Is Great Stuff Foam Waterproof?

Is Great Stuff Foam Waterproof? is a question many people ask. The answer is yes and no.

Great Stuff Foam is waterproof when it is first applied, but after it dries it is only water resistant.

Most people think that Great Stuff foam is waterproof because it is used to seal cracks and gaps in homes. However, Great Stuff foam is not waterproof and will absorb water if it comes into contact with it. This can cause the foam to swell and break down over time.

If you need a waterproof sealant, you should use a different product such as silicone caulk.

Is Expanding Foam Waterproof?

No, expanding foam is not waterproof. When used outdoors, it will eventually break down and degrade due to exposure to the elements. However, there are some products on the market that are advertised as being “waterproof” expanding foam.

These products typically contain a waterproofing agent (such as silicone) that helps to protect the foam from moisture.

Which Spray Foam is Waterproof?

There are two main types of spray foam insulation: closed-cell and open-cell. Both types are effective at insulating against heat, cold, and moisture. But only closed-cell spray foam is waterproof.

Closed-cell spray foam is made up of cells that are completely sealed off from each other. This makes it an effective barrier against water and moisture. It also gives the material a higher R-value, or resistance to heat flow.

That means it’s not only waterproof, but also one of the most effective insulators on the market. Open-cell spray foam has a more spongy texture than closed- cell foam. Its cells are not as tightly sealed, which allows water and moisture to enter them more easily.

As a result, open-cell spray foam is not waterproof. However, it’s still an excellent insulator and can help reduce energy costs in your home or business by keeping out drafts and controlling temperature fluctuations.

What Happens to Spray Foam When It Gets Wet?

When spray foam gets wet, it can start to break down and degrade. This is because the water can start to break down the bonds between the cells in the foam. This can lead to the foaming shrinking and becoming less effective as an insulator.

In some cases, wet spray foam can also start to mildew and rot.


Waterproofing your home is important to prevent damage from water leaks and flooding. Great Stuff foam is a popular product for waterproofing because it is easy to use and effective. However, some people wonder if Great Stuff foam is actually waterproof.

The answer is yes, Great Stuff foam is waterproof. The foam expands to fill gaps and cracks, creating a seal that prevents water from getting through. You can use Great Stuff foam on both the inside and outside of your home to create a waterproof barrier.
