Foam sealant fills cracks and holes in homes and other structures.

Foam sealant is used to seal and fill holes and cracks throughout your home, garage or other structure. It is waterproof, airtight and can be painted or stained if needed. Foam sealant is a good choice for sealing cracks to keep rodents out of your home. The wet foam sealant expands and hardens quickly on most surfaces, including carpet, clothing and wood. Cured foam sealant is durable, so removing it can be difficult--but not impossible.
