Difference Between Wood Putty and Wood Filler

When fixing a gap between a door casing and the floor, you have two main options: wood putty or wood filler. Both of these products perform the same function, but there are some key differences between the two.

Wood putty is made from a mix of sawdust and epoxy resin. This product is easy to use and dries quickly, but it can be brittle and is not very durable.

Which one you choose will depend on the severity of the gap and how much time you have to wait for the filler to dry. If you need a quick fix, wood putty is a good option. However, wood filler is better if you have more time and want a more durable fix.

So unless you have a good reason not to caulk under door thresholds – such as these negative effects – then, by all means, go ahead!
