Yes, it is possible to use a wood filler on drywall. It works perfectly for patching up small holes in the drywall.

However, it may be challenging to smoothen like a standard drywall repair material. The surface of the patched area will be rough after applying the wood filler.

The area won’t blend with other smooth and flat wall parts. You must spend a long time sanding the spot to align it with other sections.

At the same time, you may have to wait for hours until it completely dries and all the dust settles before sanding the spot.

Sometimes, dust particles might take several days to settle in a low-humidity room, especially without fans running.

This problem is common with lighter-colored drywall and dark-colored wood fillers. The patchwork may look rough and disfiguring.

Should I Use a Wood Filler or a Spackling Compound for Drywall?

Using a spackling compound instead of a wood filler for drywalls is best. Although they have similar functions, the spackling compound is perfect for patching drywalls.

The primary purpose of spackle is to fill holes made by nails and screws in drywall. It is also suitable for fixing minor blemishes in drywall. 

It is a quick-drying adhesive that easily blends with the drywall. Spackle forms a perfect consistency with the drywall.

Sanding down spackling compound on drywall gives you a smooth and even result. You only have to paint the patchwork to match the rest of the wall.

On the other hand, wood filler is suitable for patching gaps or cracks in the wood. It fills holes and fixes blemishes in wood surfaces.

You only have to apply and sand it down to get a smooth and even result. Then, you can paint the spot to match the rest of the wood.

Although you can use wood filler on drywalls, it doesn’t give the same result as spackle. Wood filler is only perfect for patching small holes in the drywall.

Using it on a large hole in the drywall damages the aesthetic effect of the piece. The wood filler won’t blend, and it will disfigure the wall.

Other features make the spackling compound a better patching material for drywall than wood filler.

Is Drywall Putty the Same as Wood Filler?

Drywall putty is different from wood filler. They both serve different purposes, each of which has its unique quality.

Drywall putty refers to a product designed to patch and repair drywall, while wood filler refers to a range of products designed to patch and repair hardwood.

Although they have different purposes, you can substitute drywall putty for wood filler in small unpressurized surfaces and indoor applications.

In addition, drywall putty is suitable for filling and smoothing joints of adjacent drywall panels. It is like the cement of drywall and smears easily into the gaps in the seams.

It has a goo-like consistency that makes spreading and blending easy. On the other hand, the wood filler has a mush-like consistency that allows you to spread it all over wood cracks.

However, drywall putty and wood filler require time to dry before you can sand down the surface to get an even result.

Wood filler may dry faster, but the duration depends on factors like ventilation, humidity, temperature, and product quality.

Drywall putty may dry faster if the conditions are unfavorable against wood filler.
