Abstract
A covering over the 90 degree corner of gypsum or plasterboards which rounds the corner to a small radius and thus provides a desirable commercial appearance thereto, which uses heat shrinkable tape to fuse the covering in place and also, as a result of the shrinkage, cause the removal of any wrinkles therein as might otherwise undermine the objective of the covering.
