Hi there. We built our home 5 years ago. I have a large covered wrap around porch and porch steps that were painted with porch paint I bought at home depot. From what I can tell, there was no priming done. The paint has peeled up in so many places it just has to be re-done asap. painter told us he would pressure wash, sand, prime and paint it with Sherwin Williams porch and floor enamel. When I went to the Sherwin Williams store to pick a color, they advised me to use their Deck and Dock elastomeric coating made by duckback. Im concerned because from what I've ready, once this type of product is put on, its so much work to ever redo it with something else. I just want that shiny painted porch look that will last as long as possible. I know that what we should have done from the beginning is go with a solid stain but since we didn't and the surface is already painted...Where should we go from here???? I can't thank you enough for your input!
