Terracotta Tile Cleaning

Welcome to my Work History archive where you will find detailed examples of the cleaning and renovation of Terracotta tiles carried out in Dorset

Cleaning and Renovating Terracotta Tiles

Terracotta tiles have been around in certain parts of the world for over two millennia, in fact the word Terracotta means burned earth. The ancient Romans used a variety of terracotta tiles in their villas and palaces for many centuries. Terracotta tiles are thicker than most modern tiles giving them strength and durability.

The one big downside to Terracotta is the fact that it has no glaze on the surface and being very porous can soon pick up and store muck and dirt very quickly. If you have ever owned a Terracotta floor before you will be able to relate to this problem however the answer is to ensure you have the correct sealer in place.

Traditionally Wax was used to protect terracotta tiles however with the advent of modern purpose made sealers we don’t recommend it. Not only is it troublesome to remove but it scratches easily and we have seen situations in kitchens where dirt and oil trapped in the wax turns black and becomes very unsightly.

For sealing Terracotta we actually recommend Tile Doctor Seal and Go which works well on clay tiles such as Terracotta and is also water based so doesn’t give off a smell as it dries. When applying a sealer always make sure the floor is dry first as applying a sealer to a damp floor can lead to inconsistent results. Because of this we typically clean and seal Terracotta floors over two days so we can clean on day one and then apply the sealer on day two having let the floor dry off overnight.

Below you will find detailed examples of work we have carried out in the past, it should give you some idea of what’s involved and what can be achieved with the right techniques and products.


Terracotta Tiles Before After Deep Cleaning and Sealing Poole

Terracotta Tile and Grout Deep Cleaned in Poole

The photographs below are of Terracotta tiled floor at a house in the coastal town of Poole, Dorset that had not been professionally clean in some time and having seen years of wear and tear from the active family who live there was not looking its best.

The Terracotta had previously been treated with Wax which had now pretty much been worn off and the grout had gone dark with the dirt. We often find wax being used traditionally as a coating on Terracotta however a lot of science has gone into developing sealers in the last twenty years that do a much better job so Wax is not something we could recommend these days.

After surveying the floor and running several tests I was happy what was left of the wax could be removed and provided the customer with a quote for stripping the floor and resealing. The quote was accepted, and we arranged a date to return and carry out the work.

The floor was covered in a strong dilution of Tile Doctor Pro-Clean and this was left to dwell on the floor to allow it to soak into the tile and get to work on the dirt and breakdown the dirt and what was left of the wax. The solution was then worked into the tile and grout using a heavy 17″ rotary scrubbing machine fitted with a black scrubbing pad and then rinsed off using a high-pressure tool that also extracts the soil at the same time.

The grout was cleaned using more Pro-Clean and a stiff brush that was run along the grout lines. After rinsing and extracting again the floor was inspected to look for any outstanding issues. This highlighted several areas where Wax residue was still present on the tile which were spot treated using a new tile product called Tiled Doctor Wax Away which as its name suggests is designed for the purpose.

After another rinse and extraction, the floor was inspected again and this time happy with the floor it was left to dry off fully overnight with the assistance of an air mover.

Returning the next day, the floor was checked first with a damp meter to ensure it was dry and ready for sealing. The moisture readings were all good, so I set about sealing the Terracotta using three coats of Tile Doctor Seal and Go which is a water-based sealer that adds a robust and deep finish to the tiles. This can take some time to apply as you have to wait thirty minutes to allow the first coat to dry before applying the next.

I’m not sure the photographs do it justice, but the homeowners were “over the moon” with the difference in the floor and regretted leaving it so long before calling us in.

Before and After Sealing

Cleaning Terracotta Tiles Marked With Dirty Boot Prints

I had a rather long conversation with this worried terracotta flooring customer in Weymouth. This was a new installation of around 30 m2 of terracotta tiles. The tiler had laid the tiles and was in the process of sealing with a rather nasty rubber based yellow coloured sealer when his assistant walked through from outside with dirty boots. Being a very absorbent tile the dirty prints penetrated into the tiles within the sealer leaving lovely dirty chevrons all over the new floor.

To rectify this the tiler tried first of all with Nitromors and then with Gripex paint and glue strippers. Using these on any tile is not a good idea but on terracotta due to porosity all it was sink in and remain there along with the foot print. So at this point the tiler decided to try angle grinding one of the tiles which eventually he did manage to take out one of the prints although damaging the integrity of the tile. After visiting a tillers forum he was wrongly advised to sand the tiles with an industrial sander so he hired a sander for a day and set about sanding the tile back. After spending a fortune on sandpaper that just got gunked up with rubber sealer and a days of labour he had managed to sand around 5sqm and cover the whole house with orange dust…

This was when he said ‘ok enough is enough just don’t pay me for the tiling’ and walked off the job!

I spent two days stripping the sealer out with Tile Doctor Remove and Go and cleaning with Tile Doctor Pro-Clean assisted with a rotary machine fitted with a scrubbing pad in order to remove both the sealer and the dirty foot prints. After a hot pressure wash to clear the pores and remove any remaining chemical from the floor we left it to dry for a week.

Sealing Terracotta Tiles

We sealed the Terracotta Tiles with Tile Doctor Seal and Go which is a low sheen water based sealer recommended for Terracotta floors. Terracotta is quite porous and in this case the tiles required a lot of sealer where tops had been sanded off and in the end it took 12 coats before if was fully sealed.

The results were outstanding, you wouldn’t know that there had been any damage at all and the customer was very happy, not only that the job cost less than what was due to the tiler.
