Hi everyone, After a bit of advice (isn't everyone). We need to completely overhaul our upstairs ensuite bathroom. I've managed to remove all of the tiles and the old shower and enclosure. What's left is the adhesive on the flooring. It just doesn't want to come up (as can be seen from the pics). What are my options to get this in a fit state to begin tiling? A friend who is a builder mentioned putting down 6mm hardiebacker? If I were to do this, do I have to put some form of adhesive down to level the existing floor and to attach the hardiebacker to? Is the above the best option, or are there others? Thanks in advance for all replies.
