Since spray foam insulation is a highly effective insulating material that can help keep your home warm and comfortable, many people decide to install it in their homes. However, it might be more challenging to remove the spray foam insulation from your house than it was to put it in.
You can remove spray foam insulation in a few different ways, such as by vacuuming it out, soaking the area in a solvent or chemical solution that breaks down the material, or scraping it off with a spatula or other tool. The approach that is most effective for you will be determined by a number of variables, including the size of the treatment area, the type of spray foam insulation used, and the amount of time the material has been in place.
It’s crucial to realize that this process can be labor- and time-intensive if you’re thinking about removing your current spray foam insulation because it’s become damaged or isn’t performing as intended. However, doing so over time can increase your home’s cost- and energy-effectiveness.
This article will cover a variety of topics, including whether spray foam can be removed, whether doing so is challenging, how to go about doing it, how much it will cost to remove spray foam that has already been put in, and more.
Here’s a quick rundown of how to remove spray foam insulation: First, cut off any larger pieces of foam with a putty knife. Then, use sandpaper to remove any remaining foam. Acetone can also be used to remove the uncured foam.

In their unexpanded states, most spray foam products resemble thick paint or heavy glue, and they adhere to anything. Because spray foam adheres to itself and stays put while expanding to create an insulating barrier, it is simple to apply to both large and small areas. However, it’s all too simple to misdirect the spray and get the foam on the furniture, woodwork, or worse, your hands and clothing. The task of removing the spray from a solid surface is frustrating but manageable, but it is nearly impossible to remove it from your clothing.
Step 5: Apply Lacquer Thinner
Applying lacquer thinner after the majority of the spray foam has been removed may be a good idea.
Uncured polyurethane-based products can be dissolved using the special solvent lacquer thinner. Once all the larger particles have been removed, experts like to use it to complete the removal of insulating foam.
Nail polish remover can be used in its place if you don’t have any lacquer thinner on hand. It contains acetone, which will also dissolve uncured polyurethane foams.
Please be aware, though, that cured foams cannot be removed with nail polish remover or lacquer thinner.
Remove Foam Sealant from Fabrics and Other Hard Surfaces
With a dry cloth dipped in acetone nail polish remover, remove wet foam sealant from the material or other surfaces.
Use a putty knife to remove dried foam sealant from the surface or fine-grit sandpaper to remove the foam.
On the dried foam sealant, use a foam sealant remover directly. Give the foam sealant remover five minutes to sit on the foam.
Rub the foam with a plastic scrubber or old toothbrush.
Wipe the remover from the item with paper towels. Continue until the dried foam sealant has been eliminated from the surface.
