Renovating a Terrazzo Hallway Floor in Doncaster

We were working on a Victorian tiled floor at a property in Doncaster and were approached by a neighbour asking if we would look at their Terrazzo hallway to see if anything could be done with it. This often happens, people see our van and come and see what it is we do. Once we have had a chat it often leads to more work.

The neighbour had tried everything to make their unusual floor look more presentable even resorting to wire wool and a vast selection of cleaning products. I could see immediately that any sealer that was once present had long since worn off allowing dirt to become trapped in the pores of the Terrazzo. It would need a deep clean and polish to get it looking good again and so I reassured them and arranged to return in a few weeks to do the work. We see a variety of floor types in this job and each one presents a different challenge.

Deep Cleaning a Terrazzo Tiled Hallway Floor

We started by taping up the surrounding areas, skirting boards and doors to ensure they were protected. A strong dilution of Tile Doctor Pro-Clean was sprayed onto the Terrazzo and allowed to soak in for ten minutes so it could breakdown and soften the decades of dirt that had been ground into the floor. This is a multi-purpose high-alkaline cleaner, stripper and degreaser. It can be diluted to suit the requirement and it is a very effective cleaner that removes grease, mildew and algae from areas that have been neglected or subjected to heavy use.

With the Pro-Clean still in place the Terrazzo was then honed and polished using a set of Tile Doctor 17in diamond encrusted burnishing pads starting with a coarse 400-grit. This coarse pad removed dirt and old sealers from the stone, its applied with water to lubricate the process and it wasn’t long before this turned into a dark slurry. The floor was then rinsed with more water and the slurry extracted with a wet vacuum. This process was repeated with the 800, 1500 and finally the 3000-grit pad which really brings up the appearance of the stone. The floor was then left to dry off overnight.

Returning the following day, I first checked the floor was dry using the moisture meter. Satisfied that all was in order I moved on to sealing, this would ensure the floor was protected and would help to prevent the built up they had experienced.

We sealed the lighter areas with an impregnating sealer called Tile Doctor Ultra Seal, this is a no-sheen, natural-look, solvent-based penetrating sealer which is formulated to provide maximum stain protection. To restore the colour and add protection to the black border Tile Doctor Stone Oil was applied.

The floors appearance was massively improved, and the client was delighted and very pleased that they had bumped into me. For aftercare I recommended the use of Tile Doctor Stone Soap which is designed for the regulate cleaning of sealed and polished floors.

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.
