Can anyone explain or point to a proper thread as to how to deal with plastered finished walls, bonding thistle straightened walls etc. Because I just read about something called ettringite failure and it really worries me not to make any mistakes. As it happened few times i tiled over bonding with cement based adhesive, no primer. Also backsplash with ceramic tiles using tub adhesive over skimmed wall. Also if i tile over concrete screed do i always need ditra? I know for you guys these are basics, but i heard and read so many different opinions (sometimes ridiculous) that i don't know what's right. Thanks
