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.
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.
Application of Sealcoat
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.
Wash tools in water before material dries.
