Slate pool deck Micah 29 Oct 2013 19:41 EDT

I have a customer that installed slate around their pool, the pool is inside, they installed and sealed with Dayton superior cure & seal with a shark skin additive for slip protection. They then covered up the floor to finish the construction. When they took the covering off, the tiles are no longer shiny and has some pealing in areas. This is a salt water pool also. I am wondering what it would take to strip this and what products would you suggest for re sealing the slate that will hold up to the salt water from the pool? Also would they be better off to use a solvent base sealer enhancer that really is not a topical? I know it would be more of a natural look but what would be they best for this situation?
