<p>The invention concerns a building accessory (10) for plastering and optionally for jointing. The accessory includes a radiussed angle-profile concave working surface (24) for plastering and shaping an outer corner defined at an intersection between two walls of a building structure and a radiussed angle-profile convex working surface (32) for plastering and shaping an inner corner defined at an intersection between two walls. The accessory further includes a mounting arrangement (16) located between the respective radii of the concave working surface and the convex working surface and a griping member (18) connected to the mounting arrangement. The concave and convex working surfaces are movable between two operative positions in which it is lockable for use on concave and convex working surface respectively.</p> |
