can you use wood filler on walls?

The answer to this question depends on a few factors, including the type of wall filler you’re using and what kind of walls it is.

Can I use wood filler on a plaster wall?

Yes, you can use wood filler on plaster walls. It will stick to the wall if it is first sanded down, and then you will need to sand it again after the filler has dried so that it blends in with the rest of your wall.

Can you use Ronseal wood filler on walls?

Yes, Ronseal Wood Filler is suitable for use on walls. However, this product is designed for use on wood, so you should be aware that using it in a non-approved location may result in damage to your wall or plasterboard.

It can also be used to fill holes and cracks in plasterboard but only if they are not large enough to cause structural damage and the surrounding area isn’t too damp.

Can I use wood filler instead of spackle?

Spackle is a putty-like material that’s used to fill holes and cracks in walls. It’s easy to apply, but it can be difficult to remove.

Wood filler is a more permanent solution. It hardens and seals the surface of your wall, making it difficult for moisture to affect the wood beneath.

Wood filler also hides imperfections in your walls better than spackle does (because it doesn’t rely on air bubbles).

You can use either one of these materials alone or combine them together into one solution.

Can you use 2 part wood filler on walls?

If the surface of the wall is made from plaster, then it’s not recommended to use 2 part wood filler.

However, if you have a hole in your wall and want to fill it with similar material, then this can work well as long as you don’t want a smooth finish.

If you do want a smooth finish then I recommend using traditional wood filler instead (link).

What’s the difference between wood filler and Polyfilla?

Polyfilla and wood filler are both plaster fillers, but they’re not the same thing. They both work to fill holes and cracks in walls, but they do it differently.

Wood filler is a putty that can be sanded down to a smooth finish (wood filler may even come with some grit pre-mixed in), making it easier to paint over or finish with oil or varnish.

Polyfilla feels like putty too, but if you’ve ever used it on a wall then you’ll know how hard it is to get an even coat!

Because of this, we recommend using only one kind of product in each application: either Polyfilla or wood filler as needed for cracks; then finish off with paint instead of additional layers because these would make your walls look patchy after drying (though if this isn’t an issue then go ahead).

What can I use instead of wall filler?

You can use wood filler on walls, but you don’t have to. Here are some alternatives:

  • Caulk: Caulking is an excellent way to fill smaller holes and cracks in your wall. The material is sometimes referred to as silicone or rubber sealant; it’s designed for waterproofing and weatherproofing, but also works great for filling holes. Unlike wood filler, caulking comes in different colors so you can match the color of your wall—and unlike wood filler, it comes in a variety of textures so you can match the texture of your wall too (for example: flat or gloss).
  • Spackle: Spackling compound is another product used for filling holes and cracks in walls (usually with a spackling knife). It’s similar to wood filler except that it dries harder than most final finishes on top of it so any sanding needed after painting or staining will be much easier if done with spackling compound instead of a softer substance like a plaster-based joint compound.

Can I paint over wood filler?

Yes. You can paint over wood filler with a brush or roller, but you’ll want to sand the surface first.

The added layer of paint will help cover any imperfections created by the wood filler and also create a smoother finish that doesn’t feel as rough when touched.

You may need to do more than just sanding, however; if you’re planning on painting an entire room or large section of wall, it’s best to use a primer first for better adhesion.

How do you smooth fillers on a wall?

Once you have your fillers laid down, you’re ready to smooth them out.

  • Sandpaper is a great way to get rid of any bumps or uneven areas that are still visible.
  • A paint roller is another great option for smoothing out the filler over the entire wall. You just roll the roller back and forth over the wall until it’s flat and smooth. This method can be faster than sanding because there’s no dust or debris flying around when you use it!
  • If you don’t have a paint roller available, try using a sponge or brush instead! You can also use an old rag that has been dipped in water; this works especially well if your walls aren’t too bumpy yet but they need some extra smoothing out before painting starts up again after adding fillers into them (which is probably going


We hope that this article has been useful and helped you understand the different types of wood fillers available.

We know that they can be confusing but we want to remind you that it’s important not just to know how each filler works, but also what is best suited for your project.

For example, if you’re looking at a smooth finish then Polyfilla or plasterboard filler are great options as they’re easy to sand down and paint over later on.

However, if you want something more durable then we would recommend using traditional wood-based products like Ronseal Wood Filler or Polyfilla instead!
