3. PRODUCT DESCRIPTION
RenuWall A300 is a high-performance, acrylic, elastomeric coating for above-grade exterior walls. It provides superior weatherproofing and long-term durability, with excellent adhesion, elongation and toughness.
RenuWallprovides outstanding resistance to weathering, temperature changes, ultraviolet radiation and mildew. It retains its bright color, long-term flexibility, and breathability for many years.
RenuWall moves with the expansion and contraction cycles of a building to keep hairline cracks well sealed. As shrinkage cracks occur in new stucco, RenuWallbridges these openings to maintain a water tight and attractive surface.
RenuWallexceeds stringent ASTM D6083 and AIA 9830 performance requirements for elastomeric waterproofing coatings.
