    Wondered if anyone could give me any advice.
    I had my walls plastered a couple of months ago, and once dry, gave them a mistcoat of emulsion which was fine. however, once i applied the basecoat and topcoat of emulsion, i noticed small blotches/stains around where the angle bead was placed. the blotches are lighter and shinier than the rest of the emulsion. i was told that this was something to do with the galvanised nails used.
    i decided to use an oil-based primer (which was actually made for wood!)over the blotches, which seemed to cover them, but now i'm having trouble concealing the primer with the emulsion.

    I have been told a coat of PVA may do the trick, and that plenty of emulsion will eventually cover it, but i've also been told i may have to sand back to plaster and start again.
    not quite sure what to do!!

    Any Suggestions welcome thanks

    Marioe,
    There is a similar question to yours in the Plastering and Rendering section.
    Title of the post: "Corner Bead showing through Paint". This will give you your answer. Only posted a few days ago.
