Terrazzo's origins. The word "terrazzo" comes from the Italian word for "terrace." It's a mosaic material that was born out of frugality; 15th-century Venetian marbleworkers created it because they were unable to afford marble for their own terraces. Settling odd-size discarded marble pieces from paying jobs in clay, they created attractive patios or terraces for themselves.

At first the surface was rough and a little hard underfoot. But the artisans soon realized that if they rubbed the marble pieces with a stone they could get a smoother, more inviting surface to walk on. These days glass, granite and quartz are used as well as marble to create different effects.

The process involved in creating terrazzo flooring now is a little different to that of the craftsmen in the 15th century. And a few options are available, so having a detailed discussion with an expert terrazzo company is recommended.

Modern terrazzo. Until the 1970s, terrazzo installation involved onsite pouring of a cement base. Once that was dry, a layer of sandy cement was added, then a layer of the colored chip mixture was applied to the wet cement. A weighted roller was then run over the surface.

Today installers use thinset terrazzo, a mix of epoxy resin and colored chips. Poured onto the slab in a layer that's 1/4 to 3/8 of an inch thick, it is quicker to install. Thinset terrazzo also offers a wider range of color choices, is lighter in weight, has a impervious finish and cracks less. The only downside to the epoxy resin base is that it can be used only for interiors, as it will peel and lose its color outside.

Once the surface is dry, a grinder is used. Any holes are filled and troweled for a smooth finish. Then the surface is cleaned, polished and sealed. This gives the terrazzo its lovely, shiny finish.

The fantastic condition of the original terrazzo flooring in this renovated 1950s contemporary house in the U.S. Northwest confirms terrazzo's longevity.

Precast terrazzo. Precast terrazzo is a made-to-measure product. Almost anything can be formed with terrazzo: countertops, wall panels, sinks, furniture. An array of colors and finishes is available.

As with all surfaces, caring for your terrazzo is important. It does not need shielding from wear, but it needs shielding from spill absorption and stains. Quality terrazzo will be sealed, but this sealant is not a long-lasting barrier against stains. All spills should be wiped up right away. It's best not to cut on it, as it will scratch. Also, placing hot products directly on the top may cause cracking.

Terrazzo costs more than granite or marble. Professional installation is recommended, so that adds to the cost, too. On the plus side, it's durable and long lasting.

In this kitchen the green in the terrazzo pops as well as harmonizes with the tile backsplash. And it looks lovely against the neutral cabinetry.

Terrazzo finishes. In the mid-1970s terrazzo fell out of fashion, but it has made a comeback in many different applications. Creating terrazzo furniture is a bespoke art that appeals to a contemporary aesthetic. When terrazzo is used in a three-dimensional way, it can make for beautiful, functional furniture.

Polished, honed and shot-blasted finishes are all available with terrazzo. A honed finish gives it a flat, or matte, look. The color is slightly duller than that of a polished finish and has a less formal look. To achieve the shot-blasted look, the terrazzo is blasted under high pressure with small steel beads. The top layer of mortar is also removed so the stones show up more, which has the added benefit of providing more protection against slippage when it's wet.

Terrazzo in the bathroom. Terrazzo sinks are a great alternative to the standard, ceramic bathroom vanity sink.

Designed and precast by artisans, sinks and baths made with terrazzo should be sealed carefully so that the water does not penetrate the surface. A water or solvent-based impregnator sealer needs to be applied immediately after honing or polishing the terrazzo. Check with the manufacturer that the right sealer has been applied, especially if you purchase a vessel that will hold water on a regular basis.

A terrazzo trough sink like this one, built by The Brooklyn Home Company, would be a focal point in any bathroom.

Lanie Brown This modern terrazzo does not look anything like the original terrazzo I see in 70s homes. I was hoping for ideas on how to work with the original material to update entryways and bathrooms.

Paul D'Amico - Period Design Terrazzo can be combined with stone tiles or mosaics or anything. Its extremely versatile. I will post examples when I return from my Holiday.

