  • @Airhead : sorry for cork bathroom repetitive chat.
    Our bloke is coming round to run through the multiple jobs we'd like him to do (wardrobe in one room, pipe boxing, and get rid of the tiles in the bathroom.

    We'd like cork floor. Tiles. As they look like the best way to replace them. In an earlier post you said something about solid floors.

    Should we:
    rip all tiles up (yes)
    replace the mdf/whatever it is under the tiles (as i think that's got wet and is causing the tiles to pop up or the cement/glue has got wet and is dissolving.
    put new base down
    then put cork tiles down

    OR
    A better way?

    Bathroom is splashy.

  • Sounds like you have understood the process.
    Remove existing tiles
    Remove damaged sub floor (probably ply, possibly some kind of tongue and groove OSB).
    Fit 18mm ply subfloor fixed to joists at 200mm centres with countersunk screws
    Screw heads filled and sanded
    Lay cork tiles on adhesive recommended by cork tile manufacturer.

    You have a choice whether to remove the skirting first.

    I wouldn't under estimate the screwing down and filling of screw heads. On some floors this whole process adds a days labour. I use a 2 part filler because it worries me that a powder filler can break up but I do feel sorry for anyone who has to undo it. It's pretty normal for a thin ply layer to be attached to an exiting subfloor if it's in reasonable condition. With any glued cork or vinyl tile floor the sub floor must be very smooth and very clean when the floor is being laid. Easier to do with tiles than it is with a huge sheet of vinyl.
