Filling holes or cracks in wood can be a tricky proposition especially if you plan to stain your furniture project. Sure you can buy a wood filler, but have you ever used that stuff on your stained furniture projects? I have and I’m never happy with the results.
Store-bought wood filler doesn’t look too bad next to raw wood, but it sticks out like sore thumb when it’s stained. The wood stains dark, but the wood filler doesn’t take the stain as well and is always much lighter. Store-bought wood filler just never seems to match. It’s definitely not the attractive, professional look I want for my DIY furniture projects.
Why Make Your Own Wood Filler?
A friend of mine is into sewing and she always says the best way to match thread to fabric is to use a thread color that is darker than the fabric. She says a darker color will blend or complement the fabric while a lighter color will stick out like a sore thumb. Just like the contrast between the dark stained wood and the much lighter store bought wood filler.
Wouldn’t it be great if we could make our own wood filler that will complement our furniture project rather than stick out? We can! Not only will our DIY wood filler blend or complement our project, but it’s sooo easy to make, easy to sand, and economical!
I recently built this DIY nightstand and there were a few small gaps here and there, so I had an opportunity to whip up a batch of DIY wood filler and an opportunity to share the recipe with you!
Only Two Ingredients Needed
This DIY wood filler is made with only two ingredients. How easy is that?! First you’ll need some sawdust from the project you’re building. Collecting sawdust is easy. I collected my sawdust from the dust collection cup on my random orbit sander. I prefer to sand my furniture projects with a random orbit sander. I never use a palm sander on my projects. Skate over here to see why I don’t use a palm sander.

The second ingredient is clear shellac. This is where the saving money part comes in. Store-bought wood filler can only be used as, you guessed it, wood filler! But if you have a can of shellac you can use it not only to make your DIY wood filler, but you can also use it as a sealer or finish for your furniture projects.

Where to Use
This DIY wood filler works best on small holes (like nail holes), small gaps or cracks in wood. The DIY wood filler is not ideal for rebuilding damaged wood. For instance, let’s say your dog chewed the corner off your nightstand. Nope, this DIY wood filler isn’t the best option!
Fill the Holes, Cracks or Gaps
The wood filler is easy to work with. Just simply pack it in the hole, crack or gap. Shellac is sticky, so be sure to wear disposable gloves.
Sand the Wood Filler
One important note about shellac. Shellac can resist stain or cause wood to stain slightly lighter than wood not treated with shellac. It’s important when you fill holes with your DIY wood filler that if any shellac squeezes out, be sure to sufficiently sand the surrounding wood when you sand the wood filler.
Stain the Project
This stuff is amazing! I bet if I didn’t point it out, you wouldn’t be able to tell where the filler is, right? The DIY wood filler, just like the thread, stains slightly darker than the surrounding wood and it virtually disappears.
Have I convinced you that you NEED to make your own wood filler? It’s sooo easy to make, easy to sand, economical and best of all, will complement your furniture project. Stop wasting money on store bought wood fillers that don’t match! Make your own DIY wood filler!
DIY Wood Filler Recipe
Step 1. Pour a little sawdust onto the paper plate. I collected my sawdust from the dust collection cup on my random orbit sander.
💡 TIP: Don’t use a paper plate with a printed design like I did. The shellac pulled some of the blue color off of the plate.
Step 2. Add a little clear shellac to the the sawdust.
Add just a little at a time. If it’s too dry add a little more shellac. If it’s too wet add a little more sawdust.
We want the consistency of the mixture so that it will almost form a ball.
Step 3. Pack the wood filler in the holes, cracks or gaps. Shellac is sticky, so be sure to use disposable gloves for this step.
Step 4. Once the DIY wood filler is dry, sand it smooth. Shellac can resist stain, so if any shellac squeezes out while you’re filling the holes, cracks or gaps, be sure to sufficiently sand the surround wood when you sand the wood filler.
Step 5. You can apply your stain after the wood filler is sanded. For this project I used my favorite stain, Rust-Oleum Ultimate Wood Stain in Dark Walnut. Can you spot the wood filler? It virtually disappears!

Can I use polyurethane ingested of shellac
I would say shellac would be your best option. Shellac contains alcohol which helps the wood filler to dry quickly. I think the poly would remain sticky/gummy for awhile. Plus, you would have to be careful to remove all of the excess poly from the surrounding wood, because the poly would resist the stain and your stain would be splotchy.
Will the shellac accept stain ok and can I use Polyu over the stain with no whiteness if I apply this method of yours? wood filler do come out above the stain and finish and ruin any wood finish or stain.
Hey Carlos – You’re absolutely right. You do have to be careful with shellac because it will resist or not accept the stain. I like to use as little shellac as I can when making the wood filler just for that reason. Because the ratio of saw dust is greater than the shellac, the saw dust will accept the stain. I’m also very careful to get the filler right where I want so I avoid “squeezing” the shellac out of the wood filler onto the surrounding wood. Then I watch very closely when I sand to be sure I get any excess filler or shellac off of the surrounding wood. I’ve not had an issue with the shellac effecting the finish. Again, you want to use as little shellac as possible to make the wood filler. If you’re concerned about using this I would recommend trying it on some sample or test pieces first. Good luck and let me know how it goes.
Could you just mix up the sawdust with a little of the stain you plan to use, rather than shellac?
Hi Rick – I haven’t tried mixing the sawdust with stain, but it’s an interesting idea. Please let me know how it works out if you give it a try!
I use the sawdust with wood glue thinned with a little bit of water , and it works perfectly for me as shellac are a bit heavy on the pocket in South Africa
What an informative article! You make your instructions very easy to understand with all of the great pics. I do a lot of research online for my DIY projects. And I want to thank you for being someone I can always trust!
Hi Julie – Thank you for stopping by and for the compliments! I’m glad this was helpful for you!
My Dad refinished and repaired antique furniture for 50 years or so and always swore by using the woodglue and sawdust. The shellac would probably work better IMHO as it would be stickier.
Hi Terry – Thank you for stopping by. I think it’s all about preference. I’ve tried making wood filler with glue, but I prefer using shellac.
Hi Scott, Just A Quick Question, Can I Use Wood Filler, And Shellac As A Filler For A Project That I’m Painting. Thank You…
Hi Keoki – Yes, you could use this wood filler for a painted project.
Mix shellac, wood dust from the project you are working on, a couple of drops of wood stain that you are going to use on your project. Apply this mixture to the hole or crack and let dry completely then sand in same direction of the grain. Note; thin if needed with a few drops of alcohol or mineral spirits. Remainder can be stored in air tight container for several hours.
