To accurately and beautifully perform pectination spacing patterning by downwardly providing approximately triangular plate-like bodies in both side end portions of a plate-like main body and angularly moving a sawtooth-shaped application blade in a pectination spacing patterning applicator for patterning lateral pectination spacing onto a design paint material painting a wall surface of a building.

In a pectination spacing patterning applicator, a sawtooth-shaped application blade 11 is formed in one end of a plate-like main body 10, and a handle 12 is provided on an upper face of another end of the main body 10. The pectination spacing patterning applicator is configured by downwardly providing approximately triangular plate-like bodies 13 in both side end portions of the main body 10 so as to be upwardly inclined from the sawtooth-shaped application blade 11 to the other end where the handle 12 is provided.
