How can I paint matt over silk paint?

    I have recently moved into a house where every wall has been painted with silk paint. We have tried to paint over it with matt and have ended up with a crackle glaze affect. I have heard that to prevent this we need to sand all the sheen off the walls! Does anyone have an easier solution? Is there anything we can paint onto the walls first to prevent this?

    yes their is. you could paint the walls in soft sheen, which is in between matt and silk but personally i hate it. for a perfect matt finish, give the walls a light sand, mist coat (watered down emulsion 50/50) with white paint and then 2-3 coats of your chosen colour on top. any other prep such as filling will need to be done needless to say

    You should be able to use Matt over silk after doing your usual prep, filling sanding-down etc. A good quality matt paint shouldn't give the effect you've mentioned unless for example the walls have been papered previously and paste residue is still on the walls. Try using sugar soap on them. Making sure you rinse it all off with clean water afterwards.

    matt paint will not cover silk and will cause all sorts of problems without the correct prep. follow my advice and it will be sorted

    Its not peeling or loose but just looks like a crackle glaze effect.

    If the crackle effect wasn't visible before you applied the matt finish. There's a strong possibility that the wall was contaminated with grease or something, if I were you I would sandpaper the affected areas and spot prime with a oil based white undercoat that should stop any further problems.

    Sorry chatchat, forgot to mention use a sanding block to save sore fingers. And to avoid the problem in another room wash down with sugar soap but always work from skirting up. Good luck to you!
