Developed by Sprayroq, SprayWall® is a durable, spray-applied, 100% VOC-free polyurethane coating that provides both structural enhancement and chemical resistance against all elements that eat away at underground structures. SprayWall® is fast and easy to install. Because of its unique formula, curing will begin in less than 30 seconds. Moments later, the structure can be returned to service.

Typically, an epoxy must cure for 6-24 hours. Sprayroq’s polyurethane products begin curing in approximately 10 seconds. Spraywall reaches a tack-free state within 2 minutes and full cure-through within 4-6 hours.
