I'm trying to figure out if I need to remove the flooring before laying down the Wonderboard. This if my first time laying tile, I just finished removing the vinyl tile.
Items I purchased: Wonderboard, Versabond Thinset, notch trowell 1/4, bucket and mixer extension for my drill.
Not sure if this top layer was added to help even the floor for the vinyl time it had before. I'm adding wonderboard and a ceramic tile. Just trying to understand if this layer needs to be removed before I do any work.
Thank you ahead of time.
