how to remove old wood filler?

When it comes to removing old wood filler, there are many different ways to do it. It can be a bit of a messy job depending on the type of filler you used in the first place, but once you’ve got it out, you’ll be glad that you did! Here’s what we recommend:


If you’re dealing with wood filler that’s been on the surface for a while, you may have to sand it down before you can remove it. Sanding is best done with fine-grit sandpaper (60-100) and a sanding block. This will help avoid damaging the surrounding area while removing any rough patches left behind.


Handplane: A hand plane is a tool used to smooth wood. The hand plane can remove the excess wood filler, deep scratches, dents, ripples, and dings. This tool is often used in combination with other tools to achieve the desired results.


To remove the old wood filler, use a scraper. If the surface you are working on is flat, use an angle-head scraper.

Putty knife

  • Use a putty knife to scrape off excess filler.
  • Use a putty knife to smooth out the filler.
  • Use a putty knife to apply the filler.
  • Use a putty knife to apply a second layer of filler.
  • Use a putty knife to apply a third layer of filler

Heat gun

A heat gun is a tool that uses heat to soften materials. Heat guns are used to remove the wood filler, paint, glue, and wallpaper. The idea is that you hold the gun about 1-2 inches from where you want it to be softened, then you apply enough heat for long enough to soften that area of the material.

Heat guns can also be used for carpet removal by putting the nozzle directly on top of carpet fibers and running it along the edge of your carpet until they completely melt away (be careful not to let go of your grip on the nozzle though!).

Drill and sanding drum

If you’re trying to remove the old wood filler, it is possible. You’ll need a drill and a sanding drum attachment. The sanding drum will remove the old filler while leaving the sharp edges of your new piece intact.

Wood filler alternatives

  • Use a filler that matches the wood. If you have an old piece of furniture, use a filler that matches the wood. This will make it much easier to blend in the new wood filler and make it nearly invisible.
  • Use a less toxic alternative for filling holes in your home. There are many chemicals used in today’s world that can be harmful if used improperly or with too much exposure to them over time. One example of this is polyurethane foam, which can cause respiratory issues when inhaled or in contact with the skin directly over prolonged periods of time. If you need to fill holes or cracks in your home but don’t want any potential health risks associated with polyurethanes or other synthetic materials, consider using natural products like cotton balls or wool felt discs instead!
  • Use an easier application method than trowels and putty knives: Many people think they need something like this because they want their repair job done quickly—but what about safety? Using these tools can lead to injuries due to improper technique (or lack thereof), so think about alternatives such as sponges instead! They’re easy-to-use tools

Chemical strippers

  • Use chemical strippers, but be careful. Chemical strippers are the best way to remove old wood fillers without doing damage to your furniture. Test the chemical stripper on a small area first, and use protective gear like gloves, goggles, and long sleeves if you can.
  • Apply the chemical stripper with a brush or pad. Brush or pad the product onto the surface of the wood filler in an even layer, working from top to bottom (or side to side), until all traces of it are gone.
  • Scrape off excess material with a putty knife or scraper after about 10 minutes for high-quality results; otherwise, wait 20-30 minutes before scraping away any excess material that remains on your surface as this helps prevent damage from occurring during the removal process

Paint remover

A paint remover is a chemical stripper, and it’s usually applied with a brush. It’s not just for paint—it can also be used on wood that has been painted with oil-based paint.

However, you should only use this method if the stripper specifically says it’s safe on painted surfaces. Some strippers are not meant to be used on anything other than raw wood or metal, so read the label carefully before applying!

Steel wool and mineral spirits or lacquer thinner

  • Before applying the solvent, clean the surface with steel wool.
  • Use a rag or paper towel to apply the solvent liberally over the filler.
  • Use a wire brush to remove any residue that remains on the wood.

These tools will let you remove the old wood filler.

  • Screwdriver
  • Utility knife
  • Sanding block with sandpaper
  • Chisel
