Send gaps & cracks packing
Your attic, basement and just about anywhere in-between may have gaping joists, holes in wood, cracked blocks and more. Part of the PRO family of products, the GREAT STUFF PRO Gaps & Cracks Insulating Foam Sealant fills, air seals and insulates small gaps inside and out. Perfect for use with the Pro 14 Dispensing Gun, it sprays on easily and dries quickly. The result is greater comfort for the whole family.
Great stuff pro gaps & cracks benefits and suggested application
Can be used on gas line, pipe, and electrical wire penetrations. Orange in color so inspectors can easily recognize this approved fireblock foam. Resists water intrusion and maximizes energy efficiency.
Rim joist application
Seal the intersecting edges of the rim joist, foaming around 'boxes' of foam board or remove your existing fiberglass insulation, air seal and allow foam to cure, and place the fiberglass back in this space.
Sill plate application
Fill the gap where the pressure-treated wood meets the concrete foundation. This is a very common area of energy loss, so sealing this gap will improve comfort and increase customer satisfaction.

This foam cures with the moisture in the air. In dry weather, moist (not soak) the cavity you want to fill with a light spray of water before applying the foam. You will get twice as much expansion and no voids.
These cans go a long way; good bargain for the price, good value for the quantity. The applicator gun you need to buy to use these large cans seems a bit pricey (about $35) but is necessary and works well. None of it was very heavy to use. The applicator gun did not clog though sometimes I had such a gob of orange hardening foam on the end I couldn't see how it could possibly continue to work, but it did.
Downsides--the applicator gun doesn't extend very far so it was hard to reach into narrow spaces. The can itself sticks out awkwardly and has the same disadvantage. The can will spray upright or on its side, but not upside down, so it was hard to get into some areas by the ceiling between the joists.
The whole process is messy and sticky. Wear disposable clothing, if you can, gloves and goggles.
Added 5-11-2012: Just used a can that was partly used and left attached to the applicator gun for about 6 months, worked great. Not clogged at all and the foam worked perfectly.

Works perfectly -- bright orange but you need to buy separate gun tool to use.
