Not sure I have the right Thinset, thoughts?

[jpb116]

Hi all, I'm ready to put down my shower base which is a one piece molded presloped tile ready deal. The manufacturer recommends a latex modified thin set as a base. I also understand that I'd want to use a latex modified under my durock for the tile floor. I just picked up a bag of thin set which is labeled "polymer modified". Now I'm questioning whether I bought the right stuff. I'm not a big fan of the premixed products because of past experience. Do I have the right product? Thoughts?

The only thing that the premixed stuff is good for is dry areas with smaller tile. It also costs about 2-4x the cost of the real stuff.

Yes, you have the right stuff.

And you're right to distrust the pre-mixed - the premixed isn't actually thinset, it's mastic.

Yeah, I know... and they ought to be sued for false advertising.
