How to Do Basic Terrazzo Repairs


This adhesive will NOT cure at low temperatures, at or below freezing. Terrazzo Epoxy should be stored at room temperature before dispensing.


The surface must be clean and dry. Remove dust, laitance, grease, curing compounds, waxes, foreign particles, disintegrated or soft base material and any previously applied potentially incompatible coatings.


Coverage is approximately 6 to 7 sf per gallon at ½ inch depth. For larger jobs please contact us for available options.


If matching any color other than white, you will need the Bonstone Liquid Tints to match the desired color of the matrix. You will need to achieve the desired color match before adding any aggregate or hardener.

For the aggregate, you will choose the aggregate to attain the appropriate match

  • Step 1) Now that you have your color match you are ready to add the hardener. The hardener is added using a ratio of 5 parts color matched epoxy A to 1 part hardener B. The hardener allows for a long working time, approximately
  • Step 2) Mix 30 to 35 lbs of chosen aggregate for each gallon of color matched epoxy. NOTE: Blend the aggregate based on the percentage of aggregate you see in your samples.
  • Step 3) Mix 4 to 5 pounds of the marble dust for each gallon of epoxy. The desired consistency should be that of peanut butter. You can use up to 6 pounds per gallon of epoxy of the marble dust if needed to get that consistency.
  • Step 4) You are not ready to trowel into repair area. The mix will harden overnight and will be ready for the first grinding cut the next day.
  • Step 5) After first cut, continue the process up to 120 grit of abrasives. At this point, you will need to do a grouting application to fill pinholes or voids created from grinding. Using leftover or additional epoxy mix and marble dust to make your grout. Again, using the 5 to 1 ratio of epoxy A to hardener B to mix grout. Pour this mix over area, then broadcast a couple handfuls of the marble dust over mix. Trowel this mixture, pushing the grout into the pinholes. You want to remove as much of the grout mixture as possible during this process leaving it only in the voids or holes. Be careful not to leave a lot on the surface as it will hardened and require more steps to remove.
  • Step 6) Continue with the honing process through the next grits of abrasive to achieve the desired finish.

Terrazzo Repair FAQs

Can you epoxy over terrazzo?

Yes, epoxy terrazzo can be applied over existing terrazzo systems. This is advantageous for renovation projects or instances where a change in the flooring system is desired.

Before the application of epoxy terrazzo, it is crucial to ensure that the existing surface is thoroughly cleaned, and moisture levels are checked. This process prepares the foundation for the new epoxy terrazzo application, promoting adhesion and a successful installation.

How do you fill gaps in terrazzo?

Filling gaps in terrazzo involves a similar process to repairing holes. The cause of the gaps should be identified, and the appropriate binder, typically epoxy resin, should be chosen. The repair mixture is prepared with suitable aggregates and binders, ensuring the right consistency.

Once gaps are filled with epoxy, curing, grinding, and polishing are essential steps to achieve a uniform surface that seamlessly blends with the rest of the terrazzo floor.

Can terrazzo be restored?

Terrazzo can indeed be restored through a careful and systematic process. The restoration typically involves removing debris and substances, repairing any holes or cracks, and polishing the surface to its former shine.

The steps include investigating the cause of any issues, selecting the appropriate binder and aggregates for repairs, and allowing sufficient curing time before grinding and polishing. Professional assistance is recommended for more complex repairs, ensuring a thorough and effective restoration process.
