Best Asphalt Driveway Sealer

Best asphalt driveway sealer is asphalt based, due to huge over-performance in eco-friendliness over coal tar based products.

Despite this fact, coal tar products still are most popular, due to the perceived better performance over asphalt based sealers.

That better performance used to be true, but there have been significant improvements in asphalt-based sealers, such as the use of polymers and other additives that increase durability and resistance to oil and gas, that have narrowed that performance gap.

The real reason, however, that asphalt sealers are better is the fact that asphalt-based products are better for air quality due to not emitting high levels of volatile organic compounds (VOCs) like the petroleum-based products do.

Environmental issues aside, according to the manufacturers, the more solids in the sealer formula, the better the sealer quality and the more expensive it is.
