One tip for installing concrete stairs is to use an online stair calculator to determine the necessary dimensions for the stair base and to create a diagram. Use scrap or low-grade lumber for the stair base, and mix the wet concrete by hand to cut down on overall cost. Alternatively, use a cement mixer to lessen the labor of the project.
Once the stair base is complete and the cement mixed according to the manufacturer's directions, pour the cement by filling one step at a time, starting with the bottom step. Make sure the concrete is level and avoid air bubbles by using a rod or a spade.
Use a screed board or a wooden plank to ensure a level surface. Pass it over the level edge of the stair base frame as a guide. Gently rock the screed board back and forth to remove excess concrete. Achieve a finer and less bubbly finish by using a steel trowel.
It is important to allow concrete steps to cure properly. Curing is a week-long process in which the concrete must be kept damp. First, spray the concrete with a curing compound, and then wrap it tightly in either plastic or burlap.
