Build a wooden frame for broken corners. Cut boards to fit the sides and front of the step that needs repair. Nail them together to make a frame to hold the concrete. Cut pieces of bracing that will run at a diagonal from the step to the ground. For a secure brace, nail a perpendicular piece of wood where the brace anchors against the frame and again where it meets the ground.

Mix concrete according to manufacturer's directions and fill the corner of the frame. Use a trowel to smooth and level the patch. Leave the boards in place until the patch is dry.

Repair cracks in concrete slabs with foam backer rod, a type of patching rope sold in lumberyards. Cut the length needed and push it into the crack. It will expand and create a surface. Use a stiff-bristled brush to apply vinyl concrete polymer. It will flow around the backer rod and fill the crack.

Patch chipped and cracked concrete with a vinyl concrete polymer patch. Clean the area thoroughly and sweep away dust that would embed in the polymer. Use a stiff brush to paint this thin coating that instantly fills chips and small cracks.
