• Abstract:
  This report describes the evaluation of five coating systems to replace the conventional Class 2 rubbed finish now required on concrete structures. The evaluation consisted of preparing test specimens with each of the five coatings and conducting absorption, freeze and thaw durability, abrasion and accelerated weathering test and comparing the results to test specimens having a Class 2 rubbed finish. ; The conclusions reached from this study were that four of the five systems would be acceptable as a replacement for Class 2 rub. The only system that did not perform satisfactorily exhibited excessive scaling during the freeze and thaw tests. ; The recommendations are that the four acceptable coatings be placed on an approved products list and used as alternates, and that a field installation be made using all five coating systems to confirm and supplement the laboratory findings.
