Did You Know?

1. Great Stuff, a popular brand of expanding foam sealant, is indeed waterproof. Once it cures, it forms a water-resistant barrier that can protect against leaks and prevent water damage to surfaces.
2. Great Stuff is commonly used to fill gaps and seal cracks, but did you know it can also be used for creative purposes? It has been used by artists to create unique sculptures and textured art installations.
3. Great Stuff is not limited to just waterproofing and artistic applications—it is also used in theater and film productions. It can be used to create props or simulate certain effects like faux rocks or foam-filled objects.
4. The Great Stuff label advises users to wear gloves and eye protection while handling the product. This is because it is made of powerful adhesives and expanding agents that can bond to skin and eyes if not careful.
5. While Great Stuff is highly effective in sealing gaps and holes, it is not intended for use as a standalone adhesive. It is important to use it in conjunction with other proper adhesives when necessary to ensure long-lasting and secure bonds.

Frequently Asked Questions

Is Great Stuff watertight?

Great Stuff is a highly effective product that offers valuable assistance in various projects. While it has impressive water resistance, it is important to note that it is not watertight. Despite its water-resistant properties, prolonged exposure to water or submersion will cause the product to become waterlogged and lose its structural integrity. Therefore, it is crucial to take this into consideration when using Great Stuff for any waterproofing needs.

Is expanding foam waterproof?

While expanding foam does offer some level of water resistance, it is important to note that it is not completely waterproof. While it can help reduce water damage to an extent, it should not be relied upon to resolve water leakages, especially in areas prone to such issues like basements. The foam’s primary function is insulation and filling gaps, rather than providing a watertight seal. Therefore, it is always recommended to address water leakages with appropriate and specialized waterproofing solutions in order to ensure long-lasting protection.

Does Great Stuff work under water?

Yes, Great Stuff does have some level of effectiveness underwater, thanks to its waterproof properties. However, it is important to note that its performance may be compromised in certain conditions. Over time, Great Stuff can start to deteriorate, especially when exposed to water for extended periods. Additionally, if it is applied on an unstable surface with a shifting substrate, there is a risk of cracking and splitting as the substrate moves. Therefore, while Great Stuff can provide waterproofing to a certain extent, its long-term durability and effectiveness underwater may be influenced by environmental factors and the stability of the application surface.

What spray foam won’t absorb water?

One spray foam that won’t absorb water is closed-cell polyurethane foam. This particular foam is known for its waterproof properties, making it an excellent choice for various applications. Its closed-cell structure prevents water absorption, making it suitable for lining boat hulls and providing protection against potential sinking. Additionally, closed-cell polyurethane foam offers good insulation, adding to its appeal and versatility.
