  • Industry Guidelines for Creating Surface profiles?

    The International Concrete Repair Institute (ICRI) has created a technical guideline #03732, “Selecting and specifying concrete surface preparation for sealers, coatings, and polymer overlays.” This guideline provides concrete surface profiles of CSP 3 to 9 which are used under the following conditions.

    • •For coating applications from 4–5 mils in thickness, the surface profile shall be a CSP 3. This is known as a light shotblast.
    • •For coating applications from 15–50 mils in thickness, the surface profile shall be a CSP 4 or 5. This is known as a medium shotblast.
    • •For coating applications from 40 mils to 1⁄8″ in thickness, the surface profile shall be a CSP 5 or 6. This is known as a medium-heavy shotblast.
    • •For topping applications from ¼” to ½”, the surface profile shall be a CSP 6 or 7. This is known as a heavy shotblast.
    • •For concrete overlays greater than ½”, the surface profile shall be a CSP 8 or 9. This is known as an extreme shotblast.

    *Industry test results indicate that this Concrete Surface Profile offers no improvement in adhesion with overlays, compared to that of CSP 7.
