Removing Staining, parking line markings and traffic lines for re routing or construction is often the first alteration to an asphalt surface.
The cleaning process you choose to remove these contaminants from asphalt driveways, patios, parking structures, roadways, or runways must be carefully considered before arriving at a decision to proceed. The process may range from ineffective, to harsh and damaging causing disfigurement.
Traditional Cleaning Methods:
Traditional Cleaning methods can usually be broken down into 3 categories: Water, Chemical, and Mechanical
Water: A high-pressure wash can destroy the asphalt and tends to not be very effective.
Chemical: chemicals and solvents dissolve the asphalt even in a diluted form. Some chemicals can change the color of the asphalt itself as well as leave a hazy residue despite a heavy rinse.
Mechanical Cleaning: hand tools, grinders, sanding discs, wire brushes, etc. all abrade the contaminants off the surface with damaging results.
