What is a seal coat?
Introduction
Product Used
Specifications
Application
-
An application of asphalt emulsion to the surface of the pavement
-
It has a deep, rich black color which gives old, oxidized pavement a “like new” surface
-
This melts snow and ice faster, and reduces cleaning and maintenance costs; beautifies the pavement surface
-
Protects pavement from:
-
Oxidation
-
Moisture intrusion
-
Fuel damage
-
Oil damage
-
-
Premium quality coal tar emulsion
-
Polymerized with cross-linking rubber polymers and special surfactants (soaps)
-
PMCTS is added to specifically graded aggregate
-
Rate of application: 55-57% solids (unlike conventional sealers that are applied at 40-43% solids)
-
Aggregate: Provides a safe, skid-resistant surface
-
Benefits: PMCTS dries faster than conventional pavement sealers that are diluted with water prior to application
-
Shall not be applied when the temperature is expected to drop below 50°F at any time within a 24-hour period after application
-
It does not contain asbestos
-
An environmentally friendly water-based pavement sealer
-
It contains <50 grams per liter volatile organic content (VOC)
-
Meets the following testing requirements:
-
ASTM D 140, ASTM D 466, ASTM D 490, ASTM B117, ASTM D 529, ASTM D 2939, and ASTM D244 procedures.
-
-
Two coats of PMCTS with sand
-
A third coat of PMCTS with sand may be applied to high traffic areas such as entrances, exits, and drive lanes
-
PMCTS Concentrate + Sand + Water (if needed)
-
Rate: 0.11 to 0.13 gallons per square yard (70-82 square feet per gallon) per coat
-
1 gallon of polymer mix will cover: ~85-95 square feet (9.4 to 10.5 square yards) per coat
-
Coverage rates may vary due to pavement condition, age, and porosity
