Due to limited site access, we utilized specialized, smaller equipment to complete the work efficiently without disrupting surrounding areas. Terrazzo polishing is similar to polished concrete, but it requires careful modifications to account for the unique terrazzo properties, particularly the additional heat generated by terrazzo friction. Throughout the process, we applied a concrete hardener and a polished concrete guard to strengthen and protect the surface.

To address the uneven and damaged areas, we installed a polishable overlay at the threshold and used clear grout to fill small holes and pores across the floor, creating a smooth, uniform appearance. The terrazzo was polished to a 400-grit finish. While the repairs remain visible upon close inspection, they blend significantly better with the surrounding floor, resulting in a cleaner, more cohesive look that aligns with the refreshed bathroom space.

Below is a detailed view of the polishable overlay installed at the door threshold to create a smooth, even finish.

The TerrazzoShine 5-Step Process

First, we’ll perform a thorough, inspection of your floor to determine the steps needed to restore the terrazzo to its natural luster and character. You’ll receive a written estimate for the restoration.

On your approval, MJA’s TerrazzoShine experts will begin the 5-step terrazzo restoration process:

Step 1: Stripping

• Remove all waxes and residue

Step 2: Repair

• Repair chips.
• Fill nail holes from old carpet tack strips, if any.
• Hand-chisel existing gouges to allow refilling with blended, matching marble chips and concrete colors.
• Remove surface stains.

Step 3: Grinding

• MJA TerrazzoShine craftsmen will use special diamond grinding disks to remove scratches and uneven surfaces.
• The grinding process proceeds with a series of increasingly fine diamonds until the floor is smooth and free of virtually all surface imperfections.

Step 4: Polishing

• When the terrazzo surface has been restored to a smooth, light-reflective condition, we begin polishing with the TerrazzoShine polishing agent, specially formulated for terrazzo restoration.
• If possible, penetration stains will be removed entirely. Stains that cannot be removed without compromising structural integrity of the floor  will be lighter and less noticeable. (Even those stains will honor the history and character of your floor.)
• Polishing continues until the floor is restored to a glass-like finish, allowing it to reflect its natural, old-world beauty.

Step 5: Sealing

• TerrazzoShine’s environmentally friendly thermal sealer is burnished into to your newly-restored floor. This sealer will help maintain the floor’s shine with easy, low-cost maintenance.

The MJA Company’s environmentally-friendly TerrazzoShine thermal sealing process eliminates the need for costly, time-consuming stripping and waxing. You’ll save time and money with TerrazzoShine.
