The prices are outragous, i used GBTA for a job and it worked out double the cost of cement based.
So really guys you are confirming what makes us nervous about this whole system, the cement and the gypsum are not compatible, yet we still getting specs from Bal and Mapei saying just to prime as normal, not a mention of Epoxy anywhere, change the spec and we are on very dodgy ground if there is a problem.
Gypsum based adhesives does seem the way to go, but these do not adhere as well to the tiles as modified cement based so we are back to the problems when porcelain was introduced.
There is still lots of science, and big words, but these do not make the system very inspiring confidence wise.
It just seems very blase of the adhesive companies to stick with a spec that could very easily lead to problems.
