Limestone Floor Cleaning and Polishing Bromley

Tumbled Limestone Floor Cleaned, Polished and Sealed in Bromley

I get called to renovate this Tumbled Limestone tiled floor at a property in Bromley every few years. The sealer does a good job of protecting the stone, but it does wear off with use and the natural crevices in the Travertine attract dirt easily. The other problem of course is the grout which due to its cementous nature also attracts dirt and darkens over time.

Polished stone floors do regular attention if you want to keep them looking good and this is why we offer a maintenance program where we pop back to the property once a year to top up the sealer and repolish. In this case the owner also had a dog who was very well natured however dogs are not know for wiping their feet before entering your house.

Stripping and Polishing Tumbled Limestone Tiles

With most polished Limestone floors, I would normally start with a set of burnishing pads which are the best way to restore the finish. In this case however I decided to start the cleaning process with the application of a strong dilution of Tile Doctor Pro-Clean which is left to soak into the stone for ten minutes before being worked in. This gives the product time to digest and breakdown the dirt that gets trapped in the crevices. I then use a silicon carbide brush fitted to a rotary floor machine to work the solution into the stone to bring out the dirt. The soiling is then rinsed off the floor and extracted with a wet vacuum.

The next step was to burnish the stone using a set of Diamond encrusted pads of increasing grits that range from a coarse 400-grit to a very fine 3000-grit. The pads are fitted to the rotary machine and are run across the whole floor lubricating with water which is deployed from a tank on the machine. After each the pad the soiling is rinsed away and extracted with the wet vacuum as before.

I stopped the burnishing process on the first day with the 1500-grit pad and turned my attention to the grout joints which are scrubbed by hand with a wire brush and more Pro-Clean. After another rinse and extract the Limestone and grout was already looking noticeably cleaner.

I returned the next day and set about polishing the floor with the last in the set of burnishing pads which is a 3000-grit pad. This pad is applied with only a little water sprayed on to the stone as its run over the surface, this technique is known as a spray burnish and leaves the floor dry and ready to be sealed.

I was already aware that the owners of the property like the stone to look completely natural and so the sealer chosen was Tile Doctor Ultra-Seal. This is an impregnating sealer that works by soaking into the pores of the stone so dirt cannot become ingrained there allowing it to be easily removed from the surface. It doesn’t change the appearance of the stone at all so it’s almost invisible and difficult to detect which is exactly what they were after. Ultra-Seal is also a great grout sealer and will ensure the grout keeps clean for much longer.

Once the sealer was dry gave the floor an application of Tile Doctor Shine Powder which is a stone polishing compound that is worked into stone, left to dry and then buffed off with a White buffing pad to leave a durable shine on the stone.

Before leaving I took time to discuss aftercare cleaning and left them with a complimentary bottle of Tile Doctor Stone Soap which not only cleans but also help maintain the patina on polished stone.

Chinese Slate Kitchen Floor Renovation Keston

Renovating Chinese Slate Kitchen Flooring in Keston BR2

A client in Keston asked me to freshen up the Chinese Slate floor tiles that had been installed in the Kitchen. Kitchens are the busiest room in the house and overtime the floor had become tired and dull with ingrained dirt, the grout was also stained with dark patches. He had tried cleaning with lots of household products but nothing was improving the appearance.

I visited the property to survey the floor and recommend a solution to the problem. I could see the floor had previously been sealed but it had degraded in several areas and in some places, there was no sealer present at all. Consequently, dirt was able to get into the pores of the stone where it is difficult to remove. All these problems detracted from what should be a very beautiful Slate floor.

To demonstrate my point, I picked a small area of tiling and conducted a test clean followed by the application of a fresh sealer; the floor came up well and my client could see that we could improve the floor significantly. Impressed with the different he was happy to go ahead with my quote and we returned the following month to carry out the work.

There was an old topical sealer on the Slate which had to be removed first. To do this I like to use a combination of Tile Doctor Remove and Go combined with and Tile Doctor Nanotech HBU. I applied the solution to the tiles and grout and allowed it to soak in and get to work for around thirty minutes. The two products combined create a powerful solution that will remove the old sealer and start to break down the stains in the tile and grout.

After thirty minutes, I added water to the solution and scrubbed, paying particular attention to the grout lines, then I vacuumed up the solution using the wet vacuum we have on board. I then went over the tiles and grout with my steamer to ensure I had rinsed and removed all chemicals.

