SprayWall from Sprayroq is a 100 percent VOC-free, self-priming polyurethane lining that reinstates structural integrity while providing infiltration control and chemical resistance for concrete, steel, masonry, fiberglass and other surfaces of structures, allowing manned entry. Environmental and climatic factors such as freeze/thaw cycling, high humidity, or shrinking/swelling soil conditions have minimal effect. Its gold color is derived from its raw components’ natural coloration. It provides coverage of 16 square feet per gallon at 100-mil thickness, and it is applied using a heated, plural-component spray system. Its quick curing time allows newly protected structures to be returned to service shortly after application is complete. 800-634-0504; www.sprayroq.com.
