Sealcoating is the process of applying a coal tar emulsion over an asphalt pavement. Also known as pavement sealing, this process applies a new protective coating to an asphalt pavement to protect against oil, water, and UV damage. Regular asphalt sealcoating in Austin, Texas can double the lifespan of your asphalt lot or driveway with significant cost savings.
Your asphalt surface is essentially gravel, rock, and binder material called asphalt cement that holds the aggregate together. Asphalt cement is made by distilling crude oils. Over time, chemicals, UV exposure, and rain all degrade the binder and cause deterioration of the asphalt surface and brittleness.
Asphalt sealcoating creates a barrier to reduce this damage and extend the longevity of the asphalt surface. A new sealcoat also improves the appearance of your asphalt with a bright, black finish.
Sealcoats are typically liquid formulas made from acrylics or bituminous-based ingredients that are applied with a squeegee, spray, or brush. There are many varieties of asphalt sealers, each with different applications and benefits.
