Abstract:
The Michigan Stadium steps of the University of Michigan, Ann Arbor, have been repaired and maintained with an annual program of applying a masonry topping and sealer. An Ann Arbor contractor first removed all loose, deteriorating concrete with chip-ping guns, cleaned the surface with high-pressure water, applied a coat of inorganic penetrant, then a special mix mortar bond coat, and a final application of a zero-slump top coat of special mix mortar. Within 10 min of final troweling of the top coat, a curing com-pound was applied to the surface, followed at a later date with a final cleaning and application of an in-organic seal coat.
