DAP Gaps & Cracks High Density Foam with HydroAction Polyurethane is an expanding spray foam sealant that combines the high strength and durability of polyurethane with the ease of water cleanup. It delivers a strong, durable seal while allowing uncured foam to wipe clean with water within five minutes of application.

With most polyurethane foams, overspray and accidental contact normally leave behind sticky residue that requires chemical solvents or extra prep work to manage. DAP Gaps & Cracks eliminates that challenge because it can be cleaned up with water within five minutes of applications, making it useful in finished interiors and other areas where quick and clean results matter. The sealant seals and insulates gaps up to 1 inch wide, helping block drafts and moisture while supporting energy efficiency. It can be applied in temperatures from 25 to 105 degrees F. Use it to seal around pipes, plumbing fixtures, exhaust vents, and more.
