can you use wood filler on drywall?

Wood fillers are normally used for filling up cracks and gaps in wooden objects. But can you use wood filler on drywall? Can it really be done? And if yes, then how do you go about doing it? What are the materials required and what tools do you need to get started? Let’s find out!

There are several things that you need to ask yourself before you actually go about using wood filler on drywall

Before you start using wood filler on your drywall, there are several things that you need to ask yourself:

  • What is the purpose of the wood filler?
  • What are the advantages of using wood filler for this purpose?
  • What are the disadvantages of using wood filler for this purpose?

Wood fillers are used to add solidity and color to a surface.

Wood fillers are used to add solidity and color to a surface. They’re typically used to fill gaps and holes in walls, but they can also be used to fill up cracks and other imperfections.

Wood filler is made from a variety of different materials, including sawdust or wood chips, clay, chalk, or cornstarch. The most common types contain either plaster or paint that’s been mixed with sand or fine sawdust — this mixture increases the durability of your wood filler by making it less likely to crumble apart over time.

As the name implies, they are usually used to fill up cracks, gaps, and holes in wooden objects.

You can use wood filler to fill up holes in drywall.

As the name implies, they are usually used to fill up cracks, gaps and holes in wooden objects. They are also used to fill up gaps in walls and other surfaces like plaster, brick, or concrete.

But can you use them on drywall?

You can use wood filler on drywall. Follow these steps:

  • Apply a layer of drywall compound on the surface of the wall, using a putty knife or taping knife to smooth it down evenly. Let it dry overnight before sanding and smoothening it out with 100-grit sandpaper; then repeat this step until you’ve achieved the desired level of smoothness. If you want to paint your walls immediately after filling them (or if they aren’t very noticeable), you can stop here by just adding another coat of primer and paint overtop–but if you’d rather wait for more than 24 hours before painting them, proceed on to step two!
  • Repeat step one with additional layers of compound until all holes are filled fully (including around electrical outlets). Let each layer dry completely before applying another one; this may take several days depending upon how large your holes are and how many layers are necessary for them all to be covered up adequately

How to use wood filler on drywall.

Wood filler is a type of putty that is used to fill cracks, holes, and gaps in wood. It is a mixture of sawdust, glue, and other additives.

Wood filler can be used to fill minor bumps or dents in your furniture or cabinets. The filler does not have to be sanded down before painting; however, it does need two coats of paint for proper coverage if you want it to match the rest of your furniture. You can also use wood filler on drywall because it doesn’t provide as strong an effect as spackle or plasterboard mud would give you (which means less chance of getting messy).

Materials needed.

The materials you’ll need are:

  • Wood filler. You can get this at any hardware store or home improvement store, including Lowe’s and Home Depot. Some wood fillers have sand in them; others don’t. If you do buy one that has sand in it, try to get a color that’s close to the color of your wood so you don’t see the difference when it dries out.
  • Cloth (towel or rag). When you’re working with wood filler on drywall, use an old towel rather than a new one because the filler will stain your cloth!
  • Sponge (or cotton swab). You can also use a cotton swab if that’s all you have available at home! Just make sure the end isn’t too big so it doesn’t get stuck into any cracks while applying glue.* Sandpaper of varying grits.* Tape to hold your paper in place during application (duct tape works well).

Tools required

The tools required for this task are a few different grits of sandpaper, a paintbrush, some water, and a sponge. The amount of filler you’ll need depends on the size of the crack you’re filling. Follow the instructions on your particular brand to determine how much to use. If you can’t find those instructions or need more info, check out our guide to choosing wood filler here [link].

Sanding and smoothening

The first step in the smoothening process is to sand the area. Wood filler doesn’t sand very easily, so you’ll want to use fine-grain sandpaper. You can use any kind of sanding block you have available or just your hand if you don’t have one on hand. Once the area has been smoothed, vacuum up the dust created by this step. After that, wipe off any remaining dust with a damp cloth; if there’s still some left over after wiping it down with a damp cloth then go ahead and try using either a wire brush or tack cloth for getting rid of some more stubborn bits of filler residue before moving on to painting!

Painting the drywall.

To make sure your new paint job stays in place, you’ll want to use a high-performance glue and primer. You can look for these in most home improvement stores that sell paint.

If you’re using wood filler on drywall, be sure to choose a high-quality paint that will adhere well to it. High-performance paints are made with adhesives that hold strongly when applied over drywall surfaces; these adhesives “grab” onto the surface of the wall instead of just sitting on top of it as regular latex paints do. They also have an additional bonding agent added to them which helps keep everything together and makes sure nothing falls off over time (a common problem with standard house paints).

The bottom line – Can you use wood fillers on drywalls?

The bottom line – Can you use wood fillers on drywalls?

Yes, but make sure you sand the drywall first. You also need to use high-performance glue and paint the drywall afterward.

Be careful when selecting your wood filler! Use a high-performance glue for this purpose

You’ll want to make sure that the wood filler you choose is compatible with all of the above. Some glues are designed for use on drywall, while others are only meant to bond wood surfaces. Likewise, some fillers will only adhere properly when they’re painted over or stained, while others will be compatible with any type of paint or stain you choose. In short: use a high-performance glue and a high-performance filler!


The bottom line is that you can use wood fillers on drywall, but only if you follow the instructions carefully. If not, you might end up with a lot of problems in your home or apartment.
