For that reason, it is best to use an elastomeric, crack-prevention membrane to both seal the floor and protect your tile installation from failure. These membranes prevent water from seeping up through the concrete and into the mortar as well allowing the thinset to cure and preventing future mold or mildew growth.

Asked By: musicamante Date created: Jun 10, 2022

2 Answers. The thinset and mesh tape are to strengthen the seams. If you are going to tile over the cement board, you should tape the seams. If you just want to leave the corners untreated that will probably be fine, because that seam won't split the center of a tile.
