Anhydrite Screed

[J Sid]

andy don't be a fool it a gamble using cement on anhydrate.
just laid 50 sqmts to day on an anhydrita floor using anhyfix. it is a rapid set but as the winters coming the setting time is slower.

dave you've used anhyfix. you've said so one this site. is the reason your not recommending it as the two local suppliers WONT supply you with it and tilemaster turned your account down.
your not giving best advice to andy dave

Ray, so what your saying is Tilemaster is the best adhesive for anhydride screed, why is it the best?
So do we now take it as read, that the only opinion that matters on the subject of adhesives is yours? 🙂

No i havnt used anhyfix , i was going to but job fell through and as for your comment on me getting an account , your wrong again , i never applied for an account , it was my bro ... so get your facts straight before shooting your mouth off.

You come on here and say anhyfix is the best but wont admit how you tiled to anhydrite before gypsum adhesives came out ... Your so full of it its unreal..

There's only one way to settle this

I still use a cement based adhesive and will continue to do so as the builder insists on it. It's not a gamble if you do it properly.

since 1982 I've been doing tiling as profession. I first learnt to tile using sand and cement. ive worked on some large projects in my time .shopping centers. prisons . listed buildings such as the. natural history museum allot of these projects had some of the meanest quantity surveyors in the game. if it wasn't right you didn't get paid.
all the time I've been tiling I've been learning so my knowledge of my profession isn't just family bathrooms.

anhydrites unfortunately are here to stay and if your going to tile them you need to get it right. if you don't you are the one the customer is going to come after .
I've done a fair bit of research on these screeds and been on a course to explain the pros and cons of using them.
the course was about 8 yrs ago. my conclusion from talking to reps technicians with adhesive manufacturers is this

under no circumstances should cement based adhesives be used on anhydrite floors there's simply to much risk of failure no matter how many coats of primer you wish to put on prior to tiling. I recommend tilemaster because they give me confidence in there products. and there easy to get hold of and talk to. there are other anhydrite addy manufacturers but were I live there hard to get hold of.
weber do a anhydrite addy but its not available as yet in the uk, for some reason, so that's why they recommend there spf.

what I try to do is give best advice to people who are less experienced as me.
p s theres only one on this site that's full of it🙂

I would of thought that its best to use the right adhesive with the right substrate, i know u can use cement addy on anhydrite, it says so on the bag, it also says on a lot of stuff to PVA 1st
I would of thought all us pro tilers on here 😉, who go on about the belt and braces approach whould welcome Anhydrite addy as its the correct addy for the right substrate
if one fails with cement addy the addy manufacturer will no doubt say you have used the wrong addy

All very well using the stuff, but I've never even seen it in my area.

Ive recently laid 2 of these floors. I scraped off all the laitence, but most of it had come loose it anyway by the time the plasterers / chippys and everyone else had finished walking all over it, then hoovered it clean, then gave it two coats of diluted BAL SBR rollered on in opposite directions.

Then tiled it with slowset flexible from Topps, which is made by Palace.
Grouted with BAL flexible wide joint grey grout, and after 3 months all is still ok.
