Product Description

The Dow GREAT STUFF™ Pestblock Insulating Foam Sealant is built as a pesticide-free way to block spiders, ants, bees, cockroaches, mice, and other insects and rodents while also insulating and air-sealing the location.


Build

This product will adhere to most building materials.

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.

Seals gaps and cracks up to 1” to provide an airtight seal and is water-resistant.

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.


Pestblock contains NO pesticides so it is a friendly way of blocking pests from entering any location!


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.

How to Use

  • Shake can vigorously for at least 30 seconds
  • Dispense slowly, this product expands!
  • Mist with water to speed curing times
  • Dries grey colored and cures rigid
  • Not suitable for being dispensed in cold temperatures
