Chances are that if you have properties with asphalt you are probably familiar with the term Sealcoating. If not, read on to gain a better understanding of what sealcoating is and why we use it. We will not only explain what is but also how it works, when you should use it, and the costs associated with it. Our hope here is to provide an introduction to sealcoating so you ask the right questions when searching for a qualified paving contractor to complete your project.
What is Asphalt Sealcoat?
Asphalt sealcoat is a blend or liquid fillers and tiny solid particles of sand that when combined protect and restore asphalt pavements. Sealcoat is generally made from dissolved asphalt, fillers and water. It is applied with rollers, brushes, or with spraying application.
Sealcoat is made up of the same materials and compounds found in asphalt. When sealcoat is applied to asphalt it helps to refinish and protect the asphalt surface while enriching the asphalt that has become dry and brittle over the years. The small mineral particles in Sealcoat fill in gaps and cracks to strengthen and level the pavement surface. The result is an application is restored and even pavement. Like sunscreen, the sealcoat application protects the asphalt from the sun, chemicals and daily wear and tear.
Why use asphalt seals?
Sealcoating asphalt is not a requirement for an asphalt application; however, it does provide several benefits. As such, you should consider your specific application and consult with a trusted local paving contractor to determine if its right for you paving project.
Although not a necessary aspect of regular asphalt maintenance, sealcoating a parking lot or driveway can offer some benefits. UV Rays and oxidation are two factors that shorten the life of asphalt pavements. Both elements erode the asphalt making it crack and crumble. Cracks allow water to enter the pavement and damage it further while causing soil erosion beneath the pavement. This can result in costly potholes and pavement damage. Car fluids, snow, ice and rain also contribute to shortening the pavement’s lifespan.
