tiling over chipboard floating floor! help needed

[CJ]

Just walked away from another floating floor.

when I first went to look at the job, the whole area had laminate down, on top of the usual green underlay fibre boards. Customer assured me the substrate was screed.

Big job as well (75m) although only??? About 20-25m was the floater.......but big enough to actually see the floor flexing when the dog walked across it. (Now laminate/under felt removed)

Tiles where special order only.......and have just had a phone call from supplier to say that there is a "restocking charge" of 20% which is going to cost the customer around £500 to send back.

whilst work isn't plentiful at the moment........my head STILL says no. Even with an extra £500 to overboard with hardi and 2 part addy.......which I'm not even sure they would accept (even though I still may walk)

This evenings phone call is going to be interesting??

Good luck!

Same here......couple of very small floaters, nothing on this size.

I tiled a 19ft hallway for a Brazilian couple about five years ago, that was T&G green chipboard, i used Bal Fastflex and have not heard that there are any problems. You could see the floor move as you walked across it (before tiles went down) i decided to give it a go (everything was explained to the customer before you all start slaughtering me) on the basis that the area being tiled was not very wide, standard sort of hallway about 4-5ft so i only really had to worry about movement across the length of the floor. Don't know about your 25m2 longer and wider area but i can tell you that after tiling with fastflex you could see the slightest movement of the tiles as you walked on it, used bal wide joint grout mixed 1/1 with GT1 and like i say i have herd nothing from the customer. Not for one second suggesting you should get on with it, just wanted to tell my story 😛rrr: but that fastflex is pretty amazing stuf.
