Spackling On Wood Joints – Will It Work?

You’ve amassed a little pile of scraps from several previous carpentry endeavours. In the long run, you hope to make use of them, but before that can happen, you need to fill in certain blanks. Is spackle appropriate for use on wood joints, or is there a different substance required?

Wood joints can be filled, spackle applied, and any extra spackle removed with a sander. Spackling is a type of wood filler that, depending on the size of the holes you’re trying to cover or the ugliness you’re trying to disguise, may take two coats.

In the following paragraphs, I’ll explain all you need to know about spackling wood joints, from the distinction between spackle and joint compound to specific techniques. When you’re done reading, you’ll know exactly how and what to use to fill in wood.

Can Spackling Be Used as Wood Filler?

You could just run out and buy some wood filler from your neighbourhood hardware shop, but you’re already running late on your current woodworking job. If you can seal cracks and holes in wood at home, it will be fantastic.

Spackle, fortunately, can fix it! When filling wood, how do you use spackle?

To use spackle as a wood filler, follow these steps:

Reduce the number of wood flaws as much as possible using some sandpaper.
Utilize a putty knife to spread spackle onto the wood.
Wait until the spackle has dried.
It’s best to sand down the area after applying spackle so that any excess may be removed.
I’ll explain the foregoing procedures in further detail.

As a first step, smooth out any blemishes in the wood.

Although it is the spackle’s role to hide wood flaws, there are things you can do beforehand to make the process go more smoothly.

A sanding block is required for this procedure. Pass the sanding block over the entire piece of wood, paying careful attention to the trouble spots. Remove as many flaws as you can with a buffing motion.

After you’re done, wipe the wood down with a clean, soft cloth to remove any remaining sawdust.

The Second Step: Spackle

It’s time to start spackling.

Split open the spackle can. Put some spackle on the wood along the joint by dipping a clean putty knife into the jar and spreading it around. You should use only as much putty as is necessary to conceal the damaged areas.

A putty knife of the same length and width (3/4 inches) can be used for more precise work on smaller areas. Putty knives come in lengths up to four inches, so choose a tool whose blade is as wide as necessary for the job.

Putty knives are used for pressing spackle into the wood cracks.

Third, remove any excess spackle with a scraper.

The chances are high that you will use more spackle than necessary, even if you are careful. You can remove the excess spackle from the wood by running a putty knife across it. Simply return it to its original container for future use.

4. Allow the Spackle to Dry

Once you’ve finished applying the first coat of spackle, you must wait for it to dry. The spackle may not be totally dry for up to 24 hours, but it will be dry to the touch in that time. The drying times for spackle should be determined according to the directions on the spackle container.

Phase 5: Smooth the Wood

Once again, using your sanding block, remove any excess spackle. In order to remove all of the sawdust from the wood, wet a cloth and wipe it down well.

Sixth, Evaluate the Wood

When you’re done sanding, examine the wood from every possible aspect. Do you think the spackle successfully bridged the gaps in the wood? If so, that’s fantastic! It’s safe to say that this part of the project is finished.

Seventh, apply spackle again if necessary.

The same applies if you aren’t completely satisfied. Expert woodworkers know that two or even three coats of spackle are necessary to completely seal any holes in the wood. If you need to, continue with the above procedure.

Can I Spackle Instead of Joint Compound?

A coworker in the trade may have recommended joint compound over spackle for bridging visible cracks in wood. Before I suggest joint compound over spackle, I need to make sure you understand the difference between the two.

Smaller sections can get away with using spackle instead of joint compound. Joint compound is preferable for large holes and joints.

Putty is a common construction material, while spackle is designed specifically for use on plaster, drywall, and wood. It can fix small flaws and holes on the surface but not big ones. Gypsum plaster, the primary ingredient in most spackle, is produced by binding together glue and hydrated calcium sulphate.

However, drywall compound is another name for joint compound. As with gypsum, this too is a dust form of the mineral. When the dust is mixed with dirt or water, the resulting substance has the texture of buttercream icing.

Comparing Spackling and Joint Compound
In the last section, I demonstrated that spackle may be successfully applied to wood. You can also fill wood holes and cracks using joint compound if you choose, but how do you do that? Please follow these helpful instructions.

1 Get Ready to Make Joint Compound

Using water with the gypsum powder that is joint compound is less dirty and more convenient. Your product’s box will instruct you on the ideal proportion of water to powder to use. Please use that proportion, and mix the ingredients until they form a paste.

Second, spread the joint compound with a putty knife.

The following procedure is similar to what was done previously, so it should be easy to follow along. Spread the joint compound on the wood using a clean putty knife. Take care to work the compound into the wood without leaving a thick layer on the surface.

Third, wipe away any excess joint compound with a wet cloth.

Extra joint compound can be removed with a putty knife, although a damp, soft cloth can be used on the wood if necessary. Don’t wait for the compound to dry before attempting removal.

Time for drying is the fourth step.

The compound should be allowed to dry for an extended period of time, ideally the rest of the day and into the next morning.

The fifth step is to sand away the leftover joint compound.

When you wiped down the wood with water, did you fail to remove all of the joint compound? Nothing to worry about, really. Sand the wooden block with 240-grit paper. To avoid scratching the wood, sand in the direction of the grain.

One application of joint compound, as opposed to spackle, should leave your wood smoother and with fewer holes. If the wood’s appearance isn’t satisfactory after the initial coat, further coats might be applied.

Can I Paint Over Spackled Wood?

The advice in this manual helped you spackle the wood seams without any problems. You spackled the wood with the intention of painting it, but now you’re not so sure. It spackled wood be painted?

Spackled wood can be painted immediately; there’s no need to let it dry overnight. Spackling dries rapidly, allowing for same-day painting.

I’d want to elaborate on this a bit. Spackle, you may recall, requires a full day to dry. As I mentioned earlier, however, it is typically dry enough within an hour or two.

Wait two hours, maybe more if the area you spackled is particularly large. However, if you’re only spackleing a tiny area, you can skip the waiting period and get to painting in under an hour. Good news for you, as you can also paint the spackle-treated wood in that time frame.

Painting wood is an excellent method of disguising spackled wood. Painting over the spackled sections should be as easy as painting over the untreated wood.


Joints in wood can be repaired by applying spackle or joint compound to fill in cracks and dents. A putty knife, a clean rag, and a sanding block are all necessary tools for this task. Spackling wood joints doesn’t have to put a damper on your day, as the wood will be mostly dry in an hour.
