Introduction
Over the years, there has been a lot of talk about any expanding foam, but I have yet to find one that beats these top three. The top three most popular waterproof expanding foams are Foam Sealant, Gaps and Cracks Insulating Foam Sealant, and Great Stuff Pro.
Foam Sealant
Foam Sealant
Foam sealant is a popular option among homeowners. This expanding foam is used to create an airtight barrier around leaky areas in your home, such as windows, doors and other places where moisture can get inside the walls. The foam expands once it comes in contact with water or moisture and forms a durable layer that prevents water from entering the wall structure of your house. It’s also easy to use! Simply cut off an amount about the size of your hand and apply it to the area needing repair with your finger or a putty knife (no need for gloves). Then simply wait until it dries before replacing any panels on which you applied the sealant. For more details on how best to use this product effectively read our guide here: [link].
Now that we’ve covered what exactly foam sealant does let’s discuss some additional details regarding its benefits over other types of sealing materials such as tape or caulk so you know what makes them especially well suited for certain situations:
- Foam seals better than caulking because it creates an airtight barrier between two surfaces instead of just one side like caulk does (which means no more leaks!). This makes it ideal for preventing mold growth inside walls too since mold needs both moisture AND oxygen so removing either will make things harder on those tiny spores trying their hardest not die off due to lack of vitamins A & B12 (yes I did just say vitamins).
