Safe & Looking Good
Asphalt is an affordable, durable material, which is why it’s so popular for use in roads, parking lots, and driveways. However, once it’s applied, exposure to UV rays, water, oil, and road salt can cause the asphalt to dry out, fade, crack, and crumble over time.
A sealcoat is a protective coating made from specially formulated oils and paving material. When applied, this coating soaks into the asphalt, restoring appearance, replenishing the oils and elements that have deteriorated over time, and filling in small gaps for a smoother appearance.
The sealcoat also lays on top of the asphalt, forming a protective barrier to prevent future damage caused by sun, water, oil, and salt.
Key Features of Asphalt
Sealcoating Breathes New Life into Faded Asphalt. When asphalt is first laid, it’s a deep black color that looks fresh and new. Over time, the sun and elements will fade the pavement, making it look washed out, gray or white, and dingy. Sealcoating restores that rich, glossy black color to the pavement, returning it to a fresh, new appearance which can improve the look of your property and even increase its value.
Prevents Pavement from Becoming Brittle.
Pavement is made up of a blend of sand and gravel aggregate mixed with a petroleum-based binder that makes it flexible and pliable. As motor oil and gasoline leak on the pavement, not only will it stain, it reacts with the petroleum binder and causes rapid deterioration. On top of that, water and UV rays dry out the asphalt. Soon, the asphalt that was once flexible enough to handle temperature fluctuations and the pressure of traffic becomes brittle and prone to cracking and crumbling under pressure.
Applying a sealcoat blocks the damaging, oxidizing substances and keeps the binder pliant and flexible, allowing it to stay in good condition for a longer period.
Sealcoating Prevents Potholes. Once the pavement becomes compromised due to oxidization and oil exposure, deterioration begins quickly. Small cracks form in the brittle pavement, and, if left untreated and unrepaired, they will quickly turn into unsightly, dangerous potholes. Because sealcoating prevents oxidation and cracks, potholes are much less likely to form, keeping your roads safe and attractive for a longer period of time.
Sealcoating is Cost-Effective. Having fresh asphalt laid down is expensive, costing on average between $1.50 and $2.00 a square foot, not including any line striping or curb installation. That’s just installing asphalt.
On the other hand, sealcoating costs between $0.15 and $0.25 per square foot. By investing in a sealcoating every few years, you’re minimizing the need for expensive repairs and extending the life of your pavement.
Don't sealcoat Fresh Asphalt
Fresh asphalt should cure generally for three to six months. After curing, sealcoating can be successfully applied.
Sealing Pavement Needs to Be Maintained
Once you have your asphalt sealed, it will need to be maintained. While it’s not a frequent task, a sealcoat lasts around two to three years, so you will want to take that into account when you do a maintenance budget for your property.
Your Asphalt Needs to Be in Good Condition Before Sealing
While sealcoating can be applied to dry, faded asphalt or a surface with minimal cracking, it won’t restore or repair cracked or crumbled pavement. Make sure any repairs are completed; cracks filled, potholes patched, before sealing.
