how to make wood filler with sawdust and glue?

If you’re looking for an easy way to fill those unsightly gaps in your woodworking project, then wood filler is your best bet.

But what if you don’t have any on hand? You can always make some yourself! It’s a lot easier than it sounds, thanks to sawdust and glue. The key is mixing them together so they expand into the gaps and seal them up tight.

What can I mix with sawdust to make wood filler?

  • Sawdust, glue, and water
  • Sawdust, glue, and paint
  • Sawdust, glue, and wood filler
  • Sawdust, glue, and sand
  • Sawdust, glue, and chalk (optional)

Can you make wood filler with sawdust and wood glue?

Sawdust and wood glue can be used to make wood filler.

  • Filling gaps: To fill the gap, you’ll need some sawdust, a cup of warm water, a little bit of white glue, and some sandpaper. Mix the sawdust with warm water until it forms a paste-like consistency. Then add glue and mix well until it turns into a creamy mixture. Apply this mixture onto the gap using your finger or paintbrush, then let it dry completely before applying another layer on top and repeating this process until you achieve desired thickness or coverage in areas where there are deep scratches or holes in furniture pieces such as chairs or tables

How do you fill gaps with wood glue and sawdust?

  • Mix sawdust and wood glue in a 1:1 ratio.
  • Using a putty knife, apply the mixture to the area you want to fill. Let it dry for several hours before sanding down with sandpaper or a block of wood that has been cut into shape. If you need to apply paint, use a paintbrush to do so once your patch is dry!

How do I make my own wood filler?

Wood filler is used to fill holes and other imperfections in wood. It’s made by mixing sawdust or shavings with glue, then adding water until it reaches the desired consistency.

The amount of water you’ll need depends on the type of wood filler you’re making, so make sure to read your instructions before mixing!

What glue mixes with sawdust?

You can get your hands on both types of glue at most hardware stores. Most craft supply stores (think Michaels) will have sawdust, too.

For the glue, look for a PVA-based wood glue like “Titebond” or “Elmer’s.” For the sawdust, look for a coarse grade that looks and feels like coarse sandpaper.

You’ll also need some water to mix with the glue and sawdust mixture if you don’t have any other liquid handy.

Once you’ve gathered all your ingredients, mix them together at a ratio of 1 part glue to 2 parts sawdust until they’re well combined into something resembling wet sand.

To use it as filler for dents or holes in wood furniture or walls/ceilings/floors: just dip in a clean brush or putty knife and apply evenly over the affected area(s). Let dry completely before painting over it with primer if needed!

What can be used in place of wood filler?

There are a few different ways you can use wood filler in place of sawdust and glue.

As mentioned above, you can use paint, varnish, or polyurethane to do the job. These options work great for small areas where the color of your wood will show through.

Sawing wood putty is another option that works well with larger areas or surfaces that need more durability than just applying paint or varnish would provide.

You can buy this at your local hardware store, but if you’re looking for something quick and easy that doesn’t require any tools other than an old credit card or flexible ruler (to smooth out bumps), try making your own with sandpaper!

Just take a strip of 80 grit sandpaper and run it over the surface until any defects have been smoothed out; repeat this process until all damage has been repaired before allowing it to dry completely and coating with furniture polish or clear wax.

Does adding sawdust to wood glue make it stronger?

You can make wood filler from sawdust and glue. This is a very effective way to repair cracks or holes in wood. The sawdust helps the glue adhere to the surface of the wood, which increases its strength and makes it more durable.

The main ingredients for this DIY project are four parts sawdust (or recycled cardboard), one part white glue, and water as needed. Mix these together until they have an even consistency before using them on your project!

You can also add colorants or natural oils to give your filler some visual appeal.

How long does it take for wood glue and sawdust to dry?

While it may be tempting to put your glue and sawdust mixture in a jar and leave it in the sun, it’s not a good idea. The sun will cause the glue to dry too quickly, which could lead to clumping or cracking as you apply it.

Instead, allow your mix to sit out at room temperature for about two hours before applying it.

When choosing how long it takes for wood glue and sawdust to dry:

  • Use commercial-grade exterior wood glue that has an open time of 30 minutes or more when applied with a brush or trowel (see Wood Glue Buying Guide).
  • Use softwood sawdust for this project because hardwood is prone to shrinkage during drying times—and we don’t want those pesky cracks! Softwood tends not only to be less expensive but also more consistent when compared to other types of wood such as oak or maple; however there are many options available depending on what type of look you’re going after (e..g., white versus brown), so keep reading below if interested in learning more about these choices!


We hope this information has been helpful to you! It’s important to remember that, while wood glue and sawdust can be used as a filler for gaps in your furniture or other projects, it is not recommended for large areas of repair.

In general, we recommend using epoxy resin if you need an adhesive with strong structural properties.
