Abstract: An improved corner junction paint roller comprised of a paint-roller corner-painting assembly that attaches to the end of a conventional paint roller. The attachment provides either a bristle end resembling a brush or a flat perpendicular end having a surface identical to the surface of the paint roller. By using the invention at the corner of one wall the adjacent corner wall is painted simultaneously. The improvement also includes a second embodiment that consists of replacing the standard paint roller with an extended version of the paint roller. The extended roller functions in a similar manner as described for the paint roller painting assembly. The extended roller is available with either a bristle end or a flat painting surface covered with a soft painting conducive material.
