Before you get started you will want to remove any loose concrete or damaged concrete from the stairs.
Clean the concrete stairs with a wire brush and use a broom to clean up any dust or loose debris from the surrounding area.
Fill fine or small cracks with a vinyl concrete patching compound. The easiest and most efficient way to apply this compound is to use a putty knife.
To repair the surface or edges of stairs a quick setting cement should be used. First you will want to dampen the area with water without oversaturating it. Mix a quick setting cement as directed by the manufacturer and trowel into the damaged area. If needed as a guide, use a single piece of wood as a form for applying concrete to the top of stairs or two pieces of wood forms to repair a corner. Once this is complete you are then ready to smooth the mixture with a trowel to match the other stairs and let set.
