New & Improved EXPANDO permanently seals holes and cracks while spot insulating wherever it is used. It expands up to three times its original volume to seal out air, drafts, dust, moisture and pests. When cured, EXPANDO is waterproof and weather resistant. Bonds to wood, masonry, glass and most plastics. It is tack free in about 15 minutes and cures fully in 8 hours, depending on temperature.

Directions for Use
EXPANDO is FLAMMABLE during dispensing. Shut off all gas pilot lights, electrical igniters and other sources of ignition before and during use.
Shake can vigorously for at least one minute before use. Screw trigger/straw assembly on to valve. Holding can UPSIDE DOWN, slowly pull trigger until foam flows smoothly. Fill crack or hole 1/3 full, allowing room for expansion as it dries and avoiding wasting any of the product.
NEVER activate valve with can right side up – propellant will escape. Clean uncured foam immediately with paint thinner, acetone or nail polish remover.
