BAL bal flex bone 2 easy

[hmtiling]

ok guys so far a lot of what i already know. the job is 220 mtrs on a newly layed anhydrite floor that is going to be sanded 5 day after laying the tiles are 900 x 600 x 20mm limestone just bought the adhesive its webber rapid grey deal at ctd today. the screed will be 3 weeks old when laying. its going down next wednesday and no ufh
what im asking is has any one experince of laying it dose it sound hollow and is there any movement that may result in grout cracking

Are you using flexbone on this?

 

[Flintstone]

If your using flex bone, why are you sanding ? Also after 3 weeks it will still be too wet

 

[hmtiling]

I'm more concerned about sanding it 5 days after laying the tiles

were sanding to allow the hard layer on the surface to be removed as this will allow drying to happen quicker were running 4 big fans 24hrs a day to circulate the air so allowing drying faster.
the hard surface layer slows down drying as it helps retain the moisture.

yes hoping to

the screediers are sanding it as part of there contract 5days after the screed is layed. stupid if sanding after tiling. i missed the full stop out.

Dehumidifiers will speed it up. Ask bal what %rh they allow with flexbone and get a hygrometer on it. Keep us posted on your findings

@Python Adhesives can sort flexbone and give you an m40 spec @RayTheTiler

I had a grout issue with them recently. Totally washed their hands of it. Topps, however, paid out. Their aggressive marketing and p*** poor customer service has started to grate
Thought a forum sponsor should get the nod too

I think we busted that myth some time ago, no evidence to suggest that sanding aids drying. @Ajax123

Had exactly the same . Grout issue topps paid some money but bal said there was nothing wrong with it . I wasn't happy, customer wasn't happy with grey grout in limestone but apparently in their colour parameters . Great company , but apparently just invented a new floating decoupling membrane , just blows your mind because I've never seen anything like it before . Also next week they are inventing something called the wheel .

bal will come and test for right moisture content

no evidence to show it dos not either. but air circulation dose

 

[Ajax123]

Ineed it does ray. In fact the absolute key to drying calcium sulphate screeds is air movement. This should be avoided for the first 72 hours of the screeds life but after this the more ventilation the better.

thanks 4 your views all its as clear as mud

just thought id up date, finally got the go ahead from lewis the bal rep who ,moisture tested the anhydrite floor. after 35 days finally got moisture down to 1.5 so gave us the good to go so we started yesterday with a dark gray riven limestone 600 x 900x 20mm thick 220 mtrs to lay.
1st thing about the job no sanding so after a sweep and vacume started to roll out the flex bone matting was so easy to lay and two days in we have 60 mtrs down.
i would like to thank lewis from bal for his advice and for carrying out the carbide moisture test.was worried it would sound hollow when walking on but it sounds just like any other decoupling mat floor ive done. will defo use again.

I thought one of the selling points of the 2E was that it could go straight on new screeds and will continue to cure after tiling complete. Why do we need to still do moisture tests?

 

[Time's Ran Out]

... and what happens to the 25 year guarantee if you use Weber adhesive with it?

 

[Flintstone]

No guarantee at all if you don't use BAL products start to finish and wear a BAL t shirt whilst your tiling

 

[Dumbo]

So i had it out with one of their reps , if the mat fails they will guarantee it , if you use bal products they will guarantee the whole installation. After all It does have to be of merchantable quality . The problem lies proving which part has failed .

on sand and cement screeds you can go straight one. but with gypsum based screeds they have to be 1,5 or below as moisture can mush the gypsum this reeding is a carbide bomb test

how can the mat fail its not stuck to any thing ?
