How Often Should I Sealcoat My Parking Lot?
We are often asked “How often should I sealcoat my parking lot”? Our recommendation is every 24-36 months. Weather can play a role in how often you should sealcoat, in addition to the traffic on the lot. If your lot is showing signs of cracking, wear and tear and fading, it is a good idea to have your parking lot assessed by a paving professional.
Benefits of Sealcoating
- Beautification When covered with a dark black sealant, pavement looks and wears like new. Parking lot sealcoating helps to project a positive image of the company, facility, or residential complex.
- Slower Oxidation Sealcoating fills surface voids, which reduces exposure to oxygen and UV rays and reduces the depth to which oil or gas can penetrate the pavement.
- Slower Water penetration Sealcoating acts as a waterproofing agent, minimizing the rate at which water enters pavement. Without it, water can permeate more freely resulting in freeze/thaw expansion and contraction of the pavement.
- Resistance to Oil and Gas Spills Gasoline dripping from a topped-off fuel tank during hot weather can soften and break down unsealed asphalt pavements. Coal tars used in sealcoat are impervious to gas and oil spills.
- Easier to Clean and Maintain Sealcoats fill surface voids while coating the pavement surface. The resulting smooth and even texture makes the surface easier to maintain year-round. For example, snow is easier to remove from a smooth surface, and sweeping is far more effective on a smooth surface.
- Increases Pavement Pliability Sealcoat brings a dark black color to the pavement. The blacker it is, the more heat a pavement draws from the sun. And, the hotter it gets, the more pliable it becomes, which helps it to withstand traffic without cracking.
- Protects Asphalt from Pressure Washing Restaurant parking lots often extend to areas near dumpsters, where food-processing machines are pressure washed. Food waste near the dumpsters may also need to be washed away if it can’t be swept away. Sealcoating protects asphalt cement from the high-volume water pressure and detergents used in pressure washing.
- Cost Effective The price of asphalt will always be affected by crude oil prices, which fluctuate when supplies vary. Sealcoating preserves asphalt for pennies per square foot.
