The Sealcoating Process
- We remove all dirt and debris from the asphalt with power blowers, scrapers, and metal wire brushes. Debris can consist of dirt, dust, grass clippings, mulch, pebbles, moss, small puddles, and grass growing in cracks (in some instances we ask our customers to spray grass growing through the driveway with weed-killer).
- We then treat all fresh oil (or any oil based chemical) stains with petro-seal primer. The primer covers the stains, and permits the sealer to bond with the asphalt. Old oil stains are easily covered by our sealer, and therefore do not need to be primed.
- Any large cracks (ΒΌ" or greater) will be filled with liquid or trowel grade crack filler, depending on the type of crack. Smaller hairline cracks are sealed by the sealant itself. (Florida customers: we do not pre-treat cracks. We sealcoat each driveway with a heavy sand fortified mixture.)
- After properly preparing the asphalt, our experienced crews apply a rubberized coal tar emulsion to your driveway with squeegees. In just 24 hours your driveway is ready for use.
Star-Seal is a heavy-duty refined coal tar sealer that forms a tough, durable,and flexible coating that protects asphalt pavements from the damaging elements of weather, water, salts, gas, and other petro-chemicals.
Star-Seal is composed of high temperature refined coal tar pitch and select mineral fillers and surfactants. Star Macro-Flex polymeric latex additive is added to the sealer to enhance latex properties and speed drying time.
Star-Seal meets or exceeds:
- Federal Government Specification RP-355e (GSA-FSS), June 1987.
- United States Air Force and F.A.A. specifications.
- State Specifications USINF coal tar emulsions for government projects and bridge decks.
- American Society for Testing and Materials (ASTM) D-3320-74T and D-490, COKE oven tar specification.
Sealer Application
Most companies apply sealer with spray units instead of by hand. Spraying the sealer can produce a much thinner coat which reduces the materials costs for these companies. Hand sealing provides a substantially thicker coating than even two coats with spray. Many fly-by-night companies cut their costs even more by using materials that do not approach the quality of Star-Seal.
In addition to being thin, spraying can be messy, and leave black tar on brick, concrete, and your garage. Our experienced sealers spread the sealer from the center to the sides. Their skill and care ensures that your brick, garage, and concrete will be tar free.
Our crews use brushes and squeegees to apply a thick, rich coat of Star-Seal to your driveway. Don't be fooled by the fast-talking door-to-door solicitors. Ask for your driveway to sealed by hand. Ask for your driveway to be sealed by Collegiate Sealers.
