Knowing how to make homemade wood putty--or cabinet maker's putty, as it's sometimes called-- comes in handy when you need wood putty in a pinch and cannot get to your local hardwood store. It also allows you to put all that excess sawdust to use.
Few items are needed to create your own wood putty. If you have leftover sawdust from a previous project, you can use it. If not, then grab some boards, a table saw and make yourself some sawdust. Be sure to use only fine wood dust, not wood shavings. For homemade wood putty, there are a few different types of glue that you can use, depending on what the putty will be used for. Wood glue is a good choice since it suitable for most projects. You will also need something to mix the sawdust and glue on. Cardboard or a small disposable container works well. Also, use a small dowel or an old butter knife to mix the glue and dust together.
How To Make The Wood Putty
Gather the sawdust into the container and remove any large pieces of wood that you see. Slowly add glue to the sawdust while mixing them together. You want the consistency to be that of a workable putty material that you can roll between your fingers. Once you have reached the desired consistency, push the putty into the area you want to fill. This could be a scratch, hole or gouge. Remove any excess material with a putty knife. Allow the putty to dry and lightly sand with a fine grit sandpaper.
Remember that this putty is only made from sawdust and glue and is not strong enough to connect pieces of wood together. Use this putty for small holes and gouges only. Homemade wood putty is usually not as strong as the store-bought stuff, but it works well for small holes or to cover screw heads.
