In this edition of Terrazzo Techniques, we will examine renovating restroom areas to install new epoxy terrazzo floors or refinishing existing terrazzo floors. Please watch the terrazzo installation video below, with images provided by one of our project managers. It showcases one of Doyle Dickerson Terrazzo’s recent restroom renovations.

Modern restroom designs are focusing on creating an inviting and relaxing experience for occupants. To achieve this objective, public restrooms must be attractive, durable and easy to maintain.

Public restrooms are used heavily around the clock; therefore, it is essential to include a low maintenance flooring surface such as epoxy terrazzo that is easy to clean and keeps the space looking neat and tidy. With epoxy terrazzo’s design aesthetics, the flooring material can combine with cost-effective fixtures and accessories to create a warm-look environment. Other elements that can elevate the restroom design include good lighting and touch-free technology.

One alarming issue associated with older restroom designs is the growth of mold. Mold can eventually enter the interior of materials, leaving behind foul odors. As a result, the space declines in overall air quality. Epoxy terrazzo is a non-porous flooring system that is completely antimicrobial, preventing bacteria to multiple and spread to other areas of the room.  Another benefit of adding epoxy terrazzo to a public restroom design is its low content of VOCs, promoting higher indoor air quality.

Adding Epoxy Terrazzo Flooring

Before adding an epoxy terrazzo floor to any area, inspect the space. In the video, one of the imposing challenges was adding a terrazzo cove base around toilet pipes. This is just some of the obstacles that you may face when installing terrazzo in a restroom area. For the flooring surface, contact your local terrazzo contractor to learn more about a moisture mitigation system. Because restrooms are susceptible to water spillage, a moisture mitigation system will be beneficial during the lifetime of the floor. A moisture mitigation system will create a barrier against moisture vapor transmissions.

Once the floor layout is finalized, terrazzo installers can begin pouring the terrazzo mix. The terrazzo installers will grind and polish the terrazzo surface, finishing the floor with a sealer.

 

Refinishing Terrazzo Floors

It is recommended to clean terrazzo floors with a damp mop as needed. However, it is also recommended to reapply the sealer of a terrazzo floor.

When periodic sealing is needed, use a chemical stripper to remove the existing sealer and any finished coats from the surface. Ask your local terrazzo contractor for a suggested chemical stripper to use. Also follow the manufacturer’s written instructions on how to apply the chemical stripper.

During this process, you want to make sure you keep the surface wet while the material reacts to the floor in order to remove the existing sealer.

After the chemical stripper has been applied and settled, an installer can use either a floor buffer with a white pad, a damp mop, or an auto scrubber to go over the terrazzo surface. Once the surface has been cleaned and dried, you may notice a difference in the terrazzo floor. Because the sealer has been removed, you will notice that the floor has lost its sheen and will have more a dull appearance.

Once the sealer has been removed, go over the terrazzo surface with a damp mop using clean water. Wait until the surface is completely dry before applying the new sealer.

Use a solvent-based sealer, applying in multiple coats with a microfiber applicator (two coats likely for restroom flooring due to the porosity of the surface).  Once the sealer is dry, the terrazzo surface will achieve a glossy finish.

By applying a sealer occasionally, you can protect the terrazzo floor from any acidic staining, especially around toilet areas.
