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 Floor Restoration Mablethorpe

Renovating Terracotta Floor Tiles in Mablethorpe

Details below of a Terracotta Tiled floor that was installed in the Kitchen, Hallway and WC of a house in Mablethorpe. You can see from the photographs below that the floor was not looking its best having been splashed with paint from decorating and overdue a deep clean and seal.

Terracotta Floor Before Restoration Mablethorpe

Terracotta tiles are very porous and need to be sealed to prevent dirt from becoming ingrained in the tile as once that happens, they become very difficult to keep clean and just look permanently dirty. Unfortunately, sealers wear off with use and so overtime dirt starts to become lodged in the tiles. Another problem we find is the premature degradation of the sealer due to the use of bleach-based supermarket floor cleaning products that are simply too strong for use on a sealed floor.

Having surveyed the floor I could see straight away that the tiles needed a deep clean to remove the ingrained dirt and deal with the paint spots, then resealing with a durable product that will enhance the look of the floor and importantly protect the Terracotta. I worked out a quote for the renovation work which my client was happy to accept and a date was set for my return.

Deep Cleaning Terracotta Floor Tiles

To get the tiles clean we applied a strong dilution of Tile Doctor Pro-Clean mixed 50/50 with Nanotech Ultra Clean which combines well to produce a heavy-duty alkaline cleaner/coatings stripper. This combination is ideal for working with difficult floors and for best results I spray the solution onto the tile and grout and leave it soak in for ten to twenty minutes. Long dwell times give the product more time to work breaking down the dirt and softening up the paint.

The next step was to work the products into the floor using a black scrubbing pad fitted to a rotary machine running at a slow speed. Once done the resultant slurry was rinsed off with water and then extracted with a wet vacuum. The floor was inspected and any stubborn staining was spot treated using the same process until I was completely happy the floor was clean.

The floor was still quite wet at this stage with small puddles of water forming in the dips of the uneven floor; the wet vacuum took care of most of this but the floor was still too damp for sealing so I left a couple of air blowers to assist with the drying of the floor and returned two days later to start the sealing.

Sealing Terracotta Floor Tiles

When I returned the floor was mainly dry but there were a couple of damp spots which I took care of with a heat gun. Tile Doctor Seal and Go was used to seal the floor; Terracotta can be very porous so eight coats were required to completely seal the floor so it was some time before it was finished.

When finished, I gave the customer instructions on how to maintain the floor using Tile Doctor Neutral Clean which is a mild but effective Tile and Grout cleaner. He was over the moon with the result and said that it had far exceeded his expectations which is always nice to hear.
