DIY wood filler: step by step instructions

Step 1: Collect sawdust

Collect enough sawdust from the type of wood you are repairing. If you don’t have enough, make more by sanding the same piece of wood until you collect enough.

Step 2: Mix the filler

Place sawdust in your mixing bowl and slowly add wood glue while stirring. Start with a 1:1 ratio of wood glue to wood glue and adjust as needed.

Continue adding the binding agent and stirring until you achieve a putty-like consistency. The filler should be flexible and easy to work with.

Step 3: Check compatibility

To make sure you have the right consistency, apply a small amount of filler to a hidden or obscured area of ​​the wood. Determine if it matches the color and texture of the wood.

Step 4: Apply wood filler

Using a putty knife, apply DIY wood filler to the area you want to repair. Make sure it is pressed firmly into any gaps or voids.

Step 5: Leave it to dry and cure

Drying time will depend on the binding agent used. Wood glue mixes dry in a few hours, while epoxy resin can take longer.

Step 6: Sand and Finish

Once the filler has dried and cured, sand the repaired area until it is smooth and flush with the surrounding wood. You can then finish the wood with wood stain, paint or a clear finish to match the look of the wood.
