I mixed this mortar as directed, was a nice smooth, thick paste consistency that went on beautifully. Checked it the next day, and some globs that had fell on the ground i could break and crumble easily. I also could pull the kerdi off with no issues. I am concerned if i put tile on iit, the tile weight would pull off the kerdi from the wall. Did i do something wrong? I was told by the manufacturer that i should be able to tile 24 hrs after application.

CUSTOMER REVIEWS

Rated 2.7 out of 5 by 6 reviewers.
Rated 2.0 out of 5.0 by Don't use this, buy a better brand This stuff is horrible, used for one wall, may have to redo it because I just don't trust it. Going back to laticrete. January 27, 2016
Rated 4.0 out of 5.0 by Worked well I used this mortar based on an on line suggestion on a tile site. It was much creamier and easier to mix than other mortars I had used. It created a great bond between my wall tiles and Schluter membrane. I had a hard time removing tiles to check for good coverage! So far so good! Had no trouble with odor mentioned on a review of the white mortar made by same manufacturer. June 13, 2015
Rated 2.0 out of 5.0 by Caution - ignore the directions Used exactly the amount of water specified on the bag and it was too runny. It would not hold the tile in place well and the mortar spread too much and came back up through the joints creating a mess. Probably a rookie mistake, should have started with less water and added more if needed. December 13, 2014
Rated 5.0 out of 5.0 by Great Product! This product pairs perfectly with the Ditra underlayment sold at Home Depot. I used Versabond under the membrane to adhere to the plywood and this between the tile and membrane. It applied easily and held ridges well. It also has a decently long work time, so you don't have to worry about wasting mortar. Cleanup was a breeze as well, anything that was accidentally dropped on the tile came right off. I would highly recommend this for a easy install! The tiles in the photo are also from Home Depot, MSI Onyx Sand 12x24. August 3, 2013
Rated 2.0 out of 5.0 by Nice looking bag The mortar was located 70 miles from where the Schluter materials were purchased. 140 mile drive to purchase the mortar for an installation. July 2, 2013
Rated 1.0 out of 5.0 by gray bag no good had to do project over had my wife upset at me December 17, 2012
