Abstract
A paintbrush having an elongated handle has a brush head containing a continuum of bristles configured from a multiplicity of primary short bristles and secondary longer bristles with split and smaller diameter distal extremities. The effect of the primary shorter bristles is to release coating liquid onto the longer bristles during bending. The effect of the distal end of the secondary longer bristles is to function as smoothing of the discharged coating in lieu of physical stroking requiring human muscular strain.
Claims
exact text as granted — not AI-modified1 . “A coating” brush “with” bristles, presented against an architectural surface simultaneously at lengths, maintained by the embodiment, such that finer hairs protrude longer than stiffer hairs.
