: Would like to get some feed back on Bosticks Ultra -set on how well it isolates cracked slabs. Worse or better than the other membranes on the market? I usually use ECB membrane by NAC or equal but am in a pinch and need data on it's reliability FAST! Any help would be appreciated.

Mike,
What is the application ? We have used it primarily over clean surfaces where waterproofing was required. If you like troweling caulk it is great. If I had a chopped up room it is easier. For crack suppresion I would use something else. While I am not aware of any problems with jobs we have ever done, I am much more comfortable with a membrane where there are 3 surfaces to distribute the dynamic loading that occurs with crack suppresion. Scrim and bonding layer, sheet, and tile bonding layer to scrim is a better bet for performance.
