The Product
GemSeal PolyTar is a polymer-modified refined coal tar sealer manufactured by GemSeal Pavement Products. It is designed for commercial and industrial pavements and applied by squeegee or spray at controlled mix ratios.
Why We Install It
At Quality Paving, we install what we would put on our own driveways. GemSeal PolyTar earned its place on our trucks for a few concrete reasons:
Fuel and chemical resistance. Refined tar-based sealers resist gasoline, oil, and hydraulic fluids meaningfully better than asphalt-emulsion sealers. On lots with heavy vehicle turnover, this matters.
Polymer modification. Added polymers improve durability, flexibility, and adhesion, extending the useful life of each application.
Consistent formulation. GemSeal's manufacturing controls produce a predictable, repeatable product. What we test on one lot performs the same way on the next.
Documented technical data. Coverage rates, application temperatures, and cure times are published. There is no guesswork.
What We Look For In Any Sealer
- Verified manufacturer testing and data sheets
- Consistent solids content — no watered-down loads at the truck
- Proven track record in the Southeast climate
- Support and training from the manufacturer
What Installation Actually Involves
- Thorough sweeping and cleaning of the surface
- Oil spot priming
- Crack filling of anything wider than a hairline
- Two coats of PolyTar applied at manufacturer coverage rates
- Sand additive in traffic areas for skid resistance
- Restriping after full cure
The best product in the world fails when installation is rushed. We refuse to shortcut coverage rates or cure times.

Frequently Asked Questions
Is coal tar sealer safe?
Refined coal tar sealers are approved for use in Georgia. Application follows manufacturer guidance for containment and worker safety.
Does PolyTar look different from other sealers?
When fresh, it produces a deep, uniform black finish. Difference from bargain sealers is most visible one year later, not on day one.
How long before I can drive on it?
24 hours minimum for passenger vehicles under normal conditions; longer for cool or humid weather.