3angela When we lived in Mexico, our 16th century house had had terrazzo floors, which had been installed in the 20s. I loved those floors. They were beautiful and very easily kept clean.

maeeast I LOVE my terrazzo floor. My house was built in 1964 in Florida. The entire main floor is terrazzo. (The upstairs is hardwood.) It is fabulous. No thresholds means universal design. And when I renovated the kitchen, I didn't have to worry about the floor "matching" because the entire slab is terrazzo. I can knock walls down and move them anywhere without worrying about mismatched floor coverings.
It's easy to keep clean and cool on bare feet. And added benefit in Florida, terrazzo is great in the constant fight against mold, mildew, and bugs.
The major downside is price. It's currently running $75/sq ft to install, and it costs about $5/sq ft to "tune up" -- the terrazzo equivalent of steam cleaning carpets.

Paul D'Amico - Period Design Thank you Gabrielle for bringing the terrazzo topic up. I have posted photos of terrazzo floors made in Italy. I wanted to show the patterned type because usually people have only seen plain ones or non patterned ones. They also have them combined with mosaic and marble slabs. I'm sure that I have photos I took in Rome at Palazzo Corsini - a Renaissance Palace. I will post as soon as I can. There is a lot more to say about the various techniques and types. They are more suited for warm climates, though UFH might make them adaptable to cooler parts of the globe. Watch this space.

midmodfan I always loved terrazzo floors. Hope that one day we'll own a modest modern home in Southern Florida with original terrazzo floors that nobody ever tiled over!

cbailey60 Help. We have one of those 60s era terrazzo floors in our kitchen/breakfast area and it needs "tuning up" but we live in a rural area and have been unable to find anyone to do it. The floor is worn under the cabinets and is almost impossible to completely clean. Otherwise it is in good shape except for that issue and a yellowish appearance. Is there a do it yourself method we could use?

aidabear Check out American Terrazzo They're in TX and could price you restoration,patching, and Venetian designs Most reputable NTMA members can match a 100 year old floor pretty close so long as marble/misc aggregates are still quarried

bikespaces 1. I doubt that terrazzo floors put down today using "modern methods" will last anywhere near as well or as long as the stuff that was being poured even as late as the sixties and seventies. So, showing us a floor poured in 1964 to indicate how long newer terrazzo will last is disingenuous, at best. In any event, the picture currently showing looks to be wood floors, not terrazzo.

2. If you want to see terrazzo floors, many US public buildings built before 1980 have highly decorated terrazzo floors in high traffic lobby areas (marble was the previous public building choice, but marble is easily destroyed by stilletto heels, which came into widespread use after WWII). Because the floors cover huge expanses, it was cheaper to lay down than anything else, and is (relatively) cheap to maintain (ever wonder why the floors in your old office building's lobby get polished once a month or more?). In a house, with walls every ten to thirty feet, I can't even IMAGINE how much more it would cost to clean.

3. I cannot imagine a good reason to put terrazzo anywhere where it will get hard wear (that is, I suppose you could use it on walls). Even sealed, it can't take spills. And TUBS or SINKS?!!! What a waste, unless you have ridiculous amounts of money to burn. A shotblasted finish, outdoors under patio cover would be okay, I guess, so long as you know you aren't going to keep the house for thirty years, and have to replace/repair it.

4. I have posted elsewhere about how hard concrete (the base of all aggregate floors) is on your feet, legs, and joints.

littlemjs I recently bought a house built in 1965 in central Florida. It has terrazzo floors throughout. The owner had covered up the bedrooms with wall to wall carpeting....which is really a no no here in hot and humid Florida. We pulled up the carpeting and underneath was the beautiful terrazzo floor. We had a company in that took 5 days to clean and polish the floor in the whole house (before we moved any furniture in) and the floors look fantastic. Not a crack anywhere. The floors are easy to clean and never show the dirt. I would never cover these up with any other type of flooring. Whenever anyone comes to visit...they are amazed at the floors and really amazed when I tell them they are essentially "polished concrete"! You figure they've have held up for almost 50 years and still going strong!
