High Performance Elastomeric Wall Coating Systems

renuwall-smalllWhether you have a newly constructed building or looking to restore your current buildings exterior walls, the RenuWall elastomeric wall coating systems provides superior weatherproofing, long-term durability, excellent adhesion, elongation and toughness.

These systems deliver high-performance, acrylic, elastomeric coating for above-grade exterior walls.  RenuWall provides 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.
