Directions For Use:

New  concrete should have cured until the shrinkage and moisture movement is low, and possesses a porous and textured surface with all curing compounds and sealers removed. Old concrete must be clean and well textured. All oil, dirt, debris, paint and unsound concrete must be removed. The surface must be prepared mechanically using a scabler, bush hammer, shot blast or scarifier which will give a surface profile of a minimum (3 mm) and expose the large aggregate of the concrete. The final step in cleaning should be the

complete removal of all residues with a vacuum clean- er or pressure washing. Acid etching is acceptable only when Mechanical preparation is impractical. It is recommended only contractors experienced in the acid etching process use this means of the surface prepara tion. The salts of the reaction must be thoroughly pressure washed away. Allow the concrete to dry completely
