How To Effectively Use A Spray Foam Systems Rig

If you’re tackling an insulation job on your own, here are a few tips to help you effectively use a spray foam systems rig.

What Is Spray Foam Insulation?

Spray foam has many fantastic properties that make it a good choice for home insulation. It can not only increase the resale value of your home, but it is also resistant to insects, water damage, and mold growth. It is capable of expanding to fit even the tiniest of cracks, which can help keep outside air from leaking through. Overall, it can be an investment that can benefit you for decades to come.

How To Use Your Spray Foam Systems Rig

  • Safety. Spray foam chemicals can be hazardous when inhaled or come in contact with; however, wearing the proper gear will allow you to handle it safely. Always where a protective eye gear, a full body protective suit, and gloves. You can even tape the seam where the gloves and suit meet to ensure nothing accidentally gets through. Additionally, always wear a respirator to prevent inhaling anything nasty.
  • Moisture. Be sure that the surface you’re spraying isn’t damp. Using a moisture meter will help you gauge if the space is dry enough to get started. The surface shouldn’t have a moisture content of over 20 percent. If you’re positive that the space hasn’t been exposed to water in the last couple weeks you should be good to go, but if there is any doubt, it’s best to check beforehand.
  • Planning. Before using your spray foam rig make a plan of action. Because the chemicals will harden quickly it’s important to know how you’re going to cover the space with as few breaks as possible. After 30 seconds the nozzle will become clogged due to hardening meaning you’ll have to keep installing new ones after each break. This can be time consuming, and draw out the task longer than need be. Remove anything that could hinder your progress before you get started, and plot out how to best cover spaces seamlessly.
  • Plastic Covers. If the space you’re covering contains windows, cover them with thick plastic before getting started. This ensures you can easily spray around them without worrying about getting anything on them.
  • Technique. When starting to use your spray foam equipment outline the wall cavity along the perimeter and allow it to expand. This helps prevent any gaps and holes from being left unfilled. Continue to add layers as needed until the perimeter is filled. After this you can move on to the center of the cavity.
  • Over spraying. When using a spray foam systems rig there is always the chance for over spray. If this happens use a curry comb to gently scrape away the excess until it is filed down to the correct level.
  • Fiberglass Insulation. It is possible to combine spray foam and fiberglass insulation if you want. After spaying the perimeter of the cavity fill the interior with the fiberglass and let set. This can help you cut back on costs while still reaping some of the benefits of spray foam.


Using a spray foam systems rig isn’t necessarily difficult, but it can take some practice to nail the proper techniques. Always ensure you’ve taken the proper safety precautions before starting, and don’t hesitate to do some practice sprays into a bag or box before starting on the walls. Before you know it you can have the securely insulated walls that you’re house deserves.
