I have Hardibacker cement board down for ten years. Just removed the ceramic tile and mortar from it for a new tile job. Do I need to retape the joints or should they be stable at this point. The cement board was screwed into postion.
its a waste of time to tape the joints. once the substrate is combed with cement its bonded together taped or not.
Always tape joints. it acts as an expansion joint. It actually allows the expansion and contraction of the board. You never see it or feel it but its there. Any questions you can e mail me through my avatar and check my qualifications there. GL
