Anhydrite screed........

[One Day]

Loose lay. Brilliant in theory and in Germany where they can actually screed a decent floor.
I am sick of turning up to these wonderful liquid screed floors only to find they've been installed by members of the Muppet show.
So who is going to fix large format 6mm porcelain onto an unbonded mat, given the potential ups and downs on a badly screeded floor?!

This would have flown through it

Do you sell them Cranbrook?

course I will Malcolm.

They won’t actually spec thin tile anyway, thankfully

thought you'd never ask

But no I actually don't, I was so impressed with it and I just want to share the love

Ok fair enough, so we won’t be hitting you for sponsorship fees then.

No advertising or plugging companies on here, BAL offered me £1000 to push their new mat but I had the resilience to say no!
Resilience like their new quick install mat onto any sound surface saving time on preparation and savings on materials.

On the subject of anhydrite a mapei tech guy was on site the other week testing the relative humidity of the living/dining room floor for the lvt installers.As I had already tiled the hallway and landing I told him the reading on my hair hygrometer read 62 % around three weeks previously so the chances are it should be good to go .he asked me what I took the reading with and when I explained he immediately told me the only way to get accurate readings on these screeds was with a carbide bomb test.
I argued the case but he kept insisting the hair hygrometer was not suitable for gypsum based screed.have I missed out on a new finding that proves they're not accurate ????? Hoping Alan jacksonc an advise

@Ajax123 generally suggests a carbide bomb test I believe.

 

[Ajax123]

There are 3 tests that can be done. Oven dried sample which is usually lab work so dispute territory. Hair hygromerer which is fine provided it is done correctly...many many hygromerer are incorrectly calibrated or used inappropriately. And carbide bomb which is the quickest. my preference these days is the carbide bomb. Indie some training for mapei a while ago and stressed this point so thats probably where it has come from.

Not easy things to source tho Alan, can you point us in right direction?

 

[Ajax123]

I think mapei may actually sell them.... maybe that's also an incentive for them. You could try screed giant as they sell most things screed related.

 

[Ajax123]

They're not cheap

I've always used the hair hygrometer as instructed by yourself Alan ,so I know it's being used correctly.being incorrectly callibrated worries me a bit.mine must be three years old by now.probably used around fifteen to twenty times .time to start looking in the carbide bomb test I think.cheers
