          First time with tile DIYer March 2021
          I used 6 1/2" Daltile Titanium tiles in my alcove bath. I used aqua defense over cement board. I made small batches, which made all the difference, of the thin set to a paste consistency. 1/4" trowel. 1/8" spacers. Cleans well off of the tile. Sets in 24 hours but I needed to pop out a few tiles and it didn't ruin the cement board. Backbuttered all tiles. It's working out great! But I don't have anything else to compare it to but I'm a fan.

            excellent mortar
            This has been may go-to mortar for my recent bathroom renovation to secure cement board and then tile. It came highly endorsed by the manufacturer of the cement board. My only critique would be that it was challenging to mix the entire bag and use up quickly before drying. I learned after the first blunder to mix half the bag at a time to have a better mixed batch and prevent drying. Will use again!

              We are not a pros, so we do not have a lot of experience with placing glass tile, however, we have learned a lot, and the FlexBond is only thinset we've found for large format glass tile. My wife and I are putting glass tile in two showers, over a waterproof membrane, which has the potential to create a lot of issues for modified thinset. We began by troweling on a smooth layer, covering all of the walls with the Flexbond and letting that dry. Then smoothing any rough spots we made with the trowel. We did not sand it, but smoothed the rough spots by scraping with a putty knife. Then we had a porous surface to which the glass could be adhered. we used a v notch trowel (recommended by the tile manufacturer) to apply the FlexBond over the dried FlexBond surface. We combed it straight vertically, one course at a time. We also back buttered the glass tiles with FlexBond so we achieved 100% coverage on our tiles. This worked very well. We have placed as many as 10 courses without stopping, and have had no wet weight release or movement issues. We also have tried to remove a dried tile, which would have resulted in destroying the tile and or wall, so we know the bond is very good. After the FlexBond dried (usually the next day) it cleans off of the tile effortlessly. Which is likely why it's hard to find a good thinset for glass tile. The thinset will not stick to the front of the glass tile no matter what, but it will stick to the painted back very well. And it is sanded, but we have had no scratching of the tile when cleaning off the thinset. Cleaning out the grout lines is also quite easy with a linoleum knife. But do this the next day. The longer you wait, the harder it gets. After having done considerable research, and tiling, we believe this is a great product. It has performed very well. Time will tell. If you are placing large format glass tile, don't hesitate to use this product. So far, I have no negative comments, only positive.

              If I'm going to work on my house, I like to use the best available products (within reason) so I don't have issues with it in the future. That's why I chose this Fexbond product. It was easy to use on my mosaic tile. What little bit that got on the top of the tiles was easy to clean off, even after it had dried.

              Good product. Has varied application because of it's nature. Great for Tile to non-concrete sub-straits. Also good for taping the rock joints before tiling.

              is a material which is very reliable and resistant for any type of semitrailer or bitropiso is a paterial which is a bit expensive but it is worth it pressure I have four years using it on floor bathrooms and showers and I have not had any complaints from my clients On the contrary, I had good recommendations for how good and good my work is.

              Used it on wall tile in the powder room. I'm glad I read that there isn't much cost difference between this and nonmodified thinset, which also works fine. But the FlexBond had great working time. Allowed flexibility between how stiff vs. sticky I wanted it. It was really effective for leveling those pesky bows in the wall. Great thinset. My only mistake...I should have used Laticrete grout for immaculate finish, since I was so keen to get the tile set perfectly.
