Im intending to paint my property internally.One area Im a little unsure of is how I can best achieve a good finish between the wall and ceiling, as they are to be different colours.Ive seen the paint pads but I can just imagine that they wont be that easy to use an judder along and end up causing a wonking merge line.What I intend to do is add masking tape all the way along the merge line.Is this likely to remove the paint after I peel it off.Other method would be to get one of those plastic guides, but Im sure they wont alwys stop all the apint and paint wil run slightly of the edge that is pressed against the merge line.
