A light application of a slow-setting asphalt emulsion diluted with water should be applied. In most cases, a dilution of one part emulsion to one part water is used. SS-1, SS-1h, CSS-1, or CSS-1h asphalt emulsions are typically used. Commercial sealers are also available. Those containing coal-tar compounds are not recommended. The diluted material is sprayed or squeegeed onto the surface in a thin, uniform coating. The total quantity of diluted sealant normally applied is 0.1 to 0.15 gallons per square yard. Exact quantities should be based on the surface texture, dryness, and degree of cracking or raveling.
Excess application must be avoided since this may result in pick-up on shoes or tires. Vehicles must be kept off the seal until it is absorbed into the existing surface.
