“Surprisingly, many home owners, property owners, and maintenance workers know not much about the important aspect of sealcoating. Sealcoating will provide a layer of protection blocking out the elements of water and oils and U.V. damage. In addition, when placed on manufacturers’ specifications, sealcoating provides a slip resistant surface with a deep black finish that beautifies the parking lot or driveway too. Oxidation and water penetration are the main reasons for asphalt pavement failure.”
Sealcoating is usually forgotten by many people because they’re unfamiliar with it or they just have a bit knowledge of it.
Sealcoating is a general expression used to describe putting on a top coating, or protectant coating of material over a current asphalt pavement. Asphalt pavement comprises of rock, sand, gravel, and a binding agent to keep it completely. The binding agent is a by-product of the distillation process of certain types of crude oil. As asphalt ages and this by-product breaks down, unfortunately it will lose its ability to bind, or hold together. Maintaining this binder is the vital thing in pavement maintenance. As one would expect, without them, the asphalt are going to break down. The most typical causes of binder degradation are rain, ultraviolet rays from the sun, and chemicals just like antifreeze and car oil.
Normal daily use in addition to harsh conditions may at some point loosen the top layer of asphalt ultimately causing erosion. This tends to result in moisture penetrating the asphalt, slowly breaking up the surface with freeze-thaw cycles.
To lessen this harmful process from damaging pavement from rain, a lot of people opt to use a protective layer, or a seal coat, over the pavement to give the life of the parking lot or driveway and also to prevent degradation. Additionally, when sealcoating products are put on manufacturers’ specifications, they provide a slip resistant surface with a deep satin black finish that beautifies the parking lot or driveway.
With respect to the intent behind the paved surface, some other sealcoating material can be utilized. Property owners will almost certainly use a water-based emulsion that contains water, clay fillers, latex, polymers, other additives, and either coal tar or asphalt. Paving contractors will likely use coal tar for the majority of applications. Businesses could use asphalt emulsion based for parking lots and walkways, because it has a lower odor. No matter what the application, sealcoating helps maintain the quality and extend the life of paved surfaces we use each day.
How often must you sealcoat Asphalt? You ought to sealcoat your brand-new asphalt the moment it starts to turn grey or 90 days after installation. Should you have already sealcoated your asphalt in the past, it is suggested to re-apply sealer every 3 to 4 years depending on the wear of the previous applications. Should you sealcoat too much voids will be created in the sealer triggering cracking later on. You need to let the old sealer wear off before you apply new sealer. Speak to your local contractor before you make any serious decisions.
A well-paved asphalt surface may last 20-40 years when maintained at proper intervals. Spend less by employing a reputable, paving or sealing contractor. They could create a strategy to maintain your pavement. Spending a little more now, can help you save a lot later on.
