About DAP 4001020012 20OZ MX EXPND FM SEALANT
Triple expanding sealant is an interior/exterior insulating product that stops household air infiltration by expanding to fill cracks where standard insulation is ineffective. Made with renewable resources it creates an airtight weather-resistant bond that seals out drafts and blocks insect and pest intrusion. Expands approximately 3 times its original volume. Foam can be dispensed at any angle; however, upside-down dispensing is the most efficient means of delivery. Fill gap no more than 1/3 full allowing room for expansion. Foam is tack-free in 30 minutes. Excess foam can be trimmed, sanded, caulked, or plastered in 1 hour. Dispense by connecting straw to adapter. Can may be restarted for up to 3 weeks. UL classified.
