    Hi all,

    I live in a one bedroom maisonette, and all the walls are what I refer to as "drywalls", I'm not sure if that's the right term. But they are like 2 boards of plaster with a gap in between them, and the plaster is covered by some sort of paper.

    Anyway, my big utility cupboard the old paint has peeled off in big sheets (paint was there when I moved in, and clearly they didn't undercoat/mist it).
    My issue is thus - I've only painted one section so far with this mist coat, but is there a chance you can mix the paint with too much water? I made mine REALLY watery because I never want it to peel off again, but after painting I started thinking too much water might have killed the stickiness property of the paint?

    Is there a test I can do to ensure the paint has adhered to this paper surface?
    I've rubbed my dry hand across it and doesn't seem to be powdering off.

    I'm worried I will put normal coats on it now and then have to do the whole thing all over again. (I'm only painting it in white mat emulsion by the way).


    Also one more - Mist coats are only needed for bare walls right?
    If a wall is already painted in matt emulsion, I can whack a different colour straight on the top without any watering down at all?


    Thankyouuu.

    Making it too watery won't hurt, it may simply be ineffectual. Just go over it again with another mist coat, this time about 30% water.

    Mist coats are needed for anything made of bare plaster or other water-sucking material!

    Yes, if the old paint seems to be sticking OK.
