While the chemical formula of wood putty can damage exposed wood, wood filler is made to bind directly to the natural wood and doesn’t need stain before application.

Filler can crack as it shrinks and expands in response to significant temperature changes. Since it hardens and does not remain flexible, wood filler is an option for repairing damaged interior walls but not a good choice for exterior repairs. Once the wood filler is applied it will dry and harden within just a few minutes. There are also kinds of liquid wood filler products that fill narrow cracks and slivers by soaking into the wood fibers and binding with them in order to repair the damage. The formula allows it to take a soft and pliable form that’s relatively easy to apply. Wood filler is made up of a hardening resin solution that contains a suspension of wood byproducts. The differences between wood putty and wood filler begin with the composition of each product. Wood filler is made of wood byproducts suspended in a binder that fully hardens in minutes. Keep reading to learn more about the differences between wood putty and wood filler, as well as when to use each product. Meanwhile, a stainable wood filler is not suitable for fixing exterior damage because filler is prone to shrinking and expanding with changing temperatures. Putty should only be used on finished or stained surfaces because the chemicals that are part of its composition can be harmful to exposed wood. Both wood putty and wood filler do the job of a wood hole filler, but there are limitations to both.
