Attaching concrete board to a concrete wall of condo.?
I'm replacing the shower in my condo with a custom tiled shower. One wall of the shower is an interior concrete wall with drywall attached directly to it. The wall will be damaged when I remove my current shower so I plan to cover this wall with 1/4 concrete board in order to provide a smooth waterproof surface to which I can apply tile.
I'm not sure how to attach the concrete board to this wall. I think a combination of adhesive and screws is required, but not sure what screws would be best. I need them to be flat so that tiles can be applied directly on top, withstand moisture and penetrate and hold to the concrete wall.
