How to Repair Cracks in Wood Doors

Updated February 21, 2017

Older homes often have solid wood doors.They can definitely add a certain charm and sophistication to your home that engineered wood or other door materials cannot match. However, the overall appeal of a wood door in your home might be diminished by the appearance of an obvious crack in the wood. If this happens to you, there are ways you can handle the crack and repair it so that your wood door becomes as good as new.

Try 100-grit sandpaper to repair the crack in your wood door. Coarse sandpaper can sometimes be enough to repair very minor cracks that look more like scratches in your wood door.

Fill in the wood crack with some wood shavings of a similar colour if sandpapering alone wasn't enough. Use tweezers or needle nose pliers, depending on the size of the crack, to fill it in with wood shavings. It's OK if they peek out of the crack a bit.

Coat the wood shavings with liquid glue, getting the glue well into the crack and over the wood shavings. Allow it to dry.

Use the 100-grit sandpaper to sand over the wood crack and shavings. Make sure the surface is completely smooth before continuing.

Apply a wood epoxy filler that matches the shade of your wood door over the top of the smoothed out wood shavings. Apply one thin coat using a flexible plastic applicator and then let it dry completely.

Apply additional coats of the epoxy filler if necessary. Sand down the wood door using first 100-grit sandpaper and then finer and finer grits until you reach 320.


Now that the crack in your wood door is repaired, you can apply a wood stain that matches the door.
