How to Fix a Crack in a Wooden Door?

Fixing a Simple Crack, Step by Step

In order to attempt to repair your door cracks, you’ll need to assemble a few items from your toolbox – and kitchen. Grab some baking soda, a putty knife, CA glue (a powerful fast-acting adhesive which bonds to wooden surfaces), and sandpaper. Then, follow these simple steps.

  1. First, fill the gap in your door’s crack by pouring some baking soda inside it. Continue covering the entire area surrounding the crack by pouring baking soda until every crevice is completely filled.
  2. Next, smooth the surface out with your putty knife until the spaces are all evenly filled with baking soda, and there are no gaps. Fill any areas containing baking soda with drops of the CA glue. Sand the whole area down firmly with your sandpaper to smooth the surface over.
  3. Lastly, let the door dry for a minimum of 2 hours (3 hours, to be on the safe side). When it is completely dry, paint over the whole surface of the repaired crack to match the rest of the door. The baking soda prep will ensure that the paint will settle subtly over the repair, blending in so well that you wouldn’t know the crack(s) had ever existed.

Fixing Larger Cracks

Sometimes, it isn’t so simple. Sometimes the cracks in your door are so big that the baking soda method just doesn’t work. In that case, here are some more intense methods and tools you can use.

Wax Sticks

Wax sticks are ideal for the purpose of fixing cracked wooden doors due to their flexibility. You can very easily mold the wax into the crack. Perfect for very long cracks that need a lot of filler, wax sticks are simply sanded down once the gap is filled and then painted over.

Wood Putty

Wood putty is ideal for this purpose due to its thickness and durability. It is also quite malleable and easily spreads into the cracks and fills them, blending in with the natural wood. The repair is a long-lasting one, but be sure to match the wood color correctly with your door, as there are a variety of shades available.

Glue & Sawdust

The glue and sawdust method takes a bit of trial and error to pull off successfully. In many DIY cases, sawdust does make a handy filler, so when you do have leftover shavings in the workshop, remember to save them for situations such as these. Using the same method, fill the gaps with sawdust, smoothing it over with your fingers.
