Quote:You can "pack out" tiles to work on uneven walls. It is not easy and can be messy but if it is just a small section then you can do it without too much stress.
You use more adhesive in the areas with dips and less in the areas with lumps. It involves a bit of trial and error to get the correct level but experienced tilers can get it pretty spot on every time (I am not an experienced tiler
).
Thanks for the advice, much appreciated. In the end I took the dry lining off. It was easy because the gypsum adhesive was daubed in big lumps on to block work that was probably not given any preparation because the daubs fell off with a slight knock from my mini crow bar.
So I now have two block brick walls, one of them runs out by 2 inches (yes inches) from floor to ceiling, so a bit of fancy batten work to do?
The other problem I have now is after removing the boards from where I want the wet room former, I discover the main joist (7x4) that the joist hangers are fixed to (for the right angled joists) is twisted and so forms a a high ridge. This wasn’t a problem (presumably) when it was a traditional shower tray, floor boards and carpet, but now it buggers up the level for the wet room tray. I can’t see how I can work the joist to remove the effect of the twist without moving the joist hanger top portion out of the way as I do each section.
Any suggestions welcome
