All asphalt coatings and sealers are not created equally... GemSeal uses only tested and certified raw materials in a sophisticated colloid milling process to produce the most consistent asphalt sealing products like PolyTar, Fed-Spec, Guardian AE (asphalt emulsion) and Pro-Blend for even applications of your asphalt maintenance opportunities. Our rigorous quality control program ensures our sealers meet the highest standards to eliminate call backs and costly re-applications contractors often experience with lower quality products.
- GemSeal PolyTar has a proven 25-year track record in the field as the longest lasting asphalt pavement coating available in the market today.
- GemSeal FedSpec sealer is certified and tested to meet or exceed federal specification ASTM D5727 (formerly RP-355e) and FAA specifications. Our formula ensures proper solids, ash content and viscosity for a job well done.
- GemSeal's Guardian AE (asphalt emulsion) provides a highly durable protective coating that is pigment-enhanced for commercial and residential applications. Polymeric formula enhances adhesion and durability. Provides contractors another high quality sealer option for those markets that prefer asphalt emulsion sealers.
- GemSeal Pro-Blend is a durable, protective coating for commercial applications. Pro-Blend offers maximum adhesion and durability.
