John,
You are going to need to test this claim of ball bearing thinset and report back.
We are going to need to know what percentage of tennis elbow one can expect to avoid after 1 year exclusive troweling with only tec 3N1 LOL.....
claims worth only the pencil lead they were conjured with do indeed boost sales..
It seems they rely on the nanotechnology ............ remember the BASF products -- 20 years ago -- ?
Seems that the final cure is after 21 days -- steam showers will not see grouting before that , I guess -- .

No ISO classifications , but it beats all the ANSI requirements .
