ABSTRACT:
A new tuck pointing apparatus for applying cement to joints between bricks. The inventive device includes a cement reservoir for receiving a quantity of cement. The reservoir has an interior, a closed top end, and an open bottom end that forms a bottom opening into the interior of the reservoir. A mixer portion has open upper and lower ends, an interior, a toothed flywheel that is disposed in the interior of the mixer portion, and a mixing shaft that is coupled to the toothed flywheel. The open upper end of the mixer portion is releasably coupled to the bottom end of the reservoir. The mixing shaft mixes cement in the interior of the mixer portion. A motor portion rotates the toothed flywheel thereby rotating the mixing shaft. A first air tube is in communication with a supply of air pressure and is also in communication with the interior of the mixer portion. The first air tube is for selectively injecting air into the interior of the mixer portion to drive the concrete out of the lower end of the mixer portion.
