The material can be manipulated throughout its production, making it ideal for design elements. Long-lasting dyes and stains can be added to the terrazzo as it is being made to create just the right golden hue or any shade that can be imagined. The epoxy coating can withstand years of hard use, but it may need to be repaired or resurfaced on occasion depending on the color and application. The durability of the tile makes terrazzo restoration an easy endeavor.


How to Repair Terrazzo Flooring

The variegated coloring and classic style of the tile can make terrazzo repair seem intimidating. If a fine line has begun to spread on the surface of the terrazzo flooring, then you have a growing issue that needs to be addressed. If left unattended, the little lines can become big problems that can cause damage to the integrity of the terrazzo flooring.


For little jobs, place a small amount of epoxy and any coloring to match the terrazzo, if needed, to a piece of cardboard. Thoroughly mix the epoxy with a toothpick and gently apply it to the fine lines. Let it dry for at least 24 hours before allowing people to walk over the area.

For larger repairs, clean out the crack and use paint stripper to remove the sealant surrounding the area. Use a high-gloss, oil-based paint that is tinted to match the terrazzo. Carefully apply it to the cracks to cover them. Apply a sealant to blend the repair into the rest of the terrazzo flooring.


You can use cement grout to fix problems that appear on Portland cement-based terrazzo flooring. This can take a lot more work. The repair area needs to be sanded with a fine-grit paper to prepare it. Mix grout to fill the crack, adding any dyes to get the color needed. Apply the grout to the area with a trowel. Let it dry overnight before sanding down to be level with the terrazzo flooring. Use 80-grit sandpaper followed by 100- or 120-grit sandpaper to achieve the desired finish. Apply a sealant to the repaired area.


If the crack is wide or deep, a professional may be needed not only repair visible damage but to find the root of the problems in order to prevent future issues from popping up on the pristine surface of the terrazzo flooring.

Terrazzo Doorsteps

Terrazzo steps get the brunt of abuse from guests and residents as they come and go from the home. Terrazzo is hardy, but it can handle only so much.
