Restoring concrete to its original look can be effectively and efficiently achieved by pressure washing the surface. Over time concrete will absorb oils, mildew will start to grow on the surface, and black grime will get imbedded into the pores. Pressure washing will remove these contaminants by using significant pressure to blast away the dirt and mildew.
When you are using a pressure washer to restore concrete, you must make sure the concrete will not get damaged when pressure washing. Concrete that is flaking or is weak will be etched by the pressure, this will create an unpleasant look. When the concrete is not in good condition to use a high PSI pressure washer, you must use detergents to restore the concrete.
