3 Tips For Injecting Your Garage Walls With Spray Foam Insulation

Posted on

If you have decided to turn your garage into a workshop, you may decide to inject spray foam insulation into the walls so you can work when it is warm outside. If so, use the following tips to help make the installation go more smoothly:

Shake the Canister Frequently

Before you start injecting the insulation and during the installation process, make sure you shake the canister frequently. Doing so will ensure that the insulation goes into the wall evenly so it can fill every nook and cranny.

Depending on the type of spray foam insulation you use, there will be two or more ingredients that combine to create it. Also, the propellant within the canister needs to be mixed thoroughly to ensure the foam does not go in too thick or too thin. Shaking the canister between applications keeps this from happening.

Start with Light Pressure on the Trigger

Especially when you first start injecting your walls with the foam, use light pressure on the nozzle's trigger. Because the propellant can be powerful, you do not want to force too much foam into the walls at one time. 

Until you get a feel for how much foam will be dispersed, push down gently until it starts spraying out. Then, apply more pressure to see how far the foam travels. This will give you an idea of how much pressure you will need to reach the furthest corners of your walls' interiors.

As you fill the walls with the insulation, you also want to judge how much pressure you need during the injections. If you are trying to reach a far corner, you may need to apply more pressure. However, as the foam fills in the spaces close to the injection hole, lighten up on the trigger so you do not overflow it.

Have Backup Nozzles Ready

Another thing that will make your job of injecting spray foam insulation easier is to have backup nozzles handy. Because the spray foam thickens and hardens over time, your first nozzle may become clogged up before you finish the job.

If you find that you are having to apply heavy pressure on the trigger and very little foam is coming out, the culprit is most likely a blocked nozzle. Change the nozzle when this happens.

Using the above tips can help make your job of injecting your garage walls with insulation easier. However, if you run into a problem or decide you do not want to do the task yourself, contact a contractor who installs spray foam insulation to discuss your options for having them do the job for you.
