How We Chose the Best Expanding Foams

Selections for the best expanding foam depended on the thickness after curing, water resistance or waterproofing abilities, quantity, and special features.
Tips on Using Expanding Foam
Expanding foam expands. That may seem like an obvious statement, but it’s something that can be all too easy to forget while spraying the foam into a deep cavity or recess. If the foam is sprayed too quickly, the crevice or gap can overflow, leaving a dripping mess that must be removed with a utility knife after it dries.
FAQs
Expanding foam products are designed to seal cracks and gaps, secure plumbing and wiring, and block rodents and other pests from entering the home. Take a look below to find the answers to some of the most commonly asked questions about how to use expanding foam and the dangers it can pose.
One squirt and expanding foam puffs up to seal cracks, stop drafts, and deter bugs and rodents. It can be a DIYer's best friend, but only when used prudently
Insulating expanding foam sealant makes quick work of reducing sound transfer, stabilizing a wobbly showerhead, or even securing fragile items for shipping. However, it’s not suitable for all DIY projects, and if misused, it can be more troublesome than helpful.
DO check the expiration date of the foam before you start spraying it
In the can, expanding foam is a liquid containing polyurethane components that react when they come into contact with air, causing the liquid to expand. The foam performs best when it’s fresh, and most retailers will remove cans of expired expanding foam from their shelves.
DO use expanding foam to silence noisy water pipes
Expanding foam isn’t just for stopping drafts and heat transfer—if you’ve purchased a can to seal some drafts and have a bit left over, it’s just the ticket for silencing noisy pipes and water hammer.
DO keep a solvent nearby when applying expanding foam
After expanding foam cures, any excess is removed by cutting, sawing, or sanding away, so it’s imperative to apply it carefully to keep from getting the super-sticky foam on other things. If expanding foam gets where it shouldn’t, clean it away using a solvent, such as WD-40 or acetone, while it’s still foamy.
DO use PPE when using expanding foam insulation
When expanding foam is cured, it’s considered nontoxic, but isocyanates—the gases released during the application process—can irritate nasal passages and trigger respiratory problems. Also, when the foam is wet, it can irritate skin, causing rashes and redness.
