I have a covered deck that was originally stained with Pittsburgh Ultra advance semi transparent acrylic oil formula.It is in really good shape and most of it still has a sheen.However I need to re-stain some areas that catch more sun.I would prefer to do the whole thing.What is the recommend treatment for the areas that still have a sheen?I plan on using the same stain that was originally used.
I would check with Pittsburgh on this one as we do not use their products in our restoration jobs. It should be on their label as to what prep is needed for reapplication.
