I thought you were looking for a minimum 75% rh for tile and i have a feeling that somebody who should know ( i think it might of been @Ajax123 ) said there was no evidence to support that by removing latence you decreased drying times
This is a quote from Bal's guide for tile on anhydride screed

Laitance is a weak layer of fine particles deposited on the surface of the screed as the anhydrite cures. This layer is too weak to tile onto and can also inhibit drying of the screed. Many of the failures we see are as a result of contamination of the https://www.tilersforums.com/forums/tile-adhesive/ by laitance – highlighting the importance of carrying out this step.

They do also state 75% relative humidity, but Fball say it ok at 85% using their product.

@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 .

The ball advice is old advice. Newer information independentlybtested tells usnthag actually the licence does not significantly affect drying especially when force drying with underfloor heating.

I guess it it were blocked pores we could get some clearasil on it...

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.

Currently Francis Flower Ltd. Been here five years. We supply around 75% of the UK demand for flowing screeds and are by far the biggest anhydrtie supplier. Six years prior to that at Gyvlon, nearly 4 years at Lafarge as specialist screeds manager and 5 at a small independent supplier prior to that.
