This is just the basics. In the post, we go over the details in more depth.

How to Remove 2 Types of Expanding Foam

There are some do’s and don’ts to using expanding foam that everyone should know about. Accidents can mainly happen when you aren’t aware of them. 

And when you get that expanding foam, you risk getting hurt. You can find expanding foam in 2 forms.

One is Cured Expansion Foam and the other one is Uncured Expanding Foam. 

We’ll go over the steps of removing both of them. Let’s not waste any more time and go into them right away-

Removing Uncured Expanding Foam in 3 Steps

Uncured Expanding Foam refers to the type of foam that is still wet. If the foam on you is still wet, then the risks are lower. 

Once it heals, it becomes really difficult to take it off. 

Let’s go into the steps now!

Step 1: Wipe It Off

It’s quite clear if the expanding foam has been mended or not. If the foam is still wet, then it hasn’t healed. But if it has dried, it means it has cured. 

The expanding foam being wet means you can just wipe it off very easily. You may clean it up with a piece of cloth or tissue. 

The process would be faster if you’re by any chance using expanding foam under the bathtub. You’ll be closer to tissues after all. 

We’d suggest you not use any cloth to wipe it off. Because it’d be in your best interest to throw out that cloth. So it’s best if you use a paper towel or a paper napkin. 

Step 2: Use Acetone

Acetone is a chemical component found in everyday goods such as nail polish removers. It’s unlikely to be found in any other kitchen or household item. 

If you can manage pure Acetone then that would’ve been best. But you can get the job done with a nail polish remover. 

Check if your nail polish remover has Acetone in it though. Not every nail polish remover has them. 

So, here’s a list of nail polish removers that has Acetone:

Pour some Acetone or nail polish remover on a tissue first. Then wipe the parts where the Expanding Foam was. 

Be very careful with the Acetone though. It’s a very volatile and highly flammable substance. You can easily catch yourself on fire. 

Step 3: Wash Your Hands

It is not necessary for you to maintain the Acetone on your person. Actually, don’t keep the Acetone on yourself at all. It might cause a burning sensation or irritation afterward. 

As soon as you’ve finished rubbing it on your hands, use water to wash it off. You’ll be able to remove the remaining bits of expanding foam as well. 

After that, wipe your hands with a clean, soft towel. Acetone actually removes all the oil from your skin. 

You should use lotion or lanolin on your hands to make up for the lost oil. 

Removing Cured Expanding Foam in 3 Steps

You know by now what cured expanding foam is. It’s basically dried expanding foam. It’s called cured once it dries up. You can’t use water or chemicals to remove it. 

Basically, it won’t matter if you were using expanding foam under your shower pan. You might be in your washroom ready to wash it off. But if you don’t notice it, it’ll dry up. 

Now we’ll look at how to get rid of cured expanding foam-

Step 1: Rubbing With Pumice Stone

To take off cured Expanding Foam, you need Pumice Stone. Using any chemical like Acetone won’t do you any good. 

You won’t be able to scrub it very easily with just about anything. A Pumice Stone would work best for this job. 

Gently rub it on your hands until all of the dried expanding foam falls off. 

You’ll have to rub for a while to remove all of the expanding foam. Wash both hands using soap and water after removing them. 

Step 2: Application of Moisturizer

Your skin will have become rough and dry by now. To fix that, you’ll be applying moisturizer in a different way. 

You can use lotion, petroleum jelly, lotion, or lanolin. Apply them evenly on your hands and then cover your hands. You can use thin plastic paper or you can use gloves. 

Gloves would be better if you ask me. Stay like this for almost 2 hours.

Step 3: Wash Your Hands

After two hours you can take off the gloves. Hands should be washed thoroughly with soap and water. The moisture in your hands should be back by now. 

If your hands are still dry, repeat the moisturizer application technique. 

Follow these two processes and you’ll have nothing to worry about. If you thought these steps looked familiar then that’s because it could be true.

Question: Can I remove expanding foam?

Answer: Yes you can remove expanding foam once applied. You should use a utility knife to scrape them off from the walls. 

Question: What does expanding foam do?

Answer: The main purpose of expanding foam is to fill up holes and cracks inside your house. It shoots the foam in such a way that the holes get covered up. 

Question: Can I use baking soda to remove expanding foam?

Answer: Yes, baking soda may be used to remove expanding foam. But you should mix it with some vegetable oil first. After that, you should apply it to your skin.


Now you know how to remove expanding foam from your hands.

Follow our process of getting it off thoroughly and you’ll be perfectly fine. 

If you still feel a burning sensation or irritation, go see a doctor. 

Good Luck!
