Definition
Seal coating is the application of a protective layer over asphalt surfaces. This liquid mixture, typically composed of bituminous-based products or acrylics combined with water, silica sand, polymer additives, and other fillers, acts as a formidable shield against asphalt’s primary enemies.
Unrivaled Protection
UV Resistance
Seal coating functions like “sunscreen for your pavement,” blocking harmful UV rays that cause oxidation and make asphalt brittle. This helps maintain the asphalt’s flexibility and structural integrity.
Waterproofing
By filling surface voids, seal coating significantly reduces the pavement’s porosity, minimizing water infiltration into the base layers. This proactive measure is crucial in mitigating freeze-thaw damage and preventing potholes.
Chemical Spill Resistance
The non-porous barrier created by seal coating resists harmful spills like oil, gasoline, and antifreeze, preventing them from penetrating and deteriorating the asphalt. Cleanup also becomes easier.
Oxidation and Erosion Prevention
Seal coating prevents the oxidation and erosion of the top layer, replenishing the fine particles and oils lost from older pavements. This preservation extends the pavement’s useful life, with routine sealing every 2-3 years potentially helping asphalt last up to 30 years.
