Parking lots take a lot of abuse from all the cars and trucks rolling over them every day. Plus, they are usually in direct sunlight with very little shade, and since they're so wide, rain doesn't roll off of them as quickly as it rolls off a narrow driveway. All these things add up to your parking lot showing wear and tear before you know it. One way to keep your lot looking its best is to apply a sealcoat. A sealcoat keeps it looking fresh and it also adds a layer of protection against the elements. Here's why a sealcoat is a good investment for your parking lot, no matter how large or small it is.
Sealcoating Covers Imperfections In Color
Sealcoating is a thin layer, much like paint. It's dark, so it makes the surface of your parking lot dark again, just like when it was new. The coating also covers oil and dirt stains so the surface of your lot has a uniform color again. The only thing sealcoating doesn't cover up is damage, such as cracks and potholes. Damage will show right through a sealcoat so the cracks and holes must be repaired before sealcoating is applied. Sealcoating isn't done to repair asphalt, it's done to improve its appearance and add a protective coating.
Sealcoating Offers UV Protection
The sealcoat layer protects the asphalt underneath it from direct exposure to the sun. The UV rays from the sun will slowly degrade asphalt over time, so having a protective layer over your parking lot extends its life. Instead of degrading the asphalt, the sun wears away the sealcoating. That's one reason sealcoating must be applied every few years on schedule. Sun exposure, weather conditions, and traffic erode the coating and when it's gone the asphalt is unprotected. By the time the coating is gone, your parking lot has returned to its faded color with stains on the surface.
Sealcoating Protects Your Parking Lot From Water
One important function of sealcoating is to protect your parking lot from rain and water. The coating is waterproof so water beads on top of the asphalt and rolls off into a drainage pond or ditch. Water is bad for an asphalt driveway, especially when there are cracks or holes on the surface. Water sinks down into the base through the cracks if the surface isn't sealed. Eventually, this can cause damage to the base underneath the asphalt, which is costly to repair. Water also helps potholes and cracks get bigger and bigger. Sealing the surface of your parking lot with sealcoating helps prevent water damage, which could save money on repairs.
Working on a parking lot can be disruptive to the businesses that rely on it for customer parking. Your contractor can apply the sealcoating in stages if necessary so your lot can stay partially open during the process. Although it may be inconvenient for a few days, the end result is an attractive lot that's protected from the elements, so the expense and inconvenience are worth it.
