0254-0050-21 Platinum Multipurpose Thin-Set Mortar, 50 lb, Gray

I used the mortar to install pool tile and worked great

Perfect product! Check locally though! Found this cheaper locally than on Amazon. Plan on using more than it says it will cover.

This thinset is the best I’ve worked with. Gives adequate work time.

Had to replace tile with an installation on a very moist (at times) lower level cement floor. I used typical thinset from a big box store and my tiles never dried/set—even after a month!! This product sets solid in 24-48 hours. I am very impressed and will never use anything else for floor installations, moist floor or not!
