With all the different types of wood putties on the market, why would you ever need to make you own putty? Two reasons are possible: you are out of putty and the store is closed or you need an exact match. In either case, making your own wood filler with sawdust is a very simple process.
Gather enough sawdust to fill the palm of your hand. Make sure the sawdust is very fine, and is from the wood you are trying to match. Sanding dust works the best because the grains are much finer.
Place the sawdust on the cardboard. Make sure you are in a suitable work area for mixing.
Mix glue to the sawdust until the mixture achieves the consistency of wood putty. Carpenter's glue or white glue work best for this process.
Fill the hole, gouge or whatever problem area is in the wood with your wood filler mixture. When the putty is dry, sand to smooth. It should make a perfect match.
Do not use Gorilla glue or any other glue of this type, as you won’t be able to sand it.
