A water based emulsion, commonly a CQS-1H or equivalent, is sprayed on the new surface with a distributor, overlapping the center line at a rate of +/- 0.5 kg/m². It may or may not be followed by a light coating of a Class IV Sand at a rate of 3-6 kg/m² , depending on traffic requirements.
The end result is a new, inexpensive, black surface that will extend the life of your resurfacing investments.
