@Ajax123 is an expert in this field as I believe he is a tech guy at a gypsum screed manufacturer therefore probably spent more time playing with these screeds than ball and bal put together . Also I haven't seen you quote anything about improved drying times apart from your own opinion . I have never fixed ceramic , porcelain or stone tiles using f.ball tile adhesives , have you ? As regards your other post maybe the floor is shiny because of the primer he has used .
Expert? Well I know a lot of stuff but still learning. Have been around these screeds for almost 20 years. Heard most of the rubbish spoken about them and there's been plenty of that over the years.
