New coatings only perform as well as the surface beneath them.
Oil-saturated asphalt, organic dirt, and flaking old paint interfere with adhesion. Painting over a failing layer simply transfers that failure to the new coating. The same is true for “blacking out” obsolete parking lines: as the cover coat weathers, ghost lines return and confuse drivers.
Professional surface preparation removes contamination and outdated markings so new sealers, striping, and curb coatings start with the cleanest practical base.
Preparation methods
Commercial hot-water power washing
High-temperature cleaning and rotary surface cleaners lift grease from drive-thrus, dumpster pads, parking stalls, and concrete areas before coating.
Mechanical scarifying
Rotary equipment with carbide cutters removes thick paint and thermoplastic buildup while the operator controls cutting depth around the underlying surface.
Abrasive and high-pressure blasting
Abrasive media is especially effective on concrete curb paint buildup. High-pressure water systems can be used where the surface calls for a lower-dust or less mechanically aggressive approach.
