DIY Frequently Asked Questions / Foam Sealant')">
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.
