BAL bal flex bone 2 easy Page: 8

[Subrisi]

Just read these after using flexbone. In my experience I now totally agree about floor deviation. This floor was pretty flat but 2 weeks after tiling there is a 'pop' when you tread in a certain area and I can see the grout beginning to crack. I'm certain it's due to a depression below on the new cabredeck floorboards. I will probably go back to Durabase ci matting next time (or similar) as the initial bed of adhesive prevents this issue. Not worth risking it to have to redo IMO.

PROS - quick, overlap joint is way better as Durabase system causes a hump.
CONS - Floor must be perfectly flat, need to lay out and leave overnight to flatten as edges try to lift otherwise even with correct sized tiles as per BAL recommendations.

A Durabase mat with a Flexbone overlap is the perfect solution I think.

Is it heated and natural stone? in which case I see no reason not to. if not then its not really necessary.

I've got 130m2 using flex bone later this year - the floor is anhydrite that never had the laitence removed and currently has LVT installed. I'll report back on this thread when I do it.

Has the lvt failed?

No it’s all good. I’ve already had BAL out to come spec the job.

Laitance was either removed or did not need removing then. There are so many myths and misinformation about the removal of laitance.

Laitance definitely not removed.
Agree about the myths and misinformation re laitance removal and tiling on anhydride screeds in general. It’s the reason I’ve always avoided them. Not worth the anxiety.

Apologies Ajax123,

You were quite right the laitance had been removed. After old kitchen was ripped out I could see exactly what was going on.
I finished the job end of last year. BAL guys came out to moisture test the extension and got the go ahead to crack on.
Did spend 4 days grinding the odd high spot and used 5 bags of SLC to level areas where old units were till I was happy and confident enough it was all in spec for using the Flexbone.
How did I find the Flexbone?
Expensive but brilliant product. Would definitely use again.
