Concrete profiling

摘要

For proper bonding of overlays and coatings to a concrete substrate, it is important that the surface of the concrete floor is properly prepared. Preparation of the surface is commonly known as profiling, and concrete surface profile (CSP) is a standardised measure for the roughness of a surface established by the International Concrete Repair Institute (ICRI). It is expressed with a number from one to nine, where nine represents the roughest finish possible. There are several methods to obtain the ideal CSP for your application, which can be grouped in two broad categories: mechanical and chemical.
