Minwax Polyshades combines stain and polyurethane in one simple step. Each coat provides rich color and lasting protection while enhancing the wood grain. This product will reduce finishing time compared with staining with one product and protecting with another. Polyshades stain and polyurethane also allows you to easily change the color of your currently stained or varnished wood without stripping. Over old varnish you can change the color without removing the old finish or hiding the grain.
