[Unused Account 1]

first time for a few years ,had a twenty five metre floor ,just screed and tile for most of it ,im not a fast tiler ,i look to get it bang on but tiled it all in 6 hours because of floor being so good ,three quarter ply flat as can be ,

I love those jobs, unfortunately they don't come along very often!!

got a 200 m2 floor at the end of the month, I hope its flat

I've got 100m to do starting the 20th of this month I'll keep my fingers crossed it's as flat as your job

that's why i love anhydrite screeds!

 

[Kyle Knowles]

I've never even seen a anhydrite screed

I get quite a lot over here. You won't find more than 2mm difference on a 200m2 floor

A guy on another forum (not tiling) showed a straight edge on his floor (one of the gypsum floors) and that was like the seven seas on a bad day.

I beg to differ! I just tiled 250sqm of it and it was terrible. No extremes of uneveness but it was up and down like the Lake district.
A normally good product - Installed by idiots

Not many floors level or even near.walls the same ,bigger tiles harder to keep level

The only ones i've seen are by the same firm and although their advice about tiling them is woeful their floors are the closest to perfectly flat and level I've ever seen. I thought all gypsum screeds went in like water and were bang on. The ones i tile are alpha-hemimydrite btw

How can they be up and down like the lake district??

As @hmtiling they are liquid pumped!

I recommended a company to come in & lay an anhydrite screed, the previous ones I've tiles to were almost perfect, this one was an absolute shocker.
I had to get anhylevel to sort out sections of the floor it was that bad.

I didn't quite believe @impish as he seems to be Mr contrary. Having seen the alpha-hemihydrite ones(the only ones i've tiled) go in it must be hard work to get them wrong unless they don't all go in like water.

Mr Contrary eh?!

OK - pics or it didn't happen...
Honestly - it was as bad as 12mm out over 2m but in "waves" as if they hadn't helped it flow out over the pipes. A shoddy job from prep to pour. Tiling was a little better though.
