I know I'll be shot down in flames for wanting to do this but we are due to move back into our home next week following 6 months in a tiny caravan whilst flood damage was repaired. We have just the weekend between the builders leaving and the laminate flooring being laid/ furniture arriving back. In this time we have to paint all the skirting boards, doors and frames in the lounge/ dining room/ kitchen/ hall/ stairs & landing (argh!!!). We would have prefered to use good paint and leave days in between coats but it's not possible. Can anyone recommend a brilliant white one coat paint in a eggshell finish? I know it will yellow in about a year but we will have more time to paint it again properly then. We need to be able to buy it from B&Q, Wickes or Homebase. Oh, the woodwork we are painting is pre-finished MDF, Do we need undercoat?
