Finish Line Floors has served: St. Petersburg, Clearwater and the Tampa Bay area since 1989. Learn it's history, how terrazzo is made, and the process of restoring old terrazzo. Terrazzo is a rough cut marble floor. In the past, wax and acrylic finish was used as a sealer and gloss. Stripping, sealing and waxing is still the preferred cleaning process for supper markets like Publics. Seldom will any scrubbing, cleaning and bleaching return residential terrazzo to it's original condition. Now, diamond abrasives are grinding, honing and polishing stone more efficiently than ever before and is why we see so much granite in our kitchens today. Diamond grinding has brought terrazzo to new levels of gloss for another generation. Terrazzo Floors Nothing makes as much difference in a home's appearance as a clean and newly refinished Terrazzo floor. Easily maintained and inexpensively refinished after years of use, Terrazzo is a floor built to last a lifetime. About Terrazzo originated and gets its name from the terraces of fifteenth century marble and mosaic workers, who were using leftover marble chips to create a natural and beautiful pavement. In 1931 the Terrazzo And Mosaic Association set the standards for the Terrazzo we find in our homes today. Two parts marble chips and one part Portland cement, Terrazzo is poured over the foundation before the interior walls are in place. After pouring and pressing with rollers, Terrazzo is ground to an 80 grit finish. Terrazzo is a continuous marble floor that is 5/8" thick and at least 70% marble on the surface. Unlike most floors, Terrazzo can be refinished to a higher gloss than it had originally 40 years ago. Applications of acrylic finishes have been the standard means of sealing and finishing Terrazzo. Recently, honing and polishing with diamond abrasives have established new levels of gloss that reveal the natural beauty of the stone, creating a polished marble floor. Preparations - Avoiding Damage Care must be taken when removing floor coverings to minimize damage and expense. Remove carpets by pulling back the corners and cutting the back into five foot strips with a razor knife. DO NOT PULL NAILS!! Nails holding down tack strips must be cut or ground to floor level. Pulling a nail will pull a piece of the Terrazzo creating a costly repair. Do Not Use Acid Cleaners! Acids will damage the floor, etching and making the floor porous. The Process Once the preparations are complete, grinding nails, patching holes, removing tile or sheet products etc., the grinding process can begin. Diamond abrasives of various types and coarseness are used. Starting with an aggressive segmented metal bond diamond for cutting through wax, glue and stains. Followed by a series of resin matrix diamond abrasives ranging from 30 grit to 400 grit for smoothing, honing and the beginning of the polishing process. The 6 grinding, honing and polishing steps are done with water to minimize dust and the slurry is vacuumed off the floor with each pass. After overnight drying, the final process can be completed. Recrystallization is a chemical process that seals the floor and creates a high gloss that is harder than the stone itself. Maintenance The recrystallized Terrazzo is easily maintained and will last 4 or 5 times longer then the acrylic finish. With professional periodic buffing, recrystallized Terrazzo will last many years. Use good sand catching door mats, and shake them out often. Stick felt pads under furniture and dining room chairs, etc. Damp mop with 2 - 3 oz. of vinegar or non sudsy ammonia per gallon of water. Do not apply wax or other coatings on recrystallized Terrazzo. Professional buffing, once each year or two, will extend the crystallized Terrazzo floor for many years to come. Terrazzo restoration cost less than most carpets.
