Cleaning the floor

If the concrete floor has pre-existing oil stains, you’ll need to remove them first because they will inhibit the penetration of densifiers, dyes, and stains, resulting in unwanted color variations. Degreasers and detergents are usually sufficient for removing lightly soiled areas. For heavier oil stains, try using a poultice powder-a blend of dry absorbent clay that’s effective at extracting stubborn oil and dirt stains from concrete. For light oil stains, you can also try pouring mineral spirits onto the stain and then absorbing it with kitty litter.

On some projects, you may need to remove vinyl tile or asphaltic adhesive membranes from the concrete surface prior to grinding. If vinyl tile needs to be removed from a large area, the most efficient method is to use a ride-on machine specifically designed to scrape the tile off the surface. These machines are useful for removing a wide range of materials from concrete surfaces including thick coatings (such as epoxies or urethanes), adhesives, thin-set mortars and floor coverings.

If mastic or adhesive must be removed from the floor, the quickest method is to grind the material off, versus using a chemical stripping agent. Most manufacturers of grinding equipment and diamond tooling will have accessories designed specifically for this purpose.
