How to Clad Concrete Steps in Stone

Use the tape to center the first tread, and set it in place, flamed edge outward. Check for an equal overhang on the sides and for level side to side. You want a very slight slope toward the front, to shed water, but no more than 1/16 inch per foot. Working out from the center, strike the tread with a rubber mallet to set the stone. Set the remaining treads, maintaining a uniform front overhang and height above the previous tread. Check your local codes for stair heights, and to keep people from tripping, make sure the height of each riser is within 3/8 inch of the others.
