Protection:
STAR-SEAL® 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 petro-chemicals.

Appearance:
The dark charcoal black color of STAR-SEAL® 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® substantially reduces maintenance costs and at the same time, extends the life of asphalt pavements by as
much as 300%. The cost of STAR-SEAL® is truly a minor expense when compared to the cost of pavement replacement.
STAR-SEAL® 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.
rain
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.
sun
Stops Oxidation
Actinic rays in sunlight can oxidize the asphalt
oils in pavement, causing brittleness and a
resulting loss of aggregates that may rob up to
50% of the original asphalt thickness in just five
years. A pavement sealcoated with
STAR-SEAL® will resist oxidative degradation
and retain its value.

Application:
STAR-SEAL® must be applied to structurally sound pavements by experienced applicators. Asphalt pavement should be
protected by two coats of STAR-SEAL®, 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. STAR MACRO-FLEX®, latex
additive and silica sand may be added for increased traction and durability.
