how to remove wood filler from wood?

Wood filler is a great way to fill in cracks or holes in wood. It’s quick and easy to use, but it can be difficult to remove if you don’t know how.

You don’t want to be stuck with wood filler that’s too hard for you to remove, so this article will teach you the best ways of getting rid of hardened wood filler from your project!

How do you remove dried wood filler from wood?

If you have a small spot to fill, it’s best to use the filling compound for that purpose. Small holes and cracks can be filled with wood putty or spackling paste.

If you need to remove dried wood filler from wood, you’re likely going to have a larger area than what you can easily sand down by hand.

In this case, it’s worth investing in some power tools such as a paint scraper or chisel (and maybe even an electric sander) so that you don’t do more damage than necessary while getting rid of the old filler.

If your project involves removing old glue on top of the existing finish then consider using a vacuum cleaner before attempting any type of scraping or sanding; this will help prevent further damage caused by removing loose particles which could otherwise end up stuck underneath your sandpaper or scraping tool (or worse yet!—in your lungs).

Can you soften hardened wood filler?

Now that you know how to remove wood filler from wood, let’s talk about what to do if your filler is still there.

  • Heat it up. If you’re dealing with a dried-out and hardened piece of wood filler, you may need to soften it before scraping or sanding it away. This can be done with heat—either by using a heat gun or applying hot water and waiting for the moisture in the filler to expand and loosen its grip on the surface of the furniture. Be sure not to scorch anything! Some people find success by placing their piece of furniture near an oven while they preheat their oven (and then closing its door), but I recommend against this since it risks damaging your home appliance as well as releasing dangerous gases into your kitchen/household environment.
  • Try another method altogether: If all else fails, consider using some other type of tool instead! Scrapers are typically best for removing softened wood fillers because they tend not to cause damage even when used incorrectly; however, sanding sponges make great tools too because they conform well around corners without leaving behind any residue after use (unlike scrapers).

Can you sand off wood filler?

Yes, you can sand off wood filler. However, this process requires a good deal of patience and steady hands.

The best way to achieve smooth results is by using 120-grit sandpaper and working in small sections at a time—don’t try to remove too much filler at once!

If you’re not confident about your ability to sand the filler away without damaging the underlying wood, it might be wise to skip this step and opt for one of the other removal methods we’ve discussed above instead.

Is wood filler permanent?

You may be wondering if wood filler is permanent. The answer is yes, and no. While it can be removed with acetone (nail polish remover), water, oil, and heat, sanding off the excess filler will do the job just as well in most cases.

Does acetone remove wood filler?

Acetone is a solvent, which means it can remove certain materials. It will dissolve paint, varnish, and wood putty (resins).


  • Acetone can damage the wood underneath if you’re not careful with how much is applied.
  • Acetone can be toxic. Don’t breathe in any fumes when using this product!
  • Acetone is flammable—so make sure there are no sparks or open flames around when you use it!

How do you cover up wood filler after staining?

When you’re trying to cover up wood filler, you have a few choices. You can use one or a combination of any of the following:

  • Stain-blocking primer
  • Stain-blocking paint
  • Stain-blocking stain
  • Stain-blocking stain and primer

Are wood putty and wood filler the same?

Are wood putty and wood filler the same? The answer is no.

Wood putty is made from glue and sawdust, while wood filler is made from glue, sawdust, and water. Putty is a cheaper alternative to wood filler because it can be used as a temporary repair that requires less sanding later on.

Wood filler also has more uses than just filling holes; it can be used to level out dings in your furniture, or even add color so that you can match your existing furniture pieces without having to refinish them!

Wood fillers are stronger than putties but both come in handy when you need to fix something around the house.

Does wood filler dry out?

Wood filler dries out and hardens over time, which makes it difficult to remove. You can’t sand off hardened wood filler and you may not be able to soften it with acetone (more on that below).

After staining or painting your project, covering up the wood putty with another coat of stain or paint is an option.

This will help hide any imperfections caused by the wood filler, but won’t make them go away. If you’re okay with this, then try using a similar color as the rest of your project so that it doesn’t stand out too much.


If you’ve ever tried to remove wood filler from wood, you know that it can be a challenge. But with the right products and techniques, there are plenty of ways to do just that.

Whether you need to soften hardened wood filler or remove it completely from your project, we hope this article has given you some helpful tips on how best to accomplish this task!
