Stair step jig assembly
A stair step jig assembly for smoothing treads on concrete steps includes a jig that is elongated to a predetermined length to extend along a full length of a tread on a concrete step for smoothing the tread before the concrete has cured. A riser adjustment is hingedly coupled to the jig and the riser adjustment unit abuts a concrete form that is positioned against the riser of the step adjacent to the tread upon which the jig is positioned. A leg is hingedly coupled to the jig and the leg slidably engages the riser adjustment such that each of the leg, the riser adjustment and the jig forms a triangle. The leg has engages a top of the riser of the step adjacent to tread upon which the jig is positioned for keeping the jig at a fixed angle on the tread.
