Regardless of what kind of product you use, fillers will help you fill holes inside a wooden furniture, smoothen the surface and repair cracks on the floors. Once the product dries out, you will be able to sand and repaint the surface for a better finish.

What Is a Wood Putty
Putty is a substance that is typically used on surfaces that have already been stained and varnished. It is also referred to as “Plastic Wood”.
