Converting a gloss varnish to a satin finish is no more complicated than sanding. The process, called “rubbing out,” scuffs and abrades the glossy varnish to take away its shine. When done correctly, rubbing out also removes any imperfections present in the original gloss varnish. But the process requires a delicate touch. Work carefully and the piece will develop a smooth, professional-grade satin finish without sanding down to bare wood.
