Questions and Answers for GREAT STUFF 16 oz. Pestblock Insulating Foam Sealant

A:  Hi, JT! Thanks for your interest in Great Stuff™ Pestblock Insulating Foam Sealant. This product is designed to fill gaps and cracks up to 1" to block areas where pests commonly enter your home. On each can, there is a "best if used by" date on the bottom, underside of the can.

In order to achieve the best results, we recommend that you apply a layer of foam and let it cure before adding layer of steel wool or wire mesh and applying a second layer of foam. This makes the foam more difficult for a mouse to chew through.
