Foam sealant is a type of spray polyurethane foam product that is applied in a bead type application. There are a variety of uses for foam sealant. You can use this product to shore up doors, create protective molds and more. Typically, foam sealant is a tool for weatherization or insulating purposes. You can purchase a small can of sealant to get effectively the job done.
DIY
Do-It-Yourself projects such as creating extra storage, adding additions and so on typically call for some insulating foam sealants. For instance, this particular kind of sealant can be used to secure a window, living spaces, house exterior, basement or crawlspaces as well as secure open spaces in attics. Additionally, many homeowners have taken matters into their hands by using sealant as a form of pest control i.e. debugging a garage, sealing off hives or keeping other pest/animals out. The point is that foam sealant can be whatever you need it to be when it comes to getting creative with your DIY home projects.
Standard Uses
More standard uses for this particular kind of foam include your everyday insulation projects. The sealant can be used, as previously mentioned, in attics and any area of the house that needs better insulation. For example, the sealant can be used in basement and crawlspaces to make these areas warmer and dryer. The sealant is typically used in attics for the opposite effect as a sealant can keep the heat out your living space by applying it to attic hatch door frames, gas and cable lines as well as any other penetrations.
Hiring a Professional
Sealants purchased at your local hardware stores are small 12-24 oz cans. The cans are, therefore generally used for small projects such as filling smaller gaps or cracks around the house. What this means is that the large insulation jobs should be left to the professionals, as the mid-to-larger size insulation projects required another type of polyurethane foams.
Additionally, mid-size insulation projects tend to require more training. More training is necessary with these projects as there are low-pressure two-component kits and specialized equipment that must be used. A large-size project like the insulation of a roof uses high-pressure two-component SPF systems, which are not recommended for DIY use. Therefore, if you have a mid-to-large size project, it is imperative that you hire a professional.
