No one masters spray foam application right away when they’re just starting out as a contractor. However, with the right training and practice, you’ll have the proper techniques down in no time. For now, familiarize yourself with the common spray foam insulation mistakes to avoid as a beginner contractor.
Applying the Foam Too Quickly
Applying spray foam too quickly can lead to sparse areas of foam, meaning you may not thoroughly cover the entire surface area. When applying spray foam, your goal should be to achieve a nice, even coating. Make sure to check your spray foam rig for a clogged nozzle or hose, which would impede the pattern of your spray. This could also lead to an uneven spray foam application. Take your time and be patient to make sure you adequately cover the entire surface you’re working with.
Over-Spraying the Foam
On the other hand, it’s also possible to over-spray the spray foam insulation. Being too thorough with the application can lead to packing down the spray foam material. Some of the most common types of spray foam, including open-cell foams and closed-cell foams, expand slightly after application. You’ll want to give these foams a moment to expand to their full size before spraying another layer.
Spraying Very Hot or Cold Foam
Most spray foam kits and rigs have temperature adjustment options. You want to avoid spraying on your spray foam at too hot or too cold a temperature. If you apply the insulation when it’s too hot, the foam could become flaky and dry. When you spray foam that’s too cold, it may have a texture that’s too soft and spongy. You want the foam to be warm, but not hot, during application. This will ensure the right consistency of your spray foam insulation during application.
