Product Description

The Dow GREAT STUFF™ Big Gap Insulating Foam Sealant is built to fill gaps from 1 inch to 3 inches wide and also provide 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!

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.


Fills gaps from 1 inch up to 3 inches wide!


Safety

Wear eye protection, gloves and protect the area from 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 in well ventilated areas.

How to Use

  • Shake can vigorously for at least 30 seconds
  • Screw straw assembly onto valve
  • Dispense slowly, this product expands!
  • Mist with water to speed up curing time
  • Dries cream colored and cures ridgid
  • Not suitable for being dispensed in cold temperatures


NOTE*** This type of dispensing can is for 1 TIME USE ONLY as foam will cure itself and make it impossible to dispense anymore product!
