Lapolla Industries Inc., the global supplier and manufacturer of high performance, energy-efficient building products, announced the launch of WALL-LOK exterior elastomeric wall coating for waterproofing. A preventative exterior maintenance product for commercial structures, WALL-LOK is a coating solution that acts as both an effective waterproofing and UV protective barrier.  

“WALL-LOK is a solution aimed at protecting the structural integrity of the building by preventing moisture from getting into the interior of the walls,” said Doug Kramer, President and CEO of Lapolla Industries. “This coating provides exceptional value to commercial facility owners and managers looking to protect their properties from the moisture intrusion, enhance curb appeal and extend the longevity of the exterior structure.” 

Optimal for use across brick, concrete, masonry and exterior insulation finishing systems, WALL-LOK forms a durable, tough waterproofing film on the surface of the building. The barrier created by the acrylic-based coating and sealer is ten times thicker than standard paint. WALL-LOK prevents water penetration, one of the most significant enemies to a building. The coating blocks the formation of harmful mold, algae and mildew by eliminating moisture migration into the vertical and horizontal grout line of walls, protecting valuable inventories from damage. Additionally, it prevents mortar from crumbling due to water penetration, as well as inhibits salt stains and the rusting of steel and iron.

The high-performance product also contains reflective material that shields the structure from harmful ultraviolet rays, which are a common cause of both exterior color fading and degradation and the transfer of heat into the building. The product effectively maintains the outer appearance of the building exterior while reducing interior cooling needs and costs. 

WALL-LOK is optimal for use on commercial structures including existing apartment communities, industrial warehouse facilities, retail properties and office buildings. The high-fill thick coating and sealer is both flexible and stretchable. These characteristics make it ideal for bridging non-structural cracks and defective joints from hairline cracks up to 1/16 of an inch wide. 

WALL-LOK is available in a variety of colors including shades of white, tan and gray. Custom colors are also available.

“WALL-LOK is an excellent addition to our existing product line,” added Kramer. “The product aligns with our goal of providing best-in-class materials to achieve the highest performance in buildings.”
