I'm quite capable of skimming small area's ie bathroom ceilings, patches around sockets etc etc. A friend has now asked me to save him some money and skim his small bedroom. One wall is boarded and the others are just old plaster that needs a new life. Any tips/tricks to getting a good finish? I take it I should start with the ceiling and then the walls, was going to pva the lot first and use board finish on the board and multi finish everywhere else! All useful advise welcome.
