Mechanically remove any surface laitance and patch or fix cracks and damaged areas. Completely remove all membrane forming curing compounds, sealers, coatings, paint, oil, grease, dirt, dust and other containments. It is recommended to thoroughly clean the surface with a black scrubbing pad (light abrasion) and a neutral pH detergent. Etching of the surface with an acidic solution is NOT recommended, because it requires a thorough rinsing process using a neutral pH cleaner to effectively neutralize the entire surface (if not properly neutralized, the pH condition may cause whiting). For best results, clean the surface by sanding the floor with a 60-100 grit sanding screen or diamond abrasive pad. Remove dust and residue with a riding or walk-behind “scrubber” utilizing water or broom, then water rinse and squeegee surface dry.
