Composition: The floor consists of an under layer of cement concrete in ratio of 1:2:4(1 part of cement: 2 parts of coarse sand: 4 parts of graded stone aggregate 12.5 mm nomi…nal size). Its thickness depends on size of marble chips used. Under Layer Cement concrete mixture should be used for under layer. The panels should be of uniform size. In exposed situations, length of any side of the panel should not be more than 1.25m. Terrazzo Restoration A terrazzo floor is the same as any concrete slab with a few exceptions. It is often placed over a concrete slab in a thin layer, from a half to three quarters of an inch in thickness. It is seeded with with colored marble chips on the surface while the mix is fresh, and the chips are seated in during the floating or troweling process. After the mixture hardens, the polishing process begins. Large floor grinding machines using diamond chip impregnated cutters polish the surface in steps from coarse to fine. You now have a beautiful terrazzo floor, but highly susceptible to staining. Most contractors place one or two layers of sealers on the finish but this is not enough. In a school system where I performed this installation, we had to take great precautions to protect the floors. Then, upon occupying, the school personnel stripped off the sealer and applied multiple layers of floor wax per manufacturer's recommendations. Therefore, in order to restore a terrazzo floor one must first strip and clean all waxes, sealers, dirt and grime. Then you have to consider whether repolishing the surface will remove stains and imperfections which sometimes penetrate very deep into the surface. Then, if repolishing won't do it, you must consider removing the floor and reinstalling it. But before I did that, I would aggressively clean the surface and then do a proper job putting down layers of floor wax. Often the sheen from this procedure, especially after a thorough cleaning of the old floor, will conceal most imperfections. See the related link(s) listed below for more information:
Cleaning terrazzo floors Traditionally known as Strip, Seal and Wax.. Terrazzo is two parts marble chips in one part portland cement, 5/8" thick and ground to an 80 grit fi…nish. Wax and acrylic finishes have been used to seal and gloss terrazzo for the last 50 years. For the past ten years a new improved more environmental friendly process has been developed. No need for any type of sealent, polishing to the original stone finish looks feels and cleans better then the traditional strip seal and wax method. To get more information on this process and service visit boylanmarblerestoration.com we eliminate all the steps to come. Removing the old finish is the first step. Floor strippers (strong detergents) are available in hardware stores, janitorial supplys and tool rental outlets where you may rent floor scrubing machines along with all the accessories. Once the floor has been stripped, you will find stains that require more attention. A strong hydrogen peroxide will bleach organic and mineral stains. The most available source is your local salon or beauty supply. Purchase 40 volume cream developer used for bleaching hair. The peroxide must sit on the stain 8 hours for best results. Try a few test spots. Peroxide will not remove the oil based stains from petrolium products; carpets, pads and adhesives. If you are removing carpets, do not pull the tackstrip nails or drive them into the floor. In most cases, the nails are aluminum and will sheer off with a hammer and sharp chisle. Steal nails must be cut off using a grinder with a thin blade.. Resealing and waxing by mopping on four thin coats of acrylic finish will give you a good foundation. Now you will be cleaning the finish not the floor. Use cleaners sparingly. Periodicly, remove the top coat and reapply another thin coat.

First off, you need to find a wax stripping product, one that is designed for terrazo floors. You can use that to clean the floor. Removing the wax isn't a big deal when you c…arefully follow the instructions. After that, use water to wash off the traces and residues of the wax-stripping product. You can dry the floor after that. Next, you can apply the terrazo floor sealer. This is a helpful step as doing that can help in protecting the unsightly stains. Once the sealer is applied you can let it to dry completely. Do not apply too much as one thin coat is enough to get the job done. It is important to keep the dust away from the flooring because the quality of dust can result in scratches. So you need to sweep the floor regularly using a dust map or a broom. Also, get a dust cleaner that has neutral pH. Along with a cleaner, combine 3 gallons of water. Apply the mixture on the floor and let it be there for a few minutes. Rinse the mixture and rinse the floor until there are no map lines seen. Once the floor is mopped entirely, prepare the buffing machine and then use it on the floor.

I used to put a layer of paper towels down on the stain, then drip bleach straight from the bottle on the towels until the towels were soaked all the way through. Let them sit… on the floor for about 5-10 minutes then wipe them up.
