I have an exterior staircase with wooden rails and treads that is extremely weathered. I need to patch, prime, paint and possibly seal. What are the best brand and type paint and/or sealers to use that will help protect against the elements? Do waterproof paints work well? Does a clear lacquer like Permalac work and can it be applied over paint? Thanks for your expert advice.
The best approach is to scrape and patch, then prime with Sherwin Williams Oil Base Exterior Wood Primer, then finish coat with SW Porch and Deck Enamel (color of choice)… forget about all those other options that you mentioned… just make sure you have at least 50F over nite for 2 consecutive weeks for proper curing… Good Luck!
