DIY Wood Filler: The Finest Wood Filler

Family Handyman

Epoxy glue and fine wood dust mixed together make a top-notch filler for dents and cracks in wood. It doesn’t shrink over the years like other fillers, and you can get a good color match by using fine dust from the wood you’re filling. A belt sander equipped with a 120-grit belt will churn out all the dust you need in 10 seconds.

Mix equal parts of wood dust and epoxy in the concave end of a pop can. Apply this homemade putty with a Popsicle stick, slightly overfilling the crack or hole, then sand smooth when the patch is hard to the touch. Pay attention to the working time of your glue; some set up super-fast!
