    Default Top coat in tiled area

    My bathroom has newly installed wet area plasterboard. Unfortunately some of the joints where tiles will go have been flushed with top coat.
    Can (should) I seal or waterproof these areas before tiling?

    Sand it off, will just fall away with little effort.

    No doubt about it.

    I would coat the whole area.

    Wet area Plasterboard has a WR rating but it is only a thin layer on paper to protect the plaster inside.

    I would strip any plastered joints and seal them with a flexible sealant like Sikaflex 11FC, also seal all screws with the same sealant as well as the taps / mixer and the shower outlet spigot.

    A single pin hole can result in starting all over again, so fully tank the shower walls as well.

    Good luck and fair winds.

    Common to have the sheet joins base coated under tiling/waterproofing. As phil said, I'd probably sand off the top coat, which is very easy. Prime walls and joins/ floor ? with a primer called up by the water proofing membrane being used.

    Have now sanded off the top coat.
    Thanks all for your responses, I didn't even think of trying to remove it.
