I'm about to install a shower tray onto caperboard, sealed with SBR primer followed by a sand/cement mix to level it off.
The walls are 12mm nomoreply cement board. Due to the uneven floors, there's a gap as the floor slopes away (only a small gap though).
There is also (due to me messing up the measurements at some point...) a slightly bigger gap at one bit. I had to chisel away some of the cement board to make the tray fit in, and ended up taking out more than I thought I'd have to. The tray will be raised up hirer than it is in the photo after sand/cement mix is laid down.
How much of a problem is this/what should I do about this gap (and the other smaller one) other than filling it with sealent once the tray is down?
Thanks in advance!
