SELECTING AND SPECIFYING CONCRETE SURFACE PREPARATION FOR SEALERS, COATINGS, POLYMER OVERLAYS, AND CONCRETE REPAIR

摘要

ICRI Technical Guideline No. 310.2R-2013, "Selecting and Specifying Concrete Surface Preparation for Sealers, Coatings, Polymer Overlays, and Concrete Repair," was recently revised and updated. Many of you are familiar with the new guideline, as numerous copies have already been purchased. But, in case you missed it, the new guideline has been expanded to include surface preparation for concrete repairs. This resulted in the addition of a 10th concrete surface profile (CSP 10) with an amplitude of greater than 0.25 in. (6 mm). Accordingly, a new CSP 10 chip (Fig. 1) has been added to the existing nine CSPs currently used to evaluate concrete surface profile following surface preparation. In addition, Appendix A, "Surface Preparation Selection," has been expanded to provide a detailed selection criteria list and a new Appendix B, "Testing," provides a summary of test methods that may be used to specify and verify the quality of the surface preparation.
