That is a great product brother Jgun,wish it was around when I did my floors.First floor I did tile setter on the job said use a polyblend morter and I went over wood.Pops [gunshots] were locked in stress's didn't crack tile but scared the poop out of me.After that I mortored in cement board and screwed down,then layed tile over that all with the polyblend mortor lot a frikin work but no pops [gunfire <lmao> or cracks.The different tile and designs [pinwheel] is bueatyful for sure. 8)
