Old concrete must be rigorously cleaned to ensure proper adhesion of Concrete Resurfacer to the old surface. Follow these easy steps to prepare the surface:
Manual Cleaning of Debris from Surface
• Wash, sweep, scrape, chip or grind the surface to remove loose concrete and foreign materials such as paint, greasy residue, algae, mildew or other materials which may be stuck to the old surface
• Clean the surface using a 3500 psi (24 MPa) pressure washer
NOTE: This step is essential in order to ensure a proper
bond is achieved.
• Follow pressure washer manufacturer’s instructions as to safe operation and effective use
• Hold the wand a few inches from the surface to strip away all foreign and loose materials
Penetrated oil or grease stains can be removed by acid washing, detergent washing and bleaching, following manufacturer’s instructions. Acid washing can damage the existing concrete if not performed properly. Be sure to rinse thoroughly with water to remove traces of cleaning solutions. Incomplete rinsing will interfere with performance of the Concrete Resurfacer.
