You can’t just fix things with more cement; instead, you’ll need a specific repair mix. Pay close attention to the cement repair mix you buy. For large cracks or chipped edges, mortar mixes are a good choice. If your cracks are 1/8-inch or narrower, you’re better off with latex or epoxy mixes.
Before you can seal the crack, you will need to widen the space below the surface. This process is known as “embedding” and helps the concrete repair mix adhere better. You will do this with your chisel. Insert the chisel at an angle into the crack, then use the hammer to tap gently.
