Marmox board, dot and dabbed onto brick, there's some flex at the edges where the board is a)slightly warped and b) where I clearly didn't put enough adhesive.
The movement is very small (maybe 1-2mm?) and it's not the whole board (board is solid) but it's on a single edge, over a 20cm-ish span but there is movement and in a place that's going to be tiled, and also it's in a shower cubicle.
There shouldn't be any movement should there? Especially given it's going to be tiled and in a shower enclosure.
I think the answer is to rip it down and start again? With a load of adhesive around the perimeter.
Side note - Marmox fitting instructions are not to be trusted, there's no way 5 dots would be sufficient!
