Curing Compound Removal

Current airfield specifications call for the removal of all visible curing compound material from the pavement. New concrete appears white when the curing compound is present. When it is properly removed by Hi-Lite's hydroblasters or shotblasters, the concrete appears gray or tan. If there is still evidence of the "white" curing compound after the first pass, our equipment operator will pass the machine over the area until the curing compound is removed and the area is gray or tan.
