Spray Foam Preparation

So, you have chosen to kick out the pink stuff and insulate your home using polyurethane foam insulation instead. Congratulations! You're on your way to reaping the benefits of more energy savings, less mold, fewer air leaks, greener materials, and twice the protective capability when compared to traditional fiberglass and cellulose insulation. But you won't see these advantages if you do not apply spray foam insulation properly - and that begins before you start spraying.Before you even think about moving forward, you should be thinking about safety. Protective safety goggles, full-cover clothing, a mask, and work gloves are a must for anyone applying expanding foam insulation. Make absolutely sure that no skin is exposed during application, because the adhesiveness of spray foam is similar to that of permanent glue: it will stick to skin and will not come off. If this occurs, the insulation will remain on your skin until your outer epidermal layer peels off. For the record, the only substances known to remove expanding foam are white spirit-based solvents - and only then if the insulation has not begun to set. Applying polyurethane foam insulation also opens the possibility of the material getting into your lungs, which can cause respiratory problems. In short, get confident in your ability to apply spray foam properly.Once you are ready to proceed, make sure the area where the spray foam is to be applied is between 65 and 80 degrees Fahrenheit. If it is not, either wait for the temperatures to decrease or warm the area using a bullet heater. Also, make sure the application area is clear of debris and dust in order to maximize adhesion. If there are holes or cracks in the walls or ceiling areas where you are spraying, make sure that you apply a sealant to insure a suitable air seal.Once the area to be sprayed is ready, you must turn your attention to the areas that will not be sprayed. Windows, doors, floors, drywall, and other areas must be masked with cloth or plastic sheeting so they won't be affected by over spraying. If there are any objects or structures that cannot be removed before spraying (such as air conditioners, plumbing piping, or heating units), then make sure they are completely covered as well. Again, one gap in your protective sheeting could result in a spot or stain which you may be unable to remove.Now it's time to turn your attention to the spray foam insulation equipment. Like the application area, the insulation kit tanks should also stay within the 65 to 80 degree range before and during spraying. Also, make sure the pressure settings on the tanks are set to the manufacturer's specifications. Next, take the spray hose and check it to make sure there are no blockages of any kind. Fasten the hose to the insulation kit tank, using a wrench to properly tighten them together. When you are ready to begin spraying, open the valves by turning them counterclockwise.The spraying process itself is much like applying spray paint, coating the area with smooth, broad strokes. Most expanding foam insulation manufacturers recommend spreading the product with a thickness of one inch. After it dries, the spray foam will keep your home better insulated than fiberglass, and you will start seeing some energy cost savings. But those savings will not appear if you don't apply the expanding foam correctly. It's very important that you take the time to prepare for properly applying spray foam. Because, like most things, installing polyurethane foam insulation in your home is easy - if you know how to do it right!
