System from National Coatings is an excellent and cost-effective way to weatherproof and prolong the life of your exterior walls. This system provides resistance to weathering, temperature changes, ultraviolet radiation, and mildew. It retains its bright color, long-term flexibility, and breathability for many years, resulting in excellent adhesion, elongation, and toughness. This watertight weatherproofing system can be installed right over your existing walls. The RenuWall Weatherproofing System requires minimal maintenance and offers worry-free weatherproofing.

















RenuWall provides a tough film that moves with the expansion and contraction cycles of a building to keep hairline cracks well sealed. As cracks occur in a wall, RenuWall bridges these openings to maintain a water tight and attractive surface. The RenuWall weatherproofing system prevents water from entering the building through cracks as small as 1/16”, keeping the interior of the building dry and waterproof.

RenuWall coatings have high vapor permeability allowing moisture vapor to flow out of the wall and prevents liquid rainwater from infiltrating into the wall assembly. Superior dirt pick-up resistance allows RenuWall to continually look fresh and new throughout its lifespan. Also, RenuWall is environmentally safe and easy to use and exceeds stringent ASTM D6083 and AIA 9830 performance requirements for elastomeric waterproofing coatings.
