We're about to have our deck treated & are undecided about whether to use a solid or a semi-transparent stain. Our deck is of pressure-treated wood. If we use a solid, could it chip and peel with wear. We'll be using Cuprinol. I'm not sure if it behaves more like paint or stain over time. What we don't want to have to do is scrape & remove the old when it comes time to re-apply. Anybody have any suggestions, wisdom to share?
