- Installs similar to foam insulation, but comes in an aerosol can and is best for do-it-yourself use.
- Best used for permanently sealing irregular gaps around the home, such as plumbing feed-thrus, electrical outlets, vents, etc.
- After curing, it can be trimmed, sanded and painted.
- When installing, only fill the area about 33 percent and the expanding foam will fill and seal the rest of the area.
- Formulations include triple-expanding for general-purpose sealing and insulating; minimal-expanding for windows and door frames; and fast drying for multi-step projects such as filling a crack before painting.
- Wear gloves and eye protection when applying.
- Remove wet foam with acetone or acetone-based nail polish remover. Cured foam is difficult to remove from skin and clothes.
