SculpWood Putty is designed to work with RotFix penetrating epoxy. The putty sticks readily to the RotFix primed surface. This combination of products provides a permanent bond with the wood substrate. However, in some instances, RotFix may not be available and the SculpWood Putty will need to be used as a standalone product.
The putty will have difficulty sticking to smooth bare wood surfaces. An effective way to get the putty to stick is to take a small amount of the mixed SculpWood and scrub/work it into the wood substrate, thus priming the surface. Once this is done, press the remaining putty onto the (SculpWood) primed surface.
