I agree with @Localtiler . I read years ago 80% of all new floors in France were lafarge gyvlon
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...

Alan what’s your opinion on cemfloor screeds? Again a new one to me but I tiled on one recently and it was a joy.

There are a few cement based liquid screeds in the market at present. They are my competitors and whilst they have found a place in the market there are some pretty bold and dishonest claims made about them unfortunately. I suspect the would be unable to back up many of the claims they make. I have heard varying tales just as I have with anhydrite but when all is said and done I would not make a claim that could not be supported...

I think I made a thread about cemfloor last year Lee and there claims about you can tile if after a week and no need to send it, load of nonsense. The one I tiled didn't crack and it was perfectly flat.

I read the claims of tiling after 4/5 days but the rep for this supplier said 25 days. I left this one for 5 weeks, sanded it and gave it 3 coats of primer, It was up there with one of the flattest floors I’ve ever tiled.

Have you got a link to that thread Andy?

I've come across cemfloor screed on quite a few projects in the last year and I haven't had any issues yet when tiling onto it. Has anyone here heard any horror stories??
I've phoned them a couple of times asking to explain the drying times and they said because its cement based it doesn't need to be dried out fully before tiles are installed since moisture will not effect its strength. The most important factors are that most of the shrinkage has occurred and if there UFH that it has been commissioned.
I phoned BAL and asked them and they confirmed this; they also said that their Green Screed adhesive can be used to tile onto cemfloor after 7-days if there is no UFH in the screed.

There aren't many liquid screeds these days without underfloor heating.
