Concrete Surface Profile (CSP) is the measure of the average distance from the peaks of the surface to the valleys as seen through a cross-sectional view of the concrete surface. The standards are rated 1-9 with 1 being the smoothest and 9 being the roughest.
The CSP is important to consider when trying to achieve proper bonding of concrete overlays and coatings. Generally, when using a thick overlay, the CSP needs to be higher. When using a coating that is slim, a smoother CSP of 2 to 4 is correct. When using thicker self-leveling and polymer overlays, the appropriate CSP will range from 4 to 6.
EDCO’s line of Surface Preparation, Repair and Restoration Equipment has the ability to leave the desired CSP and finish. With the proper machine and accessories, EDCO’s products can leave a CSP from 1 to 9. Below is a chart to show which products will most effectively achieve the desired CSP and finishes.
