What Is A Wood Putty And A Wood Filler?

Some people use the words wood putty and wood filler interchangeably to signify the same thing.

It’s actually not the same thing. Below, we explain it to you so you can pick the best one for the job you want to do.

Wood putty

putty for surface

Wood putty, aka plastic wood, is a non-hardening pliable paste that dries firm but not as hard as a wood filler. As you can tell by its name, it’s made from plastic chemicals but also oil-based compounds and sometimes a pigment to match the color of the wood you want to fix.

As for what you can use it for, you can use wood putty to fix small blemishes such as joint blemishes or nail holes. It’s usually used for small things on finished projects. Wood putty is very useful for small holes as it doesn’t dry completely hard. You don’t need a total cure.

Wood filler

wood filler differences

Wood filler, contrarily to wood putty, fully hardens. It’s made from fibers and wood particles mixed with a thinner and a binder. When you apply the wood filler, the thinner evaporates, which makes the filler harden and dry. This creates a very strong bond with the wood, unlike wood putty.

The hardening helps the wood maintain its integrity, but it won’t help improve the strength of joints because a wood filler isn’t a true structural material. In the same vein, it doesn’t replace mechanical fasteners.

Types Of Wood Fillers 

There are different types of wood fillers, and each of them has a different impact on drying time. There are water-based and oil-based fillers. Drying times can also depend on the depth of your application. Shallow repairs tend to try faster than deep repairs, which need multiple coats.

 Here are all the details about them so that you can pick the right one for you:

Water-based filler dry times 

type of putty and filler

Water-based fillers usually dry faster than oil-based ones. They can take between 30 minutes and an hour to dry for a single shallow repair to dry. If it needs a deeper repair with several layers, it can take anywhere between two to six hours for the water-based filler to dry.

Oil-based filler dry times

An oil-based filler takes longer to dry. For the surface layer to dry, it can take 10 to 20 minutes to fully dry, but it takes longer to do a full cure or for all the layers to fully dry. 

Once you apply the first surface layer, you can wipe any excess. Once that’s done
