Old Terrazzo Floor Cleaned and Polished in Birmingham

This post follows on from the Victorian Tiled floor article I published earlier, if you recall I was asked to restore a Victorian Tiled Hallway at a house in Dudley and there was a section that was Terrazzo, so I thought it would make sense to write about this separately as the cleaning method is different.

Both period floors were original, having been installed when the house was built over 100 years prior and whilst Victorian tiles are quite the norm in these properties it’s quite unusual to find Terrazzo as this was mostly used in large public buildings.

There was a crack running across the floor which is quite a common problem with Terrazzo as it’s laid in one piece like concrete and any movement in the ground will cause stress leading to a crack. Unfortunately, the only way to resolve this properly is to have a Terrazzo expert relay that section of the floor which would prove expensive.

Terrazzo is the by-product of broken pieces of stone, often Marble, Limestone and Granite, which rather than being wasted are set into to a cement screed and poured onto the floor, then once the screed is set it is grinded to a polish.

Cleaning Original Victorian and Terrazzo Tiles

The polish on Terrazzo will eventually wear down with use and to restore the appearance it needs to be burnished with a series of pads with different grits from coarse to fine.

So, to start the renovation I gave it a general clean with Tile Doctor Pro-Clean mainly to remove any grit before burnishing. Next, the Terrazzo tiles were cleaned using a coarse 400 grit pad fitted to a rotary machine and lubricated with water. This process removes dirt and any coatings such as sealers and the floor needs to be rinsed afterwards to remove the slurry that is generated.

Then to build back the polished appearance, the floor is burnished with an 800 grit medium pad followed by a 1500 grit fine pad. Less water is used this time, but you do need to rinse the floor again after each pad to remove any slurry gets generated during the process. Once this was done the floor was dried with a wet vacuum and left to dry off fully overnight.

The next day, I returned to the property and started with a damp test to make sure the floor was dry and ready for sealing. The floor was dry so I finished the Burnishing process by applying the last pad in the set which is a 3,000 grit (very fine) pad that adds the final polish to the Terrazzo.
To protect the floor from staining and dirt becoming ingrained in the pores of Terrazzo it was then sealed with two coats of Tile Doctor Colour Grow which is a colour enhancing impregnating sealer that protects from within. Once the sealer had dried the floor was buffed with a white pad.

The floor looked a lot cleaner and shiner at the end and the customer was very happy with the transformation.

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.
