When u see a yellow stain around the area a its a dampstain u have when you see a white power dust on your wall when you rub it this is the salts coming out ot the plaster cause by damp also to know when there us a black mould this is because of condensation and not enought air circulation in the room. how to help prevent thus leave a window open on first catch if possible or open windows more often as you will find it on windo walls or door areas

When applying paint on walls using matt emulsion has less chance of showing up showing roller marks and when using soft sheen it will highlight all your bad walls including roller marks which no one can help how they dry out. best thing to do is cut in a wall first and roll it before it drys leaving less chance of different marks getting as closed to the end of the wall were you have cut in

You should remove it after second coat but don't leave it on as it will be harder to remove and the paint can get in behind the paper and can tear the paint on the wall when pulling it the paper off

I wouldn't recommend it as it won't stick as good and if the paper has a texture on it or bad over laps on it. the chances are they will all show and you will be back to square one so i recommend to strip it first for best result

2.5 ltrs of paint is more than enough to paint your doors how ever it will need an undercoat with plenty to spare
