What was the sign stained with (oil based stain or water based stain) and how long ago?The Hybrid Exterior Wood Protector is a penetrating oil product, so provided the sign was stained with an oil-based stain a long time ago, and it's at the point where the wood is dry and will take on more oil it might work. If the sign was recently stained, there is every probability that it will NOT accept another penetrating product on top of it.If the stain happened more recently, and it was a water-based stain, we have water-based topical products that will seal the sign and protect it from abrasion and the elements (if that is what you are after), like AFM Safecoat EXT Exterior Polyureseal Clear. This will NOT work over an oil-based stain, as water and oil do not mix.We carry sample sizes so you can test first to see if the product will accomplish what you are after.
