Chipboard

[pebbles]

Hi all
just a quick one guys (or maybe not) but can we finally put to bed the best way to tile over water proofed chipboard.
i have used a few methods over the years and touch wood no probs but it seems now that customers with new floors are arguing when I tell them that it has to be overlaid because the builder said it would be fine.
they seem to think the the tiler (or not tiler) that they have had another quote from tells them they don't so they think they are being ripped off by me which usually leads me to tell them to use him but don't call me when it fails.
so let's have it in black and white from all over the uk so I can print of and show them who's right.

Cement boards glued and screwed, no exceptions. I would walk if I was told I couldn't do it that way.

When quoting backerboard or tanking I always tell the customers to do there own research online and most of the time I win the job because I have been the only one to mention it

Just remembered today that last year I fixed 600x600 porcs to chipboard (not P5) that was heated (polypipe under-floor).
After discussions with Kerakoll I used H40 Eco Rapidflex, making sure that the floor was well braced and I got 100% coverage.
I went back yesterday to repair a bit of wall grout in the bathroom and the floor is a-ok still.
Rapidflex is NOT an S2 like fastflex - felt just like a normal adhesive in use.
