GREAT STUFF Gaps & Cracks 20 oz Insulating Foam Sealant

Product Information

Fireproofing the home is very important, and some expanding foam products, designed to be highly fire-resistant, can be used for this purpose. The foam can seal holes between floors where wires and pipes run and can be used to seal gaps around wall outlet boxes to prevent loosening, while at the same time serving as a fire barrier should disaster strike. Keep dry: While moisture and humidity will help the expanding foam dry faster, it is not your friend for drying paint. Moisture will dry the paint at a much slower rate or result in uneven texture. To avoid this, keep windows and doors open or use a dehumidifier near the area. Sealants can help with crafts like prop making, castings, or filling in little gaps. For these projects, we recommend the Smooth-On Foam-iT! polyurethane foam. This foam sealant has a 5-pound-per-foot density and expands to 10 times its original size.

Always inspect the area where the insulation will be applied before installation. Older homes and homes with wooden shingles may be built with a design that allows the natural evaporation of excess moisture. Insulation installed in these areas acts as a sponge, soaking up the moisture instead of allowing it to dissipate. As moisture builds up, mold can grow and eventually rot out the wood. Great Stuff™ and Great Stuff Pro™ products can be used outdoors. However, cured foam will discolor if exposed to ultraviolet (UV) light. If left exposed, the foam will eventually crumble.

Insulate the House

As a general rule of thumb, you will want to keep expanding foam away from power sources and any flammable areas. This will help to prevent fire and other chemical reactions. The paints themselves are not flammable as they are water-based, and latex is not a highly flammable substance. The Smart Dispenser™ from the Great Stuff™ brand is a game-changing, industry best dispenser for one component can sealants. Temperature: For exterior applications, you will want to make sure that the outdoor temperature is suitable for proper drying. It is recommended to apply paint in temperatures above 50 F as paint does not dry well in cold environments. Paints usually dry well between 50 – 90 degrees F.
