One gallon of PMM Concentrate will cover approximately 85-95 square feet (9.4 to 10.5 square yards) per coat when properly mixed as a sand-filled coat and applied.

NOTE: Coverage rate may vary due to pavement age, porosity, and method or application.

PMM is job-mixed with specifically graded aggregate and applied at a rate of 48-55% solids (unlike conventional sealers that are applied at 40% solids). High Solids Formula for Added Durability.

Surface Preparation

Surface prior to sealcoating must be clean and free from all loose material and dirt. Pavement surface repairs should be made with a suitable hot or cold asphalt mix. Cracks should be filled with SealMaster hot pour or cold applied crack fillers. Treat all grease, oil, and gasoline spots or stains with SealMaster Petro Seal or Prep Seal.

Mixing Procedures

For optimum results, mix PMM in accordance with the following mix design (based on 100 gallons for ease of calculation):

PMM Concentrate: 100 gallons
Sand (40-60 mesh AFS): 400 lbs.

NOTE: If required, a small amount of water may be added to facilitate application of mixed material.


For optimum performance and durability apply two coats of PMM with sand. A third coat of PMM with sand may be applied to high traffic areas such as entrances, exits, and drive lanes.


Temperatures must be above 50°F both during application and for a period of at least 24 hours after application. Do not apply when rain is imminent or forecast. New asphalt surfaces should be allowed to cure a minimum of four weeks under ideal weather conditions (70°F) before applying PMM.

Clean Up

Wash tools in water before material dries.
