does wood filler work on drywall?

Wood filler is one of the most common home repair materials. It’s also one of the easiest to use and most effective for certain jobs like filling in holes, dents, cracks, and other imperfections on wood surfaces.

But does wood filler work on drywall? The short answer is yes — but it depends on what kind of wood filler you have.

Can I use wood filler for walls?

Yes. Wood filler works for walls and ceilings, but only when you use it properly. You can use wood filler to fill small holes and dents, cracks, nail holes, and even screw holes in drywall.

To do this, first sand the area with fine grit sandpaper (220 or higher). Then vacuum off any dust that remains and wipe down the area you want to fill with acetone or mineral spirits (something like Pledge).

This will help prevent your wood filler from sticking to anything else once it’s applied—you don’t want your patch job getting ruined by something as simple as a piece of dust!

Next, apply some glue (like Elmer’s) over the entire surface where the old wall meets its new self; wait 10 minutes for everything to get good and tacky before pressing down your wood filler into place.*

Once it dries up nice and hard after 24 hours or so then take another pass over it with 220-grit sandpaper just like before; then repeat one more time (three total) until all signs of bleeding have stopped coming through onto whatever color coatings come next.

Can I use wood filler instead of spackle?

Wood filler is not to be confused with spackle, which is a different product. While both products are used to fill holes in drywall, they have different applications and different qualities.

The primary difference between the two is that wood filler is less flexible than spackle. This means that when it comes time to cover large areas of damage or repair holes in your drywall, you may find yourself better off using spackle rather than wood filler.

However, if you’re looking for something more durable than spackle but still want the flexibility of being able to sand it down after it has dried without harming your drywall (as can happen with some commercial-grade patching compounds), then using wood filler might be right up your alley!

What to use to fill holes in drywall?

The best wood filler for drywall is polyester resin so you can fill holes in paint-grade sheetrock with ease. It’s best to use polyester resin to fill holes in wood because it dries harder and is more durable than most other types of putty. That said, there are some situations where polyester resin isn’t the best option:

  • When working on antique furniture or other items made from rare materials (like mahogany). In these cases, oakum might be a better choice.
  • If you’re looking for something that will be invisible once dried—polyester resin doesn’t quite achieve this level of invisibility due to its shiny appearance (although some brands do produce products that are closer).

Can you use 2 part wood filler on walls?

Yes, you can use 2-part wood filler on walls. You need to use a special type of primer or else it will not stick.

If you’re going to use 2 part wood filler on your walls, it’s best to get some help from someone who has done it before. This way, they can tell you what kind of primer you need and how many coats of paint you should use.

Is it better to use wood filler or caulk?

Caulk is a better choice for small holes and joints. Wood fillers are better for large holes, edges, and corners. So if you have a hole that’s about the size of your finger, caulk might be the best option.

If you’re patching up an entire room or wall though, wood filler would probably be more efficient overall to use because it fills in larger areas at once and has less drying time than caulk does.

What is the difference between wood filler and putty?

You may have wondered what the difference is between wood filler and putty. Putty is a common term that refers to a substance used to fill holes in wood.

Wood filler is also a material used on wood (like putty), but it can be used for different purposes depending on its consistency and texture. Putty is typically made of clay, whereas wood filler is composed of sawdust or sawdust mixed with glue or other binders.

Wood fillers are often categorized into two types: thickened and thinned formulas that can be painted over after application, depending on your preference.

How long does wood filler take to dry?

Wood filler dries in 2-3 hours, depending on the material you use. You can tell when it is ready by lightly scraping your fingernail across the surface of the wood filler and checking for bits of loose material.

If there are still bits of loose material present, let it sit longer before sanding. If this doesn’t work, apply another coat of wood filler and wait again before sanding down your patch job

Do you need to prime wood filler before painting?

Wood filler is a drywall product that you can use to patch holes, gouges, and dents in your walls. The best thing about using wood filler is that it’s fast and easy to apply, but if you want the best results when painting over the top of the wood filler, then priming first will help.

When priming after applying wood filler

It’s important to prime any surface before painting over it because primer creates a smooth surface that allows paint to adhere better than if no primer was applied at all.

You also need a good quality primer so that it doesn’t cause any discoloration or flaking/chipping of your new wall coverings later on down the line.

The right type of primer depends on what kind of project you’re doing: If there’s no existing plasterwork then an acrylic-based paint sealer such as Dulux All Purpose will work well; this seals oil-based paints too so make sure not to use anything with waxes added like Dulux Weathershield Plus or Farrow & Ball Primers (they don’t contain any waxes).


We hope that we’ve helped you to understand that yes, wood filler works on drywall. However, it is important to remember that this material is not designed for permanent use and should never be used as a replacement for plasterboard or other types of walling material.
