Redecorating and am about to put up plaster coving (127mm)... When I done it before I've been fairly successful at hiding the joints between lengths just by butt joining the lengths, aligning as best as I can followed by careful filling of the joint afterwards.
However, one mate says he had a tip from a pro to cut a matching wedge shape off both ends (say 45 degrees- see rough diagram of 2 lengths below) ______ _______ ______/ /_______
and butt these together... claims it makes a more invisible joint? Any one tried it? Any comments? Andy
