Yes PolyWhey Exterior Penetrating Stain can be applied to pine and other bare woods. It can generally be applied to plywood as well. Keep in mind, plywood is full of glues and many other substances besides wood. Test a spot first with the finish before applying to the entire project because (it's a long shot, but. . . ) glues in the plywood could potentially cause cloudiness in the finish. PolyWhey Exterior Penetrating Stain is a stand alone product, no conditioner or primer required.
