The apparatus and method comprise a concrete float with a vibratory additive broadcaster assembly attached therewith. The broadcaster assembly is suspended above the plane of the finishing tool with a vibratory source attached. The broadcaster assembly is filled with an additive and the apparatus is placed on a wet, concrete surface which is to be treated and finished, by a user. Actuation of a power switch by the user activates the vibratory source resulting in the substantial broadcast of additive on to the concrete surface at the desired location(s) on the slab as determined by the user. The additive is then integrated into the concrete by passage of the float over the treated concrete surface.
