The Dow GREAT STUFF™ Gaps and Cracks Insulating Foam Sealant is built to fill gaps up to 1” wide and also provides air-sealing and insulation that can help you save up to 30% on home energy costs.

Build

This product is very sticky and will adhere to metal, masonry, wood, glass, and most plastics.

Dispense in any direction by using the provided straw that will help to direct the foam into the gaps and cracks you want to fill.

This foam expands and takes shape of the gap to create a water-resistant, weathertight airtight seal around electrical wires, plumbing pipes, ductwork, and more!

The product is trimmable after 60 minutes with a serrated blade and can also be sanded, stained, or painted. The surface of this foam can discolor when exposed to sunlight so it is recommended to paint it if this makes a difference to the appearance of the final finished project.

This is a MINIMAL expansion foam that takes on the shape of the gaps or cracks being filled!

Safety

Wear eye protection, gloves and protect the area from the excess product.

Uncured foam can be cleaned with acetone or GREAT STUFF PRO Cleaner for best results! Cured foam on hands or surfaces must be removed mechanically or allowed to wear off.

Keep ignition sources away from this foam and use them in well-ventilated areas.
