What Is Sealcoating?

MA Outdoors Corp - Professional Paving, Asphalt Repair & Masonry Services Greater Boston

Sealcoating is the process of applying asphalt sealer to asphalt pavement. Over time asphalt cement wears away due to rain, U.V. rays, and chemicals. The asphalt sealer applied on the pavement provides a protective layer keeping out those elements. Sealcoats are typically bituminous based products or acrylics. The sealcoat is in a liquid formulation of one of the above emulsions, mixed with water, silica sand, polymer additives, and other proprietary fillers and solids. It is applied by brush, squeegee, or spray.

What is the Sealcoating Process?

The first step is to thoroughly clean the asphalt pavement of any moisture, dirt, or organic materials. We use leaf blowers, power washers, and power brooms to clean the driveway. Then we tape off any pavers, fences, and edges of buildings that touch the asphalt. We do this to ensure no sealer gets on any surface other than the asphalt. We apply some sealer around the edges with a small broom and then use a large squeegee to apply sealer to the rest of the asphalt. After the sealer is applied we caution tape the area off to prevent people from walking or driving on it for 24 to 48 hours while it dries.
