The Vermont Natural Coatings PolyWhey is a self-sufficient sealer. It must be applied over a clean, dry porous surface without previous sealers or paints. If it has been sealed, stained or paint, it will need to be sanded off.Another option is our Rubio Monocoat DuroGrit zero voc exterior oil-based stain and sealer. https://www.greenbuildingsupply.com/All-Products/Rubio-DuroGrit
