I'm about to replace a small ceiling (7'4" X 7') with tapered edge plasterboard. I am not skilled enough to do a good job with skimming it so intend to just fill in the joints and paint it. Hence the tapered edges.
It occurred to me that I may have some instances where I will have a square edge butting up against a tapered edge because of the need to cut the boards. I'm sure this can be done but how will it affect the final finish? Surely there will there be humps where this occurs?
