DAP Wall & Cavity Foam with Widespray Applicator kits are portable, self-contained one-component polyurethane foam dispensing kits. When used according to manufacturers directions, they effectively air seal and insulate homes and buildings while enhancing R-Value and providing Class A fire resistance. The patent-pending technology offers a broadcast spray solution similar to two-component systems, but in a less complicated, easier to use one-component solution. This one-component system can be applied in a wide temperature range of 40 F - 120 F. Great for repairs, renovations and new installations. Not to be used for direct overhead spraying applications.
