ABSTRACT:
A method for transferring generally radial patterns to topping compound applied to a surface using a stipple brush. The stipple brush has a two-sided base plate having a first side moveable into substantially parallel adjacency with the surface to be stippled, an oppositely disposed second side, and an outer edge. The first side of the base plate has disposed therein a predetermined pattern of brush receptacles which are all acutely angled at substantially the same angle with respect to a central axis extending perpendicularly through the base plate, and which radiate outwardly therefrom toward the outer edge of the base plate. A plurality of brush elements having predetermined lengthwise extents are disposed in the brush receptacles at orientations defining substantially the same acute angle with respect to the central axis of the base plate as the brush receptacles. The brush elements extend radially outwardly toward the outer edge of the base plate to expose their lengthwise extents so that substantial portions thereof contact the surface upon movement of the base plate first side into substantially parallel adjacency with the surface. Upon their withdrawal from contact with the surface, the lengthwise extents of the brush elements transfer a generally radial, consistently repeatable predetermined pattern to the stipplable topping compound.
