Well having searched around for the best preparation for tiling a bathroom floor over electric UFH I did the following:
What's gone wrong? And what's my best course of action to fix it before laying the UFH & tiles?
- - screwed down the existing chipboard floor to the joists
- bedded the heavy resin shower tray on mortar
- glued & screwed aquapanel round the tray to the rest of the floor (using BAL single part flex & aquapanel screws)
- taped the joints
- filled the gaps round the edges and covered the tape with more BAL spf
