Hi All, I've decided to tile my bathroom floor, approx 3.6 sq meters. First time doing something tiling wise. I have taken off the previous owners cheap wooden floor vinyl tiles and are now left with the original wooden timber lengths, which are is quite a decent condition. I have been now looking into tiling the floor with porcelain tiles from B&Q - https://www.diy.com/departments/hyd...ck-of-25-l-200mm-w-200mm/3663602677710_BQ.prd 10mm thick. I have now been reading that I need to use hardiebacker boards which are stuck down with adhesive and screwed into the original wooden floor joists. This is where my issues start as I don't know what adhesive to use, flexible or not flexible. How does that exactly work when you have a 3mm gap between each wooden floor panel? I have read ardex is probably the best one to use for this but I am still struggling to work out what is best for what I need. I'm having trouble trying to source ardex as I plan to collect it tomorrow morning. Any advice would be greatly appreciated. After I work this out my tiles will be stuck down to the hardiebacker board with either Ardex x7 or Ardex X7R, which was recommended in one of another threads on this forum. Buy only If I can find a supplier near Worcestershire as I'm finding them hard to get hold of same day! Grout aswell would be Ardex I presume if I can get it tomorrow or tonight. Could anyone provide any advice if this is the right way to go?
