Abstract
A mastic applicator includes a guide mechanism mounted to the applicator so that the applicator is maintained in alignment with outside corners during application of mastic. The guide mechanism includes a pair of corner guides which have guide surfaces aligned with the side edges of the outlet from which the mastic flows. The corner guides are spring mounted so that they retract when they are not positioned at a corner, thereby allowing the applicator to be used on both sides of a corner, as well as on flat joints, without adjustment to the applicator. The mechanism also includes a pair of stub guides located on the applicator surface. The stub guides can be slid into position to engage opposite outside corners of a stub wall for effective application of mastic between the outside corners.
