We have pumped, shot, spilled, splashed, sprayed, poured and injected polyurethane foam into every imaginable type of concrete structure known to man. 99.9% of it has ended up where it was supposed to go.

But there are those rare occasions when a small amount may end up ON the concrete we are trying to fix. Luckily that’s NOT a problem at all, because we use Spetec Surface Guard to prevent staining from polyurethane resins!

Spetec Surface Guard is a concentrated product that we mix with 3-5 parts water. It can be sprayed onto concrete, wood, metal, or plastic and creates a barrier layer that prevents polyurethane foam from sticking to and staining the surface.
