Rejuvenating Fog Seal

Find a Contractor/Supplier


Rejuvenating seals may be emulsions of rejuvenating additives and may include asphalt, polymers, and other additives.


Equipment Variations

A properly calibrated emulsion distributor or a hand sprayer can be used for spraying emulsions.

ASTM D-2995 can be used to estimate emulsion application rate and residual application rate.

Material Variations

Rejuvenating emulsions are often diluted with water prior to application to reduce viscosity for spraying. Dilution is performed in varying proportions - up to 1 part emulsion to 5 parts water, but in most cases, a one-to-one dilution is used.

  • Dilution may be improved by pre-warming the dilution liquid to 25 to 90° C (77 to 194° F).
  • Never add emulsion to water, always add water or other diluent to emulsion.
  • Diluted emulsions are normally not stored, unless bad weather necessitates temporary storage.
  • Water for dilution should be clean, potable water, free from detectable solids or incompatible soluble salts.
  • Test for dilution incompatibility, whenever in doubt, by diluting the emulsion in the severest conditions anticipated (e.g., high dilution, cold water, hard water, high shear pumps).
