Our salt water pool is tough on standard, acrylic based kool-deck. The last refurb didn't hold up for 3 years, so we decided to go in a different direction, opting for Rubberstone. The 600 sq. ft. project was completed in 1 day, and looks terrific. Curt and Tyler did a fine job with very few visible flaws. I will change this review to 5 stars if this material withstands the test of time, but for right now, it looks great.
