The cement board is pretty straight and vertical. The rest of the bathroom is not!
I am wondering how best to finish off the end of the cement board, next to the door architrave? I could just squirt some expanding foam into the gap, but that still leaves the edge of the cement board exposed.
One possibility is to rout a big groove in a length of timber and slot that over the end. I was thinking of tiling it first, then the wood can go over the edge of the whole lot.
Any suggestions most welcome, please.
