    From the posts iv'e read, you seem to be a pro with tiling. My question is, and i know i asked a similar q a while ago, a cust wants upstairs bathroom floor tiled. The floor at mo is 18mm thick 8x2 t&g floorboards. Is this suff to tile? last thing i want is grout cracking because of flex.
    Any advise?

    make sure the boards are fixed right then you need to lay 4 mm ply ontop fix it down and tile ontop

    Don't bark at me, but what is 4mm of ply gonna do to help?
  7. As a minimum you need to fix 12mm ply, screwed every 150mm.

    You need to use flexible adhesive and grouts.

    If you do a search on here you find stacks of additional info

    If i put 12mm on top of existing, it'll cause a step at the door. How'd i get around that?

    4mm ply is over engineering, I'd try some 3mm hardboard fixed with staples.

    nearnwales, are you a gippo?

    you must be a gippo, as putting 4mm ply down would actually make it worse, you idiot. It would be better to screw down whats there than cover with 4mm ply.

    You do keep me in a job though, you gippo mental case

  15. There are a number of ways of reinforcing a floor.

    I'll give you the options I use. I generally fit natural products which require more rigidity in the substrate than ceramics, so these will be slightly overengineered for ceramics.

    1/ Remove all the floorboards and replace with 18mm WBP ply then overboard this with aquapanel which is glued and screwed using rapid set flexible tile adhesive. I tend to do this if the floorboards are shot.

    2/ Remove all the floorboards and replace with 25mm WBP, bracing any joints that fall across joists with noggins. I tend to use this method if I'm building a wet room and require a seamless floor but it can be a nuisance trying to cut back all the boards around the perimeter especially if the are supporting block walls.

    3/ If the existing floorboards are nice and solid then glue and screw aquapanel directly to them. (or simply screw plywood directly to them for a porcelain or ceramic tile.


    The glue under the aquapanel is not there to adhere the two surfaces together, the screws are doing that, it's actually there to take up any voids a remove all localised movement, a useful side effect is it actually glues it very well also, this gives a similar rigidity to screwing 18mm ply over floorboards but with a smaller height increase.

    At no point do you need to use marine ply, WBP is fine.

    Aquapanel thermal is not structural, so if your using underfloor heating and decided to use this, it has to be added to any of the above options and does replace any of the reinforcement.

    mudster, would you use 4mm ply then?
  18. Maybe lining paper and double sided sticky tape - minimalist approach

    Nail the floorboards down and paint with gloss (non drip)
