Significance and Use
5.1 For proper bonding of overlays and coatings, it is important that a concrete surface have the correct surface profile. This test method allows one to obtain a permanent replica of the concrete surface, which can then be compared to visual profile standards, or evaluated quantitatively for profile depth. The permanent replica may also prove useful in resolving future disputes.
1.2 A profile can be imparted to concrete by various methods such as blast cleaning and acid etching. The depth of the surface profile has been shown to be a factor in coating adhesion and performance.
1.3 The International Concrete Repair Institute (ICRI) provides a means of visually judging a concrete surface by use of nine different visual comparators called Concrete Surface Profiles (CSP). This standard compliments the use of these visual comparators.
