- 1). Scrub the old concrete with stain remover and a power washer. Use a metal scrub brush to rough up the surface so the new layer of concrete will adhere better.
- 2). Repair any pits, potholes and minor cracks. Use a chisel and hammer to widen the bottom and fill any deep cracks with sand until the remaining depth is 1/2 inch from the surface. Spread vinyl patch compound over sides and expanse until it is level with the driveway. Feather out the sides of the patch with a flat trowel.
- 3). Fit 2-by-4-inch form boards against the perimeter of the driveway and connect them end-to-end with screws and a drill. The top of the boards mark the level of the new, raised surface, and should sit 1 inch above the old surface. Wedge stones or shims beneath the boards closest to the home to slope them toward the street for drainage.
- 4). Mix concrete in a concrete mixer using a ratio of three parts sand to one part cement and stir in water until it has a batter-like consistency. If you're uncomfortable mixing it yourself, hire a contractor to do it for you.
- 5). Spray the old surface with a hose to prevent it from absorbing moisture from the new concrete.
- 6). Pour the concrete resurfacing mix over the old surface and push it into corners and sides with a gauge rake. Work a long board across the surface to scrape excess and spread it over low areas. Go over the surface with a squeegee until it is smooth or water seeps to the surface.
- 7). Wait 48 to 72 hours for the new surface to harden. Roll penetrating pure acrylic sealer over the driveway with a roller brush to protect it from weather damage.
