I’m in the process of redecorating our living room. I stripped off the wallpaper and found a layer of white paint beneath that wad flaking off in many places, so I decided to strip this all off as well. I want to paint the walls so I patched and sanded them where needed and then washed down with soapy water. Then I applied a mist coat of Wickes Matt white emulsion diluted by 1/3. So far so good, but when the mist coat was dry I found that, running my hand over it, it comes away in a chalky powder. Never having mist coated a wall before, I wasn’t sure if this was normal, so today I tried test painting a couple of small areas with undiluted emulsion. When dry the emulsion comes away in a chalky powder too. I tried wiping the painted area with a damp cloth and it wipes right off!
Can anyone tell me what I have done wrong? And what I need to do to rectify matters? I’d be very grateful for any help or advice.
