Terrazzo Tiled Hallway Polished in South Wales

Terrazzo is a quite a bit different from the natural stone floors we most commonly work with. It’s a type of flooring material that was made popular by Venetian builders in Italy in the 1920s, but is ultimately descended from styles of design that date back hundreds of years. A typical Terrazzo floor consists of chips of marble or granite set in concrete and polished to result in a smooth surface.

This Terrazzo floor, installed in the hallway of a property in Bridgend, South Wales, was in relatively good physical condition, but it had clearly lost its shine due to the build-up of dirt and muck over the years. In fact, it was first installed in around 1940! The owner was keen to have it rejuvenated to its best possible condition, so they asked me to come in to see what I could do.

Cleaning and Burnishing a Dirty Terrazzo Tiled Floor

My first course of action was to apply Tile Doctor Pro Clean liberally across the floor and leave it to dwell for a short period. This is a high alkaline cleaner that is designed to deal with light to moderate soil build-up, and to strip away any old sealer remaining on the floor. I scrubbed the product in using a black pad fitted to a rotary machine and vacuumed up the resulting cleaning with a wet-vac machine.

Next, to restore the shine to the floor, I undertook a process known as burnishing, which involves the application of diamond encrusted polishing pads. We will typically start with a Coarse grit pad to level off any uneven areas of the floor and grind down any particularly stubborn marks and stains. Then, we gradually refine the polish on the floor using Medium and Fine grit pads. A small amount of water is used as lubrication with each pad.

After I had finished applying the first three pads in our four-pad system, I gave the floor a thorough rinse and left it to dry overnight.

I returned to the property the next day and immediately ran some damp tests to check for excess moisture issues, which one might expect with an old floor like this one. Thankfully, the floor proved dry – and I could finish the burnishing process with the fourth and final Very Fine diamond encrusted burnishing pad, which achieved a beautiful shine finish.

Finally, I sealed the floor with three coats of Tile Doctor Colour Grow, an impregnating sealer which provides robust protection and enhances the coloured patterns in the Terrazzo.

As you can see from the photos above, the floor is looking so much more colourful and bright after a deep clean, polish and a fresh seal. The customer was over the moon!

Old Terrazzo Restaurant Floor Fully Restored in North Wales

The Washington Hotel in Llandudno, North Wales, is a truly historic building and one of the enduring features on the promenade of the sea resort. This beautiful part of Wales was the holiday destination of choice for Lewis Carrol, the famed author of Alice in Wonderland, and you can see several statues of him in and around the town.

The Washington Hotel first opened in 1855, but was rebuilt in 1925 after being destroyed by a fire. The building most recently served as a nightclub, before it closed in 2012. Now, there is ongoing renovation work to turn it into a restaurant.

As part of this renovation work, we were asked to restore bring the old Terrazzo floor back to life, which was certainly worse for wear after nearly a century of use. It had been covered in carpet, as well as old vinyl tiles, and was very heavily soiled with dirt and ingrained muck. This area of floor would eventually act as the entrance to the restaurant and bar area, so it was important to get this right for the customer.

Burnishing a Terrazzo Tiled Floor

There were three areas we were asked to restore, covering 36 square meters in total:

• Circular foyer (27 square meters)
• Internal entrance area (2 square meters)
• External entrance stairs: (7 squares meters)

We started the restoration process with the application of a Very Coarse 50 grit diamond pad to tear away all the old carpet and vinyl resin, clearing the area to allow us to work directly on the Terrazzo tiles. With the tiles exposed, we discovered two large, long cracks in the base of the floor, so we filled these with a flexible floor grout. We chose to use this instead of a resin compound because resin isn’t very flexible, and if there is any movement the crack will become exposed again after six to 12 months. A flexible floor grout will move with the contractions and expansions of the base, and if the movement is not too extreme the flexible grout will not crack in the future.

We then continued through our system of diamond burnishing pads, applying the 100, 200, 400, 800, and 1500 grit pads with a small amount of water as lubricant. Once the floor was fully dry we applied the final 3000 grit pad, which is the finest of the pads and produces a very high quality polished effect on the stone.

Sealing a Terrazzo Tiled Floor

Once the floor had been polished, it needed to be sealed in order to protect it from dirt becoming ingrained into the pores of the stone. We did this using firstly two coats of Tile Doctor Colour Grow, which is our impregnating, colour-enhancing sealer. The sealer works by penetrating the pores of the stone to fill them and block trapped dirt and stains. We then left the floor to dry off fully overnight.

The next day, we returned to the building to apply a crystallization powder known as Tile Doctor Shine Powder, which further enhanced the shine we had built up on the floor and give it extra sealer protection.

The customer was exceptionally happy with our work, as the restoration of the Terrazzo tiled flooring is an essential part of the renovation project overall. We wish them all the best in the eventual opening of the new restaurant!

For aftercare, we recommended to the customer that the floor is maintained with Tile Doctor Stone Soap as this will not only clean the Terrazzo without damaging the sealer like many stronger cleaners, but also maintain its patina as well.
