What is terrazzo?
Terrazzo is a flooring material. It is made up of chips comprised of marble and granite. The chips are set and concrete then polished to leave a smooth surface. It tends to be long lasting and can be refinished.

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 nominal 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: (MORE)
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. (MORE)
How do you remove carpet tacking nails from the terrazzo floor without breaking the surface of the floor?
In order to retain terrazzo and minimize damage - I'm about to try this method as interpreted from Ross of Home Depot South Tampa: After removing the soft wood portion of the tacking strip away from the nails without disturbing the nails,. (A) then clamp the nail with one of a variety of pliers ava…ilable and gently to moderately forceful, twist each nail in place until the nail is loosened so that it can be pulled directly vertically without chipping or breaking the terrazzo/marble. Then fill nail hole with appropriate adhesive-filling is optional depending on desired appearance.. (B) In some cases the nail may break, the remedy then is to cut the nail flush at floor level with special pliers (maybe $10) and then grind down (dremel) the nail flush to the floor and leave in place. The snap cutting of all the nails and grinding could avoid the twist method and minimize floor chipping and whole filling.. Whichever method, it may be difficult to avoid some terrazzo chipping which may be cured by applying a selected sealant/adhesive, consider color and hardness desired. Start in an undesirable corner - thoughtful trial & error is progress and refinement. (MORE)
You can remove battery acid from terrazzo by sprinkling some bakingpowder on the affected area and scrubbing the stain with a wettoothbrush. Wipe away the chalky residue with a clean, damp cloth.
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 ei…ther 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. (MORE)
First Step in repairing Terrazzo is to fix the holes with matching resin and Terrazzo chips. Also fill in any cracks with matching resin. Then sand down the repairs. The next step is to hone the floor with metal diamonds, usually 50 metal diamond followed by 100 metal diamonds. Then the resin diamon…ds are used 50,100,200,400,800 then polish with 5x powder. Rinse off and left over haze the buff. This will give a very high shine that will last for many years.

You can use strippers and or aggresively grind the surface. The matrix of the terrazzo is a resin and strippers will usually not affect it. When putting something on a surface it is always a good idea to try it in an incospicuous area to make sure it will not harm it. Grinding may be a job for a pro…fessional but if you have expierence then it is rather easy. (MORE)
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 little 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.....

Messy job. Involves solvents and lots of elbow grease. Check in at your closest home improvement store for a variety of methods, none of them fun.
\n. \nEach individual strip of hardwood flooring is nailed to the sub-flooring below it. \nYou're not going to be able to do that with a terrazzo floor. \nIf you attempt to glue plywood down to the floor first, it's going to end up buckling. \nThe temperature and humidity on one side of the plywood… will be different then the other because of the cement. \nIf you really want to do this, you're going to have to put a vapor barrier over the cement, \nbuild a deck over the vapor barrier, nail plywood to the deck, and then run the hardwood over that. \nIt's a lot of work, a big expense and the floor in that room is going to now be 3" higher then it was. \nThere are several kinds of laminated flooring systems that "float". \nThey just sit on top of the vapor barrier and they're under 1/2" thick. \nSome of them have real hardwood vineers and look just like traditional hardwood floors. \nYou might want to consider one of those. \nI cant believe you want to cover terrazzo, can't you just have it restored?

Look on the asphalt container for mention of a solvent or cleaner. -Use that first. If no mention, try hot soapy water on a small piece, then lacquer thinner.
As of 2014 there are only a few retail locations where one can buya terrazzo repair kit. These kits can be purchased at Home Depot,Lowe's, and local hardware stores.
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 carefully 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. (MORE)
Goof Off has more chance of working than anything. Rub it with this till it softens enough to peel off.
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 terrazzo better be pretty darn ugly before covering it. Terrazzo is one of the most exspensive and durable floorings money can b…y. As a rule well cared for terrazzo flooring adds value to any commercial or residential space. (MORE)
I scrape it off with a small, flat, metal trowel, then clean with Goo Gone.
Terrazzo is a type of flooring. In consists of stone chips set in mortar- when the mortar is cured, the stone is ground down and given a high polish, resulting in an incredibly durable floor. "The new airport has a beautiful blue terrazzo floor in the lobby."
No. unless you want your floors to buckle from the moisture. It is not recomended to install laminate flooring over terrazzo flooring. The moisuture buildup will ruin the wood planks.
Do you mean solid hardwood? You should not install 3/4" solid hardwood directly on top of terrazzo, or concrete or tile. Solid hardwood is supposed to be nailed into 3/4" plywood. Now theoretically, you might be able to add 3/4" plywood in, if you can actually get it into the terrazzo. It is poss…ible (but challenging) to add plywood into concrete using hilties, but it tends to be expensive and time consuming. Also, if you were to add plywood and solid hardwood, you would be raising your floor 1.5 inches. This may cause some height issues, especially for the doors (which might need to be shaved or replaced). If there is kitchen, this could cause height issues with appliances and/or cabinets. However, if you mean an engineered hardwood, it could be floated on top of the terrazzo. You put an underlayment underneath and then install the wood on top. If it is a clickable engineered wood, then you just click it in; if it isn't, then you would glue the joints together. (MORE)
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.
There are a number of dealers of Terrazzo flooring in the Sydney area of Australia. These include AMM Polishing, Western Terrazzo Restoration and Affordable Polishing.

Epoxy-based terrazzo can sometimes be affected by water-basedliquids and mild acids, but that would usually require a lot ofliquid constantly on the surface. Cement terrazzo is very resistantto liquid damage or discoloration. A lack of shine is more likely alayer of dried juice on the surface.
