1. Measure And Pour Cornstarch and Wood Glue

First, take the measuring cup and pour the required amount of cornstarch you need to make the wood filler.

The amount of cornstarch you need to take to the measuring cup depends on how much wood filler you are going to make.

Here cornstarch is the ingredient that takes the place of the sawdust. Even though sawdust works differently and appears different, when making wood filler, both corn starch and sawdust do the saw.

After taking the required amount of cornstarch, pour it into the clean mixing bowl or any other plastic container which can be used as the mixing medium.

Then pour an equal part of wood glue into the measuring cup and pour it into the mixing bowl.

The cornstarch and wood glue mixing ratio should be 1:1.

Then mix the cornstarch and wood glue well using a plastic spoon.

Tip: Make sure to add cornstarch first to the mixing bowl to avoid getting wood glue stuck in the measuring cup. Otherwise taking cornstarch to the measuring can be difficult since wood glue is already stuck inside.

2. Mix Cornstarch and Wood Glue

Now mix the poured cornstarch and wood glue well using a plastic spoon inside the mixing bowl.

You can add more glue if the mixture is too rough and make thick putty with the texture of cookie dough.

Never add an excessive amount of wood glue since that will make the mixture runny.

Mix the cornstarch and wood glue well until the mixture get putty-like consistency.

After making the mixture, scoop the mixture and let it sit on the surface.

Do the pouring speed and mixing process as quickly as possible since wood glue gets hardens pretty quickly.

 When the cornstarch and wood glue are inside the mixing bowl, you should mix them quickly before the wood filler gets hardened.

Take a maximum of 10 minutes to pour cornstarch and wood glue into a mixing bowl and mix them well.

3. Knead The Mixture

Then, take the mixture into your palm and start kneading it until turn it into a dough.

Knead the mixture like clay until it stops sticking to your palm or fingers.

Make sure to do this continuously before the mixture gets hardens.

4. Add Petroleum Jelly

Now add two tablespoons of petroleum jelly to your dough-like mixture and mix with it well to reduce the stickiness of the mixture.

Petroleum jelly makes the mixture smoother and reduces stickiness.

Take the mixture onto your palm and knead using the fingers of both hands to remove any roughness inside. Stretch it, push, and pull using your fingers until it looks like a taffy.

It should be smooth and not sticky anymore.

Tip: Never add an excess amount of petroleum jelly since it will slow down the curing time.

5. Wrap The Mixture In a Plastic Wrapper

Now take the plastic warp that you use to warp foods and other stuff. Wrap around the mixture completely and press it to make the inside airtight.

6. Leave It In Plastic Bag

Insert the plastic-wrapped mixture into a plastic bag. Then air seal by squeezing the air in the bag and leave for 24 hours until it gets fully cured.

Then, clean all the tools you used using paper towels and close the lids of wood glue properly to stop them from hardening.

After 24 hours, take the mixture from the plastic bag, unwrap and warm it a little before using it as a wood filler. Simple as that!

That’s how you should make a DIY wood filler easily without sawdust.
