Description
PMB™ is a polymer-modified, clay stabilized coal tar pitch emulsion pavement sealer fortified with specialty surfactants to promote superior adhesion and durability. PMB™ is job mixed with select aggregate to produce a superior skid-resistant wearing surface.
Surface Preparation
New asphalt surfaces must cure a minimum of four weeks under ideal weather conditions before application. Surface must be clean and free from all loose material, dirt, and dust. Cracks should be filled with SealMaster® Hot Pour or Cold Applied crack fillers. Treat all grease, oil, and gasoline stains with SealMaster® Petro Seal or Prep Seal.
Mixing Procedures
• Sand-Filled Coats: For optimum results PMB™ shall be mixed in accordance with the following mix design (based on 100 gallons for ease of calculation):
PMB™ Concentrate..............100 gallons
Sand*...................................400 - 500 lbs.
*(40-60 mesh AFS)
NOTE: If required, a small amount of water may be added to facilitate application of mixed material.
• Primer Coat: For use as a primer (without sand) use the following mix design:
PMB™ Concentrate..............100 gallons
Water....................................20-25 gallons
Application
For optimum performance and durability apply one primer coat of PMB™ and two coats of PMB™ with sand. A third coat of PMB™ with sand may be applied to high traffic areas such as entrances, exits, and drive lanes.
Important
Both surface and ambient temperature shall be a minimum of 50°F. Temperature shall not drop below 50°F in a 24 hour period following application. New asphalt surfaces should be allowed to cure a minimum of four weeks under ideal weather conditions (70°F) before applying PMB™.
Clean Up
Wash tools in water before material dries. |
