have 1960's vintage house in far south texas. nice polished (white/cream) terrazzo floor in one of the major living area. wall-to-wall carpet in other. we had deduced that a previous owner had knocked out walls to make one large master bedroom out of two bedrooms and a short stretch of hall. now ripping out detested carpeting to install porcelain floor tile. find the two above mentioned bedrooms have polished terrazzo. plan B: forget tile in the bedrooms; keep the terrazzo. however the short stretch of hall, about 4 x 6 ft, is bare concrete at a depth of 0 to 1/8 inch below the terrazzo. what can we economically do that will give a close visual, textural, and hardness match in this area to the terrazzo?
