Great choice for my bathroom floor!!
As far as thin sets go, this was by far the better choice for replacing my bathroom tile! My last floor only 10 years old was cracked in places because I'd used economy thin-set & tile. This time I went with a better grade discount tile but liked the performance rating on this thin-set so I spent twice as much getting it, but feel it's going to fix my issues with cracked tiles from coming back! Right now my floor looks fantastic! Hope this one lasts for many years to come!

profitable purchase
From a Pro's prespective this is a good product at a fair price. I wish they would make it in recyclable tough plastic bags thus reducing sloppy handling punctures and waste. Product performs well .

Great mortar!
This thin set was very easy to spread and mix (some calculation is required for smaller batches). I did have 1 or 2 tiles break, but I didn't spread enough mortar on an uneven floor. When I added more mortar and a fresh tile it worked great! I feel the floor is very sturdy now. Only time will tell if the mortar helps prevent cracks.

    Excellent adhesion and flexibility
    Thinset will bond to a painted surface that has been sanded and wiped clean. That's why I purchased it. You will have to demolition the wall to get the tile off. Excellent modified thinset.

      This is so far the only thinset I will use in place of Tec brand. It is consistent and predictable. When your working on a wall you need to know your product and how it will work.

      Lumpy
      I am an amateur but try to do things right. I seamed Durock with fiber tape and FlexBond and then applied RedGard. My FlexBond had lumps in the bag so I sifted them out. When tiling I worked for 3+ hours at a time with a 1/4 bag size batch with temp around 72F so no problems with fast setting. FlexBond does skin over on the wall for over 15 minutes and then doesn't stick well to tiles. Working slow and not realizing this I may have a few tiles with minimal adhesion. Hope they don't pop out.

        Base coat over cement board, dried hard, i should have smoothed out the oops better. My next tile job will be 10+ years from now so no biggy just grind it down
