Replacing a tile

    Hi,

    I need to replace a bathroom tile. The tile is 30x60cm.

    The wall underneath is plasterboard.

    The adhesive used to put up the old tiles was mapei super flexible powder adhesive.

    I've removed the tile and am trying to remove the adhesive.....but it is mighty strong stuff.

    I've wet the area of wall with a sponge , steamed it and scraped it....but it's Honda take an awfully long time to get that adhesive off as it barely budging. I used a multitool with a metal scraper/cutter to help put off the adhesive. Still....doesn't work that well.

    Does anyone have any advice?

    Is it possible to leave the adhesive on the wall and adhesive over it to replace the tile?

    The new tile being replaced will be going in the shower area. ...about waist high.


    Thanks in advance.


    Dan

    How did you get the old tile off without making total mush of the wall? If it came off that easy, how do you know the rest of the tiles are secure?

    How old is the job?

    Tiles on plasterboard in a shower area is just asking for trouble. Big trouble. I had to rip out a leaky, mouldy-plasterboard backed shower during a renovation last year, and redo the whole thing properly with cement board and tanking.

    But for now, you'll just have to grind off the old adhesive. The Mapei is good stuff. Cross-cut it into 2cm squares, but not so deep you rip thru the plasterboard, and then peel them off with an old chisel.

    If you leave it on, the new tile will probably stick out at least 4mm.

    If there's rubbery tanking layer underneath, you'll need to somehow replace that, but you'll not get a good continious seal under the adjectent tiles. No guarantees with that patch job!
