Lapolla Industries, a global supplier and manufacturer of building products, recently released its 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 a waterproofing and ultraviolet (UV) protective barrier, according to the company.

“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,” he added.

How the Coating Works

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 10 times thicker than standard paint, Lapolla said.

WALL-LOK also prevents water penetration, a primary threat 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, thereby protecting valuable inventories from damage.

It also prevents mortar from crumbling due to water penetration and inhibits salt stains and the rusting of steel and iron, Lapolla officials said.

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

Optimal for Commercial Structures

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 .06-in (1.6-mm) wide.

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

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