Hi. I have come across problems painting matt over silk emulsion. I am trying to cover cream walls with a rather less creamy shade so thought two coats should cover it easily. But the finish is terrible -- the bits done with a roller look all patchy, especially when the sun shines on it, and the same with the bits done by brush, like the coving, it all looks very uneven. I have now put four coats on it but no improvement. I have looked on various sites and realise now that it was a bad idea to paint matt over silk, but the problems others had are different from mine - like a crackling effect, which I, fortunately, have not experienced. I am using good quality Dulux emulsion. Has anyone had similar problems? What is the best opiton at this stage? I have not got time to strip down all the walls to the plaster and don't like a silk finish. Is there anything else I can do to solve the problem?
