TL;DR
An asphalt emulsion sealer is a driveway sealcoat whose binder is emulsified asphalt rather than refined coal tar, the main alternative since many states and municipalities banned coal tar over its high PAH content. It bonds naturally to asphalt pavement and carries far lower toxicity, at the cost of somewhat shorter life, roughly 2 to 4 years versus 3 to 5, and less resistance to gasoline drips.
What it means
An asphalt emulsion sealer is a driveway sealcoat whose binder is emulsified asphalt rather than refined coal tar, the main alternative since many states and municipalities banned coal tar over its high PAH content. It bonds naturally to asphalt pavement and carries far lower toxicity, at the cost of somewhat shorter life, roughly 2 to 4 years versus 3 to 5, and less resistance to gasoline drips. Quality formulas add sand and polymers for traction and durability. Application is two thin squeegee or spray coats on clean, dry pavement above about 50 F.
