Sealing your asphalt driveway or parking lot will prevent it from deteriorating and sustaining more damage in the future. The right time of day for sealing will depend on the climate, traffic and location. High-quality coal-tar-based sealers will resist wind and dust damage. The best time to seal your asphalt depends on your budget and the level of traffic it receives. You should reapply seal coat every three to five years depending on the climate and traffic.
Sealcoating prolongs the life of your asphalt driveway or parking lot
Regularly applying sealcoating to your asphalt driveway or parking lot can extend its life by as much as 20 years. However, sealcoating is an important maintenance task that must be completed within 12-18 months of asphalt installation. Furthermore, the process should be repeated every two to three years. If not, it could damage the asphalt. Regular sealing should be paired with regular crack repair and inspections.
Besides protecting the surface, sealcoating also prevents cracks and potholes from forming. This prevents further breakdown of the asphalt surface and may ultimately require a full replacement. Regular sealing also saves you money since replacing asphalt is more expensive than regular maintenance. Sealcoating is also beneficial for parking lots and driveways as it prevents weeds from poking through cracks and extends the life of the pavement.
Cost of sealcoating
One of the most important things you should consider when laying an asphalt pavement is the cost of sealcoating. Although asphalt is a durable material, exposure to water, oil, and UV rays can weaken the concrete, making it prone to cracking. Sealcoat protects asphalt from damage by replenishing broken oils and filling in small gaps between the aggregate. It also adds aesthetic appeal to a property.
Before you apply the sealcoat, the surface needs to be clean. Otherwise, the sealant will not bond properly to the surface, resulting in flakes. To remove these contaminants, you can use a gas blower, degreaser, scrub brush, or water hose. If the surface is greasy, you may want to hire a professional to do the job. A professional can power wash the surface to ensure that it is sufficiently clean to accept the sealant. This process typically costs anywhere from $1.50 to $4 per square foot.
Time of day to apply sealcoat
There is no one correct time to apply a sealcoat to your driveway after asphalt is laid. You should do it when the temperature is above 40 degrees Fahrenheit and the air is dry. However, applying sealant in direct sunlight will dry the sealant faster than in shaded areas. As a result, you should avoid applying the sealant during the day if possible. Alternatively, you can choose to apply it in the early morning hours or at night when there is less sunlight.
Summer is the best time to apply sealcoat after asphalt is laid, as the temperature is warm enough to speed the curing process. Typically, you won’t need to wait more than 24 hours for the sealant to cure. However, this won’t be ideal for everyone, as most people don’t want to wait for more than a day to use their driveway. Plus, warmer temperatures mean less humidity, which is perfect for applying a sealcoat.
Deterioration of asphalt pavement
There are many reasons why asphalt pavement deteriorates after it is laid. Some deterioration occurs immediately, but more noticeable deterioration begins about three to five years after installation. Cracks develop and the asphalt surface becomes gray, which can eventually spread and cause the base to deteriorate. The only way to stop this damage is to take action before it gets too far. Here are a few examples of what can happen to your pavement.
Alligator cracking: This type of deterioration is often caused by excessive load and poor drainage. Fatigue cracking causes a pattern similar to the skin of an alligator. Cracks in this type of pavement are difficult to repair and will continue to deteriorate without immediate action. In the short term, crack fillers and sealcoating are usually sufficient to contain the cracks and prevent further damage.
