Deep Cleaning Dirty Terracotta Tiled Kitchen Floor in Moretonhampstead

Earlier this year I was called to the Dartmoor town of Moretonhampstead in order to take a look at a large Terracotta tiled kitchen/dining room which the owners had ‘lived with’ for over a decade but were finding it harder and harder to keep clean. Upon arrival, I could see that any sealer that had been used previously was well beyond its best and the floor was holding in the dirt and grime because of how porous unsealed terracotta is.

I conducted a test on a small area of the floor which not only helped me to identify the most suitable product to clean the floor with but also to show the customer how much of an impact a professional clean and seal of a floor is likely to have. The first product I tried was Tile Doctor Pro-Clean which although cleaned the tiles very well I could tell was going to be a problem when it came to rinsing because the floor was absorbing it almost as quickly as I was able to put it down! My solution came in the form of Tile Doctor Oxy-Gel which is a very similar product to Pro-Clean and is a very powerful stripper/degreaser but has the added benefit of being in gel form, so it sits on the tiles rather than becomes absorbed into them. It is also a very good option for riven stone, uneven tiles or undulating floors because unlike a liquid it will not run off the high spots.

The clients were thrilled with the test area and couldn’t believe how much lighter the tiles were and as soon as I sent them my quote they booked me in at my next availability.

When I returned to the property my first task was to protect the woodwork from splashing by dressing the skirting boards and kitchen plinths in a blue plastic covering. I then set to work applying Oxy-Gel to the tiles and allowing it to dwell for about five minutes before scrubbing it in with a stiff bristled brush fitted to a rotary buffer.

The scrubbing action released the dirt form the Terracotta and I was then able to extract it from the floor using a wet vacuum. I worked methodically in small areas at a time and when the whole floor was done it was given a thorough rinse to remove any trace of cleaning products from the floor. I also checked the floor carefully and spot treated any stubborn staining and used the wet vacuum to get the floor as dry as possible before leaving for the day.

Sealing Terracotta Tiles

After I was satisfied that the tiles were all clean I then needed to wait for the floor to dry before I could seal. As I mentioned these tiles were very porous and so took longer than usual to dry out but once the moisture levels were at an acceptable level I returned to finish the job.

Once terracotta has been stripped it can reveal historic damage such as acid stains or from inappropriate cleaning products which look like lighter patches on the tiles. Upon my return I spent a while improving any areas like this by using diamond encrusted burnishing pads to resurface the tiles. In general, it is not recommended on terracotta because you lose the natural texture of the tiles and create a smooth finish but in this instance the customer decided that this was preferable to the stains remaining visible.

After both the customer and I were happy with the condition of the tiles I began to seal the floor with Tile Doctor Seal and Go, an acrylic based sealer which would give the tiles a slightly glazed or freshly mopped appearance. Because of the porosity of this particular batch of terracotta tile it took eleven coats before the floor was fully sealed!

The customer was very happy, and the tiles lit the room up, transforming it.

Centuries Old Limestone Flagstones Resurfaced and Restored in South Milton

South Milton is a small, but very old town of about 400 inhabitants in South Devon. The village has been there for at least 1,000 years and is known for the nearby National Trust beach area of South Milton Sands.

I recently visited the area to visited a customer who had discovered a Limestone tiled floor that had been hidden under carpet for around twenty years. The floor was several centuries old – as is the property itself – and it was suffering from a problem known as flaking or shaling, which is when the top layer of the stone starts to flake off.

The customer had already made the decision to remove the carpet and underlay because they wanted to reinstate some character and original features to their dining room! The floor was very dry and dusty and had the imprint of the underlay firmly embedded in some areas. As a result, the floor appeared cracked and damaged (see the photo below) and was in dire need of restoration.

A test was conducted using both chemicals and diamond-enhanced abrasive pads to ascertain the most appropriate restoration method; although the diamond pads are the only real option to address the shaling the chemicals could have also been used in the cleaning of the floor. The test showed that the diamond pads were the most effective solution for the floor and a quote was produced which as accepted.

Milling a Damaged Limestone Tiled Floor

With the state the floor was in, I needed to use a process called milling, which involves using Very Coarse diamond encrusted pads fitted to a heavy rotary scrubbing machine to cut back the damaged layer of stone to unveil a fresh surface. The floor was suffering from mild lippage and undulation problems, and the milling would be able to resolve these problems too.

Lippage occurs when the surface of the floor becomes uneven and the tiles are not level with one another, and this can be quite hazardous. Undulation is when the floor gets a wave-like appearance.

After cutting the floor back with a 50 and 100 grit coarse milling pads to expose the new surface, I gradually smoothed the surface with finer pads up to 400 grit to close the pores in the stone.

The floor was then given a thorough rinse which ensured it was clear of all dirt and soil that had been generated, even the imprint from the underlay had been effectively removed.

Sealing a Limestone Tiled Floor

After cleaning the floor was left to dry for two days to ensure it would be fully dry before our return to seal the floor. To seal I used a colour-enhancing sealer called Colour Grow which impregnates into the pores of the stone, lifting the colours and protecting the stone from within. Colour Grow is suitable for use on a variety of natural stone, including Flagstones, Flamed Granite, Limestone, Marble, Quarry Tile, Sandstone, Slate, Travertine as well as Victorian tiles.

You can see the complete transformation of the Limestone tiled floor in the photo below.

The difference made is quite remarkable! The customer had believed the tiles to be unsalvageable, and so she was over the moon with the outcome.
