Normal Seal Coating

Normal seal coating with STAR-SEAL® offers the following benefits:

Protection

STAR-SEAL ® sealant is a heavy-duty refined coal tar sealer that is specifically designed to protect bituminous pavements. Composed of high temperature refined coal tar pitch, select mineral fillers and surfactants, STAR-SEAL® forms a tough, durable and flexible coating that protects asphalt pavements from the damaging elements of weather, water, salts, gas and other petrochemicals.

Appearance

The dark charcoal black color of STAR-SEAL® sealant improves the appearance of new and old asphalt pavements. Unprotected asphalt surfaces gradually lose their rich black color due to oxidation and weathering. STAR-SEAL® preserves the smoothness and resilience of asphalt surfaces and helps hide rough spots, small cracks, patches and surface depressions. Pavements coated with STAR-SEAL® look cleaner because rainfall washes dirt and debris easily from the smooth, non-porous surface. Traffic lines become more visible.

Economy

STAR-SEAL® sealant substantially reduces maintenance costs and at the same time, extends the life of asphalt pavements by as much as 300%. The cost is truly a minor expense when compared to the cost of pavement replacement. Seal Coating also greatly extends the life of existing sound pavements.

Resists Fuel Penetration: Resists gas, oil, salt and chemical penetration. Asphalt is a petroleum derivative, soluble in distillates such as gas, jet fuel and oil drippings. STAR-SEAL® prevents damage from distillates and chemicals.

Prevents Water Penetration

The intrusion of moisture into asphalt pavement structure accelerates its deterioration and is strongly related to pavement distress. The sealing of well-cured asphalt with STAR-SEAL® prevents the seepage of moisture from snow and rain, thus preventing damage from freeze-thaw cycles.

Stops Oxidation

Actinic rays in sunlight can oxidize the asphalt oils in pavement, causing brittleness and a resulting loss of aggregates which may rob up to 50% of the original asphalt thickness in just five years. A pavement seal coated with STAR-SEAL® will resist oxidative degradation and retain its value.

Reduces Costs & Increases Value: The intrusion of moisture into asphalt pavement structure accelerates its deterioration and is strongly related to pavement distress. The sealing of well-cured asphalt with STAR-SEAL® prevents the seepage of moisture from snow and rain, thus preventing damage from freeze-thaw cycles.

Application

STAR-SEAL® sealant must be applied to structurally sound pavements by experienced applicators. Asphalt pavement should be protected by two coats of sealants, however, the quantities and coverage rates must conform to manufacturer’s detailed specifications. Average coverage rates are 0.18 to .20 undiluted gallons per square yard. Latex additive and silica sand may be added for increased traction and durability.
