Description
SealMaster® Polymer-Modified Coal Tar Sealer (PMCTS) is a premium quality coal tar emulsion pavement sealer fortified with cross-linking rubber polymers and special surfactants. PMCTS is job-mixed with specifically graded aggregate and applied at a rate of 55-57% solids (unlike conventional sealers that are applied at 40-43% solids).
Surface Preparation
Surface 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 PMCTS in accordance with the following mix design (based on 100 gallons for ease of calculation):
PMCTS 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
For optimum performance and durability apply 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.
Important
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 PMCTS.
Clean Up
Wash tools in water before material dries. |
