ABSTRACT:
A cementitious facing material for bonding to either preformed masonry building units or to existing masonry and concrete walls, floors or slabs; comprising a suitable proportioned dry mixture of (1) white Portland cement, (2) washed and screened sand of glass making quality, and (3) paint pigments. These thoroughly mixed dry materials are activated into a moist colored concrete mixture of troweling consistancy by the addition of a wetting agent in the correct proportions of water and polyvinyl acetate resin emulsion (containing approximately 50% of solids). The proportions of water and resin in the wetting agent to be based upon the desired percentage of resin to be retained in the facing material after it has been cured. A coating of bonding material is applied to the face of the preformed masonry unit or to the existing masonry or concrete wall, floor or slab and the facing is applied over the bonding material and bonded to the existing base. The composition, when applied as a facing and allowed to cure, forms a water-resistant, wear resistant, resilient, tough, uniformly colored facing having the appearance of fine grained concrete.
