Relationship between Surface Texturing Method on Concrete Floor and Adhesion of Floor Coatings

Abstract

Recently, Separation of floor coatings is frequent in hard concrete floor finished by machine trowel. In this report, we examined adhesive properties within the floor coatings between concrete surface using test pieces which are finished by any different method like field. As a result, it was clarified as follows. (1) The finishing using machine trowel decreases the adhesion strength of floor coatings comparing with hand trowel. (2) Deep scratch on concrete surface Increases the adhesion strength of floor coatings.
