Contaminants and oils should be removed from the surface of the concrete by using detergents or mechanical means ( such as shot blast, diamond grinder, Roughening, abrading, Sandblasting, etc.) in order to obtain a completely clean surface. If detergents are used, rinse the concrete with mains water until a neutral PH value of the surface is obtained, and then leave the surface to dry.
Surface should be free from laitance & dust trace of grease, oil moisture. The concrete surface should be clean dry and mechanically sound.
Apply the first layer of the coating, such as an epoxy primer specifically formulated for penetrating and bonding to the concrete. Usually 150 microns in thickness.
1-2 mm thickness self levelling
3-5 mm thickness of mortar screed
Seal the holes opens up during mortar screed.
Topcoat of 500 micron
1-2 mm thickness
