If you want to save money on insulating your home, then spray foam insulation kits are a great idea. You can save thousands of dollars by doing the insulation work yourself with a $400 spray foam insulation kit covering about 25-feet of an 8-Ft wall (or 200 sq Ft.), a reasonably easy process for the avid DIYer. Applying spray foam insulation is not much different from working with spray paint. With the help of this handy guide, you will learn how to use a spray foam insulation kit and insulate your home in no time at all. Let's get started.

1. Prepare Your Materials

Before you start spraying the foam insulation in your home, you'll want to make sure you pick up all of the materials you will need at your local hardware or home improvement store. When doing your shopping, make sure that to purchase a spray foam insulation kit that comes with adequate instruction materials as well as all of the tools and accessories that you will need to do the job.

You will also have to get yourself some personal protection gear ready before starting. Work gloves or disposable gloves, a hat, as well as safety glasses or other protective eyewear, are a definite must, along with wearing old clothes that you don't mind discarding afterward.

2. Check the Temperature of the Materials

Before you get started, you should check the temperature of the insulation kit tanks to make sure that they are in the proper temperature range. Generally speaking, the tanks should be between 65 and 85 degrees Fahrenheit. If the temperature is too cool, you may be able to use a forced fan heater or another heat source to warm the tanks. However, if the tanks are too warm, you'll simply need to wait until the weather cools down.

3. Prepare the Area to be Insulated

Clean the area where you'll be installing the foam insulation thoroughly before you start spraying. Remove any dust and debris with a broom or a vacuum cleaner. Also, wipe down the surface of the walls and studs with a damp cloth to remove cobwebs and dust that may prevent the foam insulation from adhering to the surface.

4. Get Your Equipment Ready

To prepare the equipment for use, you'll usually only need to connect the spray hose to the tank that is supplied with the foam insulation kit. Then you'll need to open the valves on the tanks by turning them counterclockwise so that the insulation foam can flow through the spray nozzle.

5. Spray the Foam Insulation

Before starting the spraying process, make sure to wear your protective eyewear, gloves, and hat, as the foam will bond with extreme persistence to anything it comes in contact with. Be aware that once the expanding foam cures or dries, the only way to get it off your skin is by sanding or scraping it off. Acetone is the best if not the only solvent for dissolving uncured polyurethane foam.

With this taken care of, in order to spray the foam insulation, grab the nozzle by its handle always aiming it at the wall, hold the spray nozzle about 12 to 16 inches away from the wall where you will be applying the foam. Then, spray the foam with a back-and-forth motion similar to that which is used when applying spray paint. Also, make sure not to apply too much insulation in any one spot. Generally speaking, you only need to apply a very thin layer of foam insulation for it to be effective.

6. Allow the Foam Insulation to Dry

After you spray the foam insulation, you should give it enough time to rise and dry completely. In most cases, the insulation should dry in about 20 to 30 minutes. For all practical purposes, once the foam insulation is dry, you are done.

7. Inspect the Wall for Missed Spray Spots

Before you put the spray hose and nozzle away, inspect the surface area of the wall where you sprayed the insulation. Check for any spots that you may have missed and fill them as needed.
