I have just covered up some old wooden cladding, to a bathroom ceiling in a chalet bungalow style 1930's house, with plasterboard and need to skim it. There are two triangular shaped areas which are, in effect, the inside of a roof valley. Any tips on tools to use and techniques would be gratefully received. There are several corners that I can't get anywhere near with a rectangular shaped trowel and I'm thinking of using a pointing trowel!
Cheers.
