Flooring problem needing help

[Barbara1]

Morning everyone.
Just ripped out the bathroom in bungalow, and are going to place Hardybackers on the wall as Iam using large wall tiles.
The problem is the floor, where I’ve taken up the old tiles it’s taken up some of the concrete floor. Some of the void’s are 10mm others 3mm.
What you recomend spot repairs with a concrete repair kit or lay 6mm Backerboards to be safe.
Also what can you get away with, with the tile adhesive.
All yer help is very much appreciated.

Just self level it. Nice flat floor. 👍

The substrate needs to be repaired with correct concrete repair kit then latex floor area to be tiled as long as it has DPM then you can install porcelain tiles

Many Thanks for the info Dave. Can you recommend a good self levelling, as there are so many out there.
Cheers

I use weber floor flex.

Prime the floor then Weber floor flex (goes up to 50mm in one hit and is fibre reinforced) or Bal level max (same as Weber but rated to 80mm).
