There are many benefits to sealcoating the asphalt to your driveway or parking lot. Think of sealcoating more of as preventative maintenance for your driveway or parking lot. It’s very similar to how you paint your home to keep the weather from deteriorating the wood.
Sealcoating Benefits: Prevention, Preservation, and Protection
Sealcoating the asphalt seals the small cracks that can get larger and prevents water from seeping down to the base. The dark black color of newly applied seal coat improves the appearance of new and old asphalt. Hence, this makes your driveway or parking lot look near brand new.
New sealcoating can preserve the resilience of asphalt surfaces and help hide small cracks, patches and rough spots. It can also make traffic lines on parking lots more visible. When applied correctly, sealcoating makes your asphalt driveway look cleaner. Rain washes dirt and debris easily away from the smooth, non-porous surface.
Another benefit of sealcoating is that it helps protect the asphalt from the sun as well as the harmful effects of chemical spills such as oil and gasoline. These are both all too common on a driveway or parking lot. Asphalt sealcoating fills surface voids. Therefore, it reduces exposure to oxygen and UV rays and reduces the depth to which oil or gas can penetrate the asphalt.
Sealcoating acts as a waterproofing agent, minimizing the rate water enters the asphalt which prevents the seepage of water and moisture from rain and snow. As a result, it prevents damage from freeze thaw cycles. This is a common reason your driveway or parking lot begins forming cracks or even worse, alligator cracks. Sealcoating also provides an attractive black surface that is ideal for painting lines and other markers on parking lots.
Sealcoat is a dark, black colored material and when applied to asphalt, it helps attract more heat from the sun. The hotter the sealcoating on the asphalt gets, the more pliable it becomes. This aids in withstanding traffic without cracking. The price of asphalt will always be affected by crude oil prices which fluctuate when supplies vary. Consequently, coating preserves asphalt for pennies per square foot, verses costly asphalt repairs.
Sealcoating leaves a smooth, clean surface ideal for sweeping which lowers cleaning costs and gives your entrance and/or driveway a fresh, new look much like painting your home or business. It fills surface voids which reduces exposure to oxygen and UV rays and reduces the depth to which oil or gas can penetrate the asphalt. It acts as a waterproofing agent, minimizing the rate that water enters the asphalt of your driveway or parking lot.
Sealcoating costs pennies per square foot compared to the dollars needed to repair or replace damaged asphalt. The intrusion of moisture into asphalt accelerates its deterioration and is strongly related to asphalt distress. Coating seals the asphalt pavement, preventing the oxidation and erosion of the top layer and replaces fine particles lost from the asphalt surface due to oxidation on older pavements. It also resists gas, diesel fuel, oil, salt and chemical penetration which will break down the bond between the aggregate and the liquid asphalt.
