Asphalt paving is a wonderful choice for the construction of parking lots, but it does require care and maintenance if it is to reach its full lifespan. With that in mind, you might be wondering if having your asphalt parking lot seal coated is a good idea. Is it really necessary and, if so, why?
Why Seal Coating is a Good Idea for Asphalt
According to the experts at Parking Lot Pros, asphalt seal coating is a good idea as otherwise it can become susceptible to cracks and damage, both of which will reduce its lifespan.
Damage to asphalt paving can be expensive to rectify,but it can also be entirely preventable. With regular maintenance and seal coating on the asphalt, parking lots are protected from the elements. Over the course of an asphalt parking lot’s lifetime, seal coating can save the owner quite a bit of money in costly repair work.
It is not just water and other chemicals that can affect unsealed asphalt though. UV light can deteriorate the binder in the asphalt mixture, which then causes it to lose oil and become very hard. You might think that this is a good thing, but without these oilsthe asphalt becomes dry and brittle,which is when cracks start to form. These cracks need to be repaired as soon as possible to prevent them from worsening. Repairing cracks in asphalt is not easy, and it can be costly as well. It is much better to seal coat the asphalt from the outset to avoid these issues.
In addition to its protective qualities, asphalt seal coating is also aesthetically pleasing and will make your parking lot much more attractive. The dark coating on the asphalt looks glossy and well maintained. When your parking lot looks well maintained, it creates a particularly good impression of your business. New and existing customers will be assured of your dedication to quality when they see the care that you take of your business’s exterior.
How is Seal Coating Applied
It is important to be aware that seal coating should not be applied within the first six months of the asphalt being laid. Indeed, some companies recommend a wait of between 12 and 18 months. The reason for this wait is to allow the oils in the asphalt to rise to the surface.
Before the seal coat is applied, the asphalt will be cleanedand any required patching work will be carried out. The seal coat is then poured over the surface of the asphalt and allowed to dry. The type of seal coat applied will usually depend on budget and expected usage of the surface. Coal tar sealers are typically chosen by those who want to keep costs down. This type of sealer is less expensive than asphalt emulsion sealers, but it does not provide as much protection, particularly from chemical spills.
How Much Does Seal Coating Cost?
The cost of sealcoating an asphalt parking lot will depend on a number of factors, including the size of the parking lot and the type of sealer that is being used. For a more professional finish, it is best to have the seal coat applied by a reputable company.
It is important to bear in mind that seal coating must be reapplied every three to five years to ensure the maximum protection for your parking lot.
In conclusion, asphalt seal coating is highly recommended. Although it may be seen as an added expense, it will protect the parking lot and reduce or eliminate the need for costly repair work.
