This is the most detailed guide on how to restore terrazzo floors where we have discussed a few simple DIY steps.

During the Venetian era, mansions were constructed with terrazzo floors, an old style of flooring. From marble shards leftover from high-end jobs came the first terrazzo flooring makers.

This floor is created with one layer of floated concrete or clay on top of the marble fragments, forming a mosaic. This low-cost substitute for real marble can be used for a variety of surfaces, including floors, patios, countertops, and sidewalks.

Terrazzo flooring may now be created in a wide variety of hues because of the widespread usage of glass chips in this material. A grinder is used to sand down the floor after it has dried.

Then it is polished and sealed to keep the marble look. As with many other surfaces, terrazzo floors will require restoration at some point due to the high volume of traffic they receive over time.

Let us dive into the DIY process on how to restore terrazzo floors explained in detail in this article.

Steps On How To Restore Terrazzo Floors

Now that you know all the considerations about the floor; let’s directly move on to the restoration process. Here are steps that you can’t ignore on how to restore terrazzo floors properly.


A terrazzo floor must first be prepped before restoration can begin. Remove all of the terrazzo off the floor. Remove all of the room’s furniture and accessories at this point.

Do not forget to remove all of your old floor coverings, such as carpet and tile. Remove the adhesive by using a Dremel tool.

Tape the terrazzo-floor-touching walls and cover them with waterproof coating. It’s time to connect the hose attachment to the surface grinder that came with your rental. If not, apply a little bit of water to the entire space.

Understanding Problem

High-traffic areas must be restored to their original appearance. Nevertheless, not all damage is the same. It’s time to start figuring out how much harm has been done.

How severe is the damage? Can you see scratches all over the surface? As the most effective abrasive pad for use in the restoration process, this is an essential question that must be addressed.

For hundreds of years, terrazzo floors have been used in public places. Because of its durability in high traffic areas, managers must devise a restoration plan that includes maintenance, assessment of the damage, and long-term preservation.

To maintain a terrazzo floor’s year-round brilliance, it is simple to execute a safe and environmentally friendly strategy.

Grinding Of The Floor

Your terrazzo floor’s high gloss shines achieved by grinding, exactly like buffing, which also helps lighten any existing stains.

The correct diamond mechanical grind is required if you want to obtain color purity and a high gloss finish. In comparison, others choose to forgo this stage.

It’s recommended that you use a 400-pound grinder to smooth your terrazzo surface while revealing any previously hidden damage.

Then, using a finer-grit grinder, go over the complete terrazzo floor one more time until you’ve gotten the level of detail and sheen that you prefer.

Once the diamond grinding operation has been completed, you can try applying a poultice to check if any stains remain.

Patch For Cracks

It’s good to repair any terrazzo floor cracks and holes before polishing. Color-tinted epoxy can be used to match the marble chip’s color in your terrazzo.


After repairing any holes or cracks in your terrazzo floor, grind it down and refinish it. Oil stains and moisture damage can both be prevented by sealing the surface.

The terrazzo pores will be sealed off when you use a sealer. As a result, the floor will not be ruined by water seeping into it. On the other hand, Penetrative sealers enhance the color purity of your terrazzo floors.

Polish The Floor

After the terrazzo floor has been restored or repaired, the final step usually is to polish the floor. Recrystallization, polishing powder, or the method of diamond-polishing can all be used to achieve this end result.

Diamond polish is the most efficient of the three polishing techniques. High gloss can be achieved without creating a slick floor surface.

It’s alright to go with a less expensive option if you’re on a budget. The terrazzo floor only requires a light dusting of the powder, which may be worked into the surface with a soft cloth.

At least twice, use a higher-grit powder to repeat the polishing operation. Remember that polishing powder or recrystallization-finished or terrazzo floors usually need to be rebuffed every couple of years, just in case.

On the other hand, diamond-polished terrazzo floors generally retain their high-shine appearance before you need a rebuff.

Maintainance Tips

You have to maintain the floor so that you don’t have to perform the entire work frequently. Here are some tips on the maintenance process.

Daily Cleaning

Sweep & Dust Sheets capture up to 800% more dirt, dust, and sand than ordinary flat cotton dust mops or the professional sweeping dust cloth brand.

When you’re done, use a professional clean and shine cloth, which removes black spots and small scratches using only a low-speed scrubber. This lessens the need to burnish and, in some cases, eliminates it.

Clear Entryway

When it comes to nature, she may be a pain. Entrances should be kept dry and free of obstructions that could allow moisture to enter. The elements can damage a terrazzo floor, besides the risk of falls and slips.

Stop Debris And Moisture

Consider installing a floor mat as a facility manager. It might be challenging to keep the lobbies and entrances spotless because so much dirt and grime is tracked in.

What’s the answer? Matting for the front doorway. There are also wet area mat systems that reduce the risk of slipping and falling.

Using a mat system reduces the amount of mopping and vacuuming required while also protecting the terrazzo floor from wear and tear.
