Abstract
An applicator tool for applying cementitious materials such as joint compound to corners. The tool has a handle and a head which is curved. The handle and head are integrally formed preferably from plastic. A flexible elastomeric blade projects from the forward edge of the head to smooth the compound. A one-piece molded corner cap in a general trihedral shape is provided and when using the tool results in a smooth, uniform finished corner.

An applicator for applying cementitious compound from an elongate narrow trough to corners and edges and for smoothing same, said applicator comprising:
- (a) a longitudinal body having a handle with a rear end and a forward end and having an integrally formed head secured at the forward end of said handle, said head having a forward edge, said handle and head being transversely curved, each having opposite concave and convex surfaces, said head having a transverse dimension greater than the transverse dimension of the said handle;
- (b) an elastomeric blade affixed to said concave surface of said head and having a working edge extending forwardly of the forward edge of said head;
- and the convex surfaces of said handle and head being disposed at an obtuse angle relative to one another whereby said applicator is reversible to apply compound scooped longitudinally from said trough to both interior and exterior corner surfaces.
