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 nom…inal 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 RestorationA 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 …finish. 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.
Answer I would use ice cubes for the glue and toilet bowl cleaner for the yellow stain Depending on the stain there are different steps. But I will assume that you… are talkin about the stain from the glue. You can take a stripper to the floor to remove the glue. From there you will need to either polish it or wax it. If it is a high traffic area I would not suggest waxing. As this will need to be done often. The more wax you apply the worse it will be to strip it later and do it the right way. The process for polishing it is rather easy. You do need to know some basics though. How to run a floor machine or as most people call it a buffer. They have these relatively new pads that make the process easier than it was in the past. HTC makes a brand called TWISTER. They are diamond embedded. Basically you start with your red pad then white then yellow then green. They can be used dry but it is better to do it wet. Cuts down on the dust and does give it a better finish in the end. Obviously it is harder than it sounds from reading this so getting a professional involved may be your best option.
Granolithic Floor is a marble type mosaic floor finish that uses Portland cement as base materials. It has a characteristics of durability, beauty and variety installed in eit…her by: a. Monolithic or cast in place - means massively, solid, single and uniform floor finish cast in place. A mixture of cement and marble chips to a proportion of 1:3 is casted on top of a rough floor slab surface to an average thickness of 1.25 cm. the floor is then grinded after it has attained sufficient hardness to withstand abrasion and vibration caused by the grinding machine. Grinding of the floor surface should not be allowed earlier than 48 hours after casting. b. Pre-cast - refers to granolithic tiles in various dimensions hydraulically pressed and molded in a factory. The distinctive difference between the cast in place and the pre-cast installation is the manner and place of casting or molding. The former being installed on site and the latter at the factory site. Thus, pre-cast is installed in a tile form while cast in place is installed in a fresh mixed form.

I have spoken to a builder friend about this as we are wanting to remove our old terrazzo floor in the bathroom. He said you would need to jackhammer it out.... i am a l…ittle hesitant as the bathroom is on the 2nd floor of our home with hardwood floors beneath.. i have time to spend on it as we have another functional bathroom in the house, so i am planning on using a hammer and chisel to get it up.....
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 have recently learnt abit about laying granolithic floors basicaly what you have to do is lay it same as a normal screed then when the water comes to the top you have to go …over it till its gone then wait until water comes back up and keep repeating this process until no more water comes back up
35 years with medium duty usage
No PineSol wont damage Terrazzo.
oil on Terrazzo is not a good idea
Terrazo is basical a cement floor with a high polish, you can scrape pretty agressivly and you can use paint remover, wont hurt the terrazzo
First of all is the space commercial or residential? My initial thought is-- well yes-- if you are talking about a floating wood floor.... But I will have to say that this ter…razzo better be pretty darn ugly before covering it. Terrazzo is one of the most exspensive and durable floorings money can by. As a rule well cared for terrazzo flooring adds value to any commercial or residential space.
•Concrete-based flooring such as granolithic flooring can withstand extreme loads, making it a good choice for warehouses, factories or other workplaces that store…, make or use heavy objects. The relatively inexpensive materials and labor required can also appeal to budget-minded builders. Unfortunately, these kinds of floors can cause some problems even as they solve others. The tendency for sounds to reflect off the hard concrete surface, for instance, leads to noise problems. The floors can also prove hard to clean and feel constantly cold.this ans. by ritesh patel :-no.8980262094
