Floor tiles lifted on calcium based self level floor

Just because it's been professionally sanded, doesn't mean it's been done properly, most of the Anny screeds I go to, they say, the company came back sanded it so it is fine to tile, when in fact it's not, sand them too early and more latence will settle, and the guys screeding don't care about the prep a quick go over with light machine and they think it's fine, when in fact again it's not, same with proper dying times, they tell customers it will dry in X amount of time, when we all know it's only dry when a proper hygrometer or other test is done and gives sufficient reaults. Knowledge on these screeds is key

They have to be sanded in the 1st few days or he latency gets too hard ?

You can sand these screeds at any time, yes they are softer in the early days but still sandable after many months.

Aye I know mate, but doesn’t it help with the drying process as well ?

According to our industry expert @Ajax123 , no it doesn't.

 

[Flintstone]

No, I think that's an old wives tale.

Its a funny old world we live in, rules change dsy to day

I’m old school, I pee on them and time how long it takes to dry then refer to the water table graph, as per saturation point!

yes they do. They did it over here for a while but the market did not ask for it enough to warrant keeping it. Shame really.

probably a bit optimistic. Probably closer to 50%. Around 25% of new floors in the UK are anhydrite. that number is increasing year on year. 5 years ago we reckoned it was about 15% and 10 years ago only about 5%. long may the growth continue. It pays my bills...
