    Afternoon all,

    I'm having a new bathroom fitted but I'm currently at the stage of ripping all the old stuff out first. I've taken the bath out and all the tiles around it.

    The walls are constucted using flower pot bricks/grey blocks, this is then coated in cement render, then plastered, then tiled.

    When taking the tiles off the wall - various parts of plaster and render have come off with them leaving me with a mixture of surfaces. I'm after a bit of advice on how to proceed. Do I knock all the plaster off to the render. Knock all the render off to the bricks? D&D over the whole lot?

    I've already purchased the bath which I bought as the same size as the old one and just fitted the space. So d&d might come up to thick to allow bath to fit. Pics attached for reference...(panoramas from iphone).

    Any help appreciated.

    I’d take anything loose off, leave anything sound, pva it and put a coat of bonding (plaster) on it and rule it off so it’s flat.
    Edit: then skim it before tiling
    Or as you say dot and dab.
    You could always put the bath in first and then dab above/down onto it.

    If you use bonding then you will have to skim it to take the tiles I don't think you can lay tiles on bonding,,,I would knock off all the "boxy" stuff then dub it out with sand and cement mortar.
    Then you can fit your bath and sort out the rest.....

    do you know why that is Roy? I’ve done it before and didn’t realise it was an issue. Not had any issues either (luckily)

    I think it is the texture of the bonding that is the problem as opposed to the smooth texture of plaster...It is more likely to send the tile adhesive off quicker than plaster..
