EVALUATION OF MASONRY COATINGS

THIS REPORT DESCRIBES THE EVALUATION OF FIVE COATING SYSTEMS TO REPLACE THE CONVENTIONAL CLASS 2 RUBBED FINISH NOW REQUIRED ON CONCRETE STRUCTURES. TEST SPECIMENS WITH EACH OF THE FIVE COATINGS WERE PREPARED; ABSORPTION, FREEZE AND THAW DURABILITY, ABRASION, AND ACCELERATED WEATHERING TEST WERE CONDUCTED; AND THE RESULTS WERE COMPARED WITH SPECIMENS HAVING A CLASS 2 RUBBED FINISH. FOUR OF THE FIVE PROVED ACCEPTABLE AS A REPLACEMENT FOR CLASS 2 RUB. THE FIFTH EXHIBITED EXCESSIVE SCALING DURING THE FREEZE AND THAW TESTS. IT WAS RECOMMENDED THAT THE FOUR ACCEPTABLE COATINGS BE PLACED ON AN APPROVED PRODUCTS LIST AND USED AS ALTERNATES. ALL FIVE COATINGS ARE NOW BEING FIELD EVALUATED ON A STRUCTURE IN BATON ROUGE. /AUTHOR/
