Environmental regulations are accelerating the shift away from coal tar-based asphalt sealers, creating demand for alternative maintenance products. A commercial-grade asphalt emulsion sealer supplied in 55-gallon drums is positioned for professional contractors maintaining driveways and parking lots. Product specifications describe a non-hazardous formulation that contains no volatile organic compounds and is intended to restore pavement color while extending surface life.

The sealer is based on asphalt and is described as a replacement for coal tar products, which have faced increasing restrictions. The formulation is listed as a non-hazardous material and is recognized in some states as an environmentally preferable sealing option, according to product specifications.

Its stated purpose is to renew the deep black appearance of aged asphalt and to help protect the surface from wear. The product is supplied ready to use in 55-gallon drums for commercial applications.

One drum covers approximately 5,500 square feet when applied with a spray system, according to the specifications. The product is ready to use and requires no dilution under normal conditions; dilution of no more than 5% is suggested only when spray equipment does not perform properly.

Application is possible with either a professional spray system or a squeegee. The product must be stirred thoroughly before use with a mechanical mixer or wooden stick to prevent asphalt solids that settle during transport from causing an uneven coating.

Walking traffic can generally resume within three to four hours in dry, warm weather. Light vehicle traffic should be kept off the surface for 24 to 48 hours, and full curing takes about 72 hours. Cool or damp conditions can extend these intervals.

Product guidance cites batch purchasing of at least four drums as a way to reduce per-drum costs and maintain material continuity on larger projects. The sealer is described as suitable for routine maintenance as well as larger parking lot repairs.

For improved skid resistance, the guidance suggests mixing an appropriate amount of slate powder or sand into the sealer during application. Coverage can vary with the application method and pavement condition; dry, old, porous gray asphalt may absorb more material and reduce the actual area covered.
