how to make wood filler with sawdust?

So you want to know how to make wood filler? You’re in luck: the best way to fill a hole or crack in wood is with sawdust. Mix it with water, then let it dry, and presto!

Your project will be as good as new. It’s easy, cheap, and makes for a stronger repair than other homemade options like flour paste or peanut butter (yes, really). Read on to learn how you can use this simple trick at home.

How do you use sawdust as a wood filler?

  • Use sawdust to fill small gaps

Small gaps can easily be filled with sawdust. For example, if you have a small gap between two pieces of wood or trim, apply some sawdust and push it in with your finger or a flat-head screwdriver.

The sawdust will expand as it dries and fills the hole perfectly. You may need to sand down any excess that has dried after the filler has dried completely; otherwise, this excess filler could prevent the second layer of paint from adhering properly on top of it later on down the road (as seen above).

How do I make my own wood filler?

You can use sawdust and glue to make a wood filler. Mix sawdust and glue together to create a thick paste. Add water until you have the right consistency, then apply with a putty knife.

Let dry, sand smooth, prime and paint as desired!

Can you use sawdust to fill gaps?

Yes, you can use sawdust to fill gaps. Sawdust is a very good filler for small and large gaps in wood, metal and other materials.

The best way to use it as a filler is by mixing it with glue or another adhesive before applying it to your project.

How do you make wood filler with sawdust and epoxy?

The process is simple:

  • Mix equal parts of sawdust and epoxy, using your hands to mix them together in a bowl. Do this until you have a consistent, homogeneous mixture that’s easy to work with.
  • Use a putty knife to apply the filler onto the wood and spread it around evenly with the tool’s edge (do not use an old butter knife). Let it dry for 24 hours before sanding off any excess material or any lumps or bumps that may appear in the middle of your repair job; this will make them easier to fix later on down the line if necessary!
  • Once dry, use a sanding block (or power sander) with 100 grit sandpaper attached; carefully sand off any rough edges left by applying too much pressure while spreading out filler over large areas at once–this will help ensure there aren’t any craters left behind after applying another layer later on down further into project timeline where dents begin appearing again due temperature changes etcetera which causes warping etcetera… This should take about 15 minutes depending upon how many coats were applied prior versus how many coats need fixing before proceeding onward with next step(s).

4 . Next step would be using a vacuum cleaner attachment head instead whipping out dust cloths while sweeping away excess bits, especially near corners where dust tends to settle most heavily due to humidity levels, which drop significantly during winter months making room feel colder than usual even though temperature outside was normal warming temperatures up quickly once spring arrives making people forget how cold they felt earlier…

What can I use instead of wood filler?

So you have a project that calls for wood filler and you don’t have any. Well, there are some substitutes for a wood filler that can get the job done if you’re in a bind. These substitutes come in many forms:

  • Wood putty—This is one of the most popular options and it’s easy to find at your local hardware store or home improvement store. It works well on small repairs like holes in walls, scratches on furniture, and more.
  • Epoxy putty—Epoxy putty is made from two different types of epoxy resin mixed together with hardeners. You can use this product to fill cracks in wood furniture or other items with holes or cracks using a putty knife (but don’t use too much). Epoxy putty dries hard so it lasts longer than regular wood filler when used outdoors (for example: around windows). However, since it dries so hard it may not be suitable for all projects unless they only require a small amount of filling material such as cabinet doors made out of plywood which doesn’t require additional strength beyond what they already have due to their thickness (1/8 inch) vs thinner materials like drywall which requires more support due its lightweight structure without any reinforcement structure inside before they can hang anything heavy over them without causing problems later down the line when cracks develop because their shelf supports were not strong enough).

What glue mixes with sawdust?

Epoxy is the best glue for making a repair in wood. It dries hard and it’s waterproof, so you can use epoxy to fill gaps or seams in boats and other marine applications.

Epoxy also works well for filling holes in walls, floors, and ceilings. Epoxy comes in two parts: a resin (the base) and a hardener (the catalyst). You mix equal amounts of each part together before applying with a trowel or caulking gun.

The advantage of epoxy over other glues is that the resin will bond with the wood fibers while the catalyst hardens them into place permanently–so they’ll never come loose again!

How long does homemade wood filler take to dry?

The drying time of homemade wood filler can vary greatly depending on the temperature and humidity in your area, but it typically takes 24-48 hours to dry.

Wood fillers made with sawdust will dry even more slowly if they are applied in a humid environment. In this case, you may want to use a hair dryer or fan to speed up the drying process.

How is wood putty made?

The first step to making your own wood filler is to gather the ingredients. You’ll need:

  • Sawdust
  • Glue (such as white glue or PVA)
  • Water (tap water should be fine)


I hope this article has helped you learn more about the different ways of making wood filler, and I look forward to seeing your finished projects!
