how to remove Bondo wood filler?

Bondo is a popular wood filler that can be used to repair car dents and holes. It’s also an incredibly strong substance that doesn’t dissolve easily with water or other household chemicals.

In fact, if you try using a solvent like acetone or alcohol on Bondo, you’ll probably end up damaging your project even further rather than removing the Bondo itself!

But don’t give up hope just yet! There are ways to remove Bondo without damaging your surface or wasting money on expensive acetone products: all it takes is some persistence and knowledge of what will dissolve Bondo.

How do you remove Bondo from wood?

Once you have a good idea of how to remove Bondo, you’ll want to get started. If there’s no way around cutting out the Bondo and re-gluing the pieces together, use a razor blade to carefully slice away at it.

Make sure you have all your safety equipment on before starting! You’ll need eye protection, gloves, and possibly even earplugs if the gun is very loud.

Next, use a heat gun (or other similar tools) to soften up any areas where there’s still too much glue holding things together.

Again: make sure everything is covered up with protective gear! You don’t want hot plastic going into your eyes or ears!

What will dissolve Bondo?

Bondo is a two-part epoxy filler that is used to fill holes, cracks, and dents in wood surfaces. Bondo is a hard, plastic-like material that can be sanded and painted. Bondo isn’t water-soluble, but it can be softened with acetone (a common ingredient in nail polish remover).

What will dissolve wood filler?

If you want to remove Bondo wood filler, acetone is your best option. A chemical solvent that is found in nail polish remover, acetone will dissolve the wood filler and allow you to scrape it off.

The problem with using acetone is that it will also dissolve the paint on top of the wood filler.

Depending on how much time has passed since you applied your finish coat, this may not matter or be an issue at all.

If there are years between when you applied your paint and now, then removing all traces of it may not be worth giving up on an old color scheme just so that you can change it later down the line with a fresh coat of paint or stain.

Acetone should never be used indoors unless there is adequate ventilation (and even then). It can cause severe damage to your lungs if inhaled too much over time—even if you’re only working with small amounts here and there—so make sure that whatever space where this project takes place has proper air circulation before starting work!

What is the difference between Bondo and wood filler?

Bondo is a two-part epoxy putty. It’s made from a combination of plastic and hardener that must be mixed together before use.

Wood filler is also a two-part product, but instead of being an epoxy putty, it’s simply sawdust mixed with glue and hardener. Wood filler is used to fill holes and dents in woodwork pieces like cabinets or furniture.

Does acetone dissolve Bondo?

Acetone is a common solvent that can be used to remove Bondo from wood. Acetone dissolves most plastics and is often used as the primary ingredient in nail polish remover.

If you don’t have any nail polish remover on hand, acetone can be purchased at your local hardware store or pharmacy.

Be careful when using this substance; it’s flammable and can cause irritation if it comes into contact with your skin or eyes.

How do you soften hard Bondo?

  • Use steam. Heat a large pot of water and bring it to a boil. Remove the pot from heat and set it aside. Fill a stainless steel bowl with hot water, dip in a rag and wring out excess water. Place the damp rag over the Bondo area for several minutes until softened.
  • Use a heat gun or hair dryer to soften [Bondo]. Hold an electric air blower at an angle to soften bondo so you can scrape away excess material with an ice scraper or putty knife. Be careful not to get too close because excessive heat may damage surrounding paint surfaces or even plastic parts like headlights that are difficult if not impossible to repair (see tip #9).

Is Bondo water soluble?

It is possible to remove Bondo with water or a solvent. A solvent is a chemical that can dissolve the polymers in Bondo and other adhesives. You may be able to use a chemical solvent or water, but it depends on the type of Bondo you used and how much time has passed since you applied it.

If your project requires removing large amounts of Bondo, it’s best to use an industrial-strength solvent designed specifically for polyurethane-based fillers such as this one sold by Wynn’s Garage Supply Co.

Call ahead before ordering so they can help determine whether your product will work well for this purpose; some solvents are more effective than others at dissolving certain types of filler (this one works well on polyurethane).

This particular product dissolves Bondo wood filler within 30 minutes in most cases, though if there are multiple layers, those will take longer to dissolve completely—upwards of 1 hour per layer!

Will sandblasting remove Bondo?

If you are trying to remove Bondo from a wood surface, sandblasting is the best way to do it. A fine grit sandpaper works well for this task.

Make sure that you wear safety goggles and a respirator while sandblasting so that the dust doesn’t get in your eyes and lungs.

Using a drill with a sandpaper attachment can also be effective in removing Bondo; however, using a wire brush after to remove any remaining residue will ensure that there are no hairs stuck in the Bondo before it dries completely.


Although there are many different methods to remove Bondo, the most important thing is to find one that works for you and your project.

We hope this article has helped you understand some of the options available so that you can make informed decisions when it comes time to remove Bondo from wood or other surfaces.
