Polymer Modified MasterSeal (PMM) Tech Data

Product Description

Polymer-Modified MasterSeal (PMM) is an environmentally friendly mineral filled asphalt emulsion pavement sealer blended with polymers and special surfactants for superior adhesion, flexibility, and durability. Polymer-Modified MasterSeal is a higher solids, faster drying pavement sealer designed to protect and beautify asphalt pavement. Polymer-Modified MasterSeal is formulated to be job-mixed with aggregate. Polymer-Modified MasterSeal meets ASTM D8099/D8099M-17 Standard Specification for Asphalt Emulsion Pavement Sealer. PMM also meets FAA Item P-623 specification for Emulsified Asphalt Spray Sealcoat.

Recommended Uses
Polymer-Modified MasterSeal is ideal for all types of pavement surfaces including parking lots, shopping malls, airports, driveways, roadways and more.

Estimated Material Requirements
One gallon of Polymer-Modified MasterSeal will cover approximately 85-95 square feet (9.4 to 10.5 square yards) per coat when properly mixed and applied.

Application Rate of Mixed Materials
Apply properly mixed PMM (PMM and sand) and at a rate of 70-82 square feet (7.77 to 9.11 square yards) per gallon. Application rates may vary due to pavement porosity and method of application.

Performance Characteristics

Surface Preparations
Surface must be clean and free from loose material and dirt. Cracks should be filled with SealMaster Cold Pour or Hot-Applied Crack Filler. Oil stains should be cleaned and primed with SealMaster Oil Spot Primer.

Mixing Procedures
Mix PMM in accordance with the following mix design (based on 100 gallons of PMM for ease of calculation):
PMM………………………… 100 gallons
Sand (40-70 mesh)……………200-400 lbs.

Application Equipment
Properly mixed PMM shall be applied by mechanical squeegee/brush equipment or spray equipment capable of spraying coatings with sand. Equipment shall have continuous agitation or mixing capabilities to maintain homogenous consistency of mixed material throughout the application process. Truck mount or self-propelled squeegee/brush equipment shall have at least 2 squeegee or brush devices (one behind the other) to assure ad-equate distribution and penetration of mixed PMM into bituminous pavement. Hand squeegees and brushes and brushes shall be acceptable in areas where practicality prohibits the use of mechanized equipment.

Application Procedures
For optimum performance and durability apply a mini-mum of two coats of properly mixed PMM. A third coat of mixed PMM may be applied to high traffic areas such as entrances, exits, and drive lanes for added durabil-ity. Allow each coat to dry thoroughly before applying successive coats. Allow final coat of PMM to dry for 24 hours prior to opening to vehicle traffic.

Application Conditions
Mixed PMM shall not be applied when temperature is expected to drop below 50°F during application and for a period of at least 24 hours after application.

Line Striping and Traffic Markings
Use SealMaster 100% Acrylic Traffic paint for line striping and traffic markings.

Cautions
Both surface and ambient temperature shall be a mini-mum of 50°F and rising during PMM application. Do not apply if temperature is expected to drop below 50°F within a 24 hour period after PMM application.

Packaging and Availability
PMM is available in 5-gallon pails, 55-gallon drums and bulk tanker load quantities. PMM is supported by a national network of SealMaster manufacturing facilities along with a national network of qualified applicators.
