Floor tiles lifting after laying. Please help

Keraflex Maxi is suitable for Ply

Why would you need to use Rapid Set?

moisture content and the way it sets

moisture content and the way it sets

Not heard that before, thanks. I always thought that because a cement based addy doesn't use dispersion to set, that even slow set would be ok for wood. So is no slow set ok for wood even though Mapei say Keraflex Maxi is?

I would be looking at that floor first, It sounds suspect to me, go over it with a fine toothcomb and make sure their is no bounce at all, you must use the correct addy, do you know a tiler that could give you some info by looking at it for you, you have wasted money already on addy already, if your definately not getting a pro in to do it then a few quid as a tip for a bit of knowledge seems a small price to pay to get you on your way ( i'm a poet )

Bal flex is not rapid setting adhesive and is absolutly fine for timber floors though it is recommended that a primer is NOT used prior to fixing, if you want a faster set then bal rapid flex is the way to go but it does not have to be rapid setting for timber floors just flexi.

But if you can see the floor flexing when you press on the trowel then you have a deflection problem with the boarding which will need sorting first.
