The device is suitable for both sweeping and applications of surfacing materials such as driveway coater chemicals. The brush block consists of a thermoplastic molded block having an integral squeegee blade. The blade is molded in a predetermined cross-section and interconnected with the block by an integral thermoplastic, thin hinge connector. Pivot stops are provided on the blade so that the blade will pivot a predetermined arc relative to the brush block. Tufts may be mounted in the conventional fashion on an opposite face of the brush block. The brush block further includes a conventional handle to form the push broom coater device of this invention. | |
