Never wrap a full width wallcovering round an inside corner. Always do it in two pieces.
First measure the distance from the edge of the last piece you hung to the corner. Do this at several points between the ceiling and skirting to find the maximum distance. (see fig. 12).
Cut a length of wallcovering so that it is about 25mm (1") wider than this measurement, paste it and hang with the extra 25mm overlapping round the corner on to the next wall (see fig. 13).
Where corners are not accurately plastered, you must be more generous with the overlap. Take the remainder of the length and paste it. Measure it and mark a vertical guide line on the next wall, a little more than its width out from the corner.
Now take this second length and hang it alongside the vertical line and perfectly parallel to it (see fig. 14)...
...brushing back into the corner and overlapping the 25mm which has already been carried round (see fig. 15).
Match the pattern as well as you can, although a slight mismatch in the corner is normally not too obvious.
Outside corners Follow the same technique, although you should allow a wrap-round of at least 50mm (2").
Overlapping thicker wallcoverings like blown vinyl can be difficult to stick down. In this case, slice through the two thicknesses after overlapping and remove the surplus pieces from underneath, so giving you a perfect butt joint. When slicing through, use a good straightedge and a very sharp knife, cutting at a low angle - and take great care.
Ordinary flat vinyls or wallcoverings with a similar shiny surface will need the use of a special adhesive (e.g. Albany Border & Overlap Adhesive).
