I appreciate what you are saying brian, but i am not saying dispersion adhesive is no good , i said the same as pete that when it is used thicker than it should be and also when "tilers" grout to soon when using Bal wall grout (none modified) it does turn yellow or patchy in colour due to moisture behind said tiles that cannot disperse into the substrate or our through the joints ..
Just to add i am not pulling your info to say it is wrong , just simply adding to a thread my opinion , the thing is with forums is that what is wrote on your screen and read by the reader can be taken out of context in the way it was meant to come across..
Oh and yes i am opinionated some times and hold my hands up.. just call me passionate brian lol lol lol ...
So plz do not take offence..