When dry I could see the grout staining was far too deep to be able to get perfectly clean so I applied a grey Tile Doctor Grout Colourant to the grout lines. As well as refreshing the grout to give a consistent and uniform colour it also seals the grout, protecting it with an epoxy barrier making it much easier to clean and maintain going forward. When the grout colourant was dry it was now time to apply the sealer to the slate.

I advised the client to switch from a topical sealer to an impregnating sealer that works by soaking into the stone, occupying the pores, and thereby preventing dirt from residing there.

Happy with my recommendation I sealed the slate with Tile Doctor Colour Grow which as its name suggests contains a colour enhancing formular that it perfect highlighting the natural colours in Chinese slate.

The sealer adds a new level of depth to the Slate and being an impregnator is hardwearing and long lasting. The new sealer will make the floor much easier to clean in future and on that topic I also recommended the use of Tile Doctor Neutral Tile Cleaner for that purpose.

Neutral Tile cleaner is a pH neutral product that is effective yet mild enough not to impact the integrity of the freshly applied sealer. Many household cleaning products are simply too strong for use on a sealed floor (always check the label) and will break down the sealer which may be the reason for the previous sealer failing in the past.

Terracotta Conservatory Floor Renovation Herne Hill London SE24

Terracotta Conservatory Floor Deep Cleaned and Sealed in Herne Hill SE24

The following photos are of a Terracotta floor I recently worked on in the conservatory of a property in the South London suburb of Herne Hill SE25. The room was going to receive a makeover and they were not sure whether to replace the floor or not. The terracotta tiles were very dirty and although they had tried cleaning it themselves, they struggled to get a result so decided to call in Tile Doctor.

I went over to survey the floor and could see that any sealer that was once on the tiles had completely worn away and without the protection of sealer dirt had become ingrained into the pores of the tile. Once that happens it can be troublesome to remove deep seated dirt from within Terracotta due the porosity of the clay-based tile.

However, having done quite a few of these floors previously I was confident with the right approach it could be deep cleaned and then a fresh sealer applied to protect it going forward. On the subject of sealers, they told me that they did not want a shiny finish so I quoted the job to clean and seal with an impregnating sealer that would meet their requirements.

I quoted for two days work, one day to clean and one day to seal and with the quote agreed the work was scheduled.

On my return I started the cleaning process by applying a strong dilution of Tile Doctor Remove and Go combined 1 to 1 with Nanotech HBU Remover. Remove & Go is a multipurpose stripper with a long dwell time designed to remove old sealers and ingrained stains and the “Nanotech HBU Remover” is a heavy build-up cleaning product that uses nano sized particles to penetrate below the surface and draw out the ingrained dirt and stains.

Nanotech is a gel like substance and combined with the Remove & Go it makes for a powerful double action tile cleaning product. For maximum results It was left to sit on the floor for 30 minutes without allowing it to dry up or soak in. I then scrubbed the solution into the floor with a black scrubbing pad attached to a rotary floor machine. This action released the dirt from the tile and grout causing the cleaning solution to go black. The resulting slurry was then rinsed away with water extracted using a wet vacuum.

With the floor already looking significantly cleaner I moved onto the next step of giving the tiles and acid rinse using a 1:5 parts dilution of Tile Doctor Grout Clean-up. This product is a phosphoric acid based cleaner, which amongst other things removes efflorescence and lime deposits, being acidic it also neutralises the strong alkaline chemicals used to clean. I apply this solution by hand using stainless steel scouring pads for the tiles and a wire brush for the grout lines. I work in one metre square sections at a time, not allowing the solution to sit on the tiles for more than five minutes before vacuuming up the dirty solution.

One I had cleaned the whole floor with the “Grout Clean-Up” solution I then rinsed it with a steam cleaner. I use a steam cleaner for two reasons, for one it doesn’t soak the floor and the heat means it dries quicker and two any stains still there get drawn out by the steam.

Sealing Terracotta Conservatory Floor Tiles

It’s not good practice to apply a sealer to a damp floor as the dampness can cloud the sealer and result in a patchy appearance. Because of this I always seal on a second day and in this case, I left the floor to dry out fully for two days before returning.

To seal the floor, I used four coats of Tile Doctor Colour Grow which is an impregnating sealer that soaks into the pores of the Terracotta occupying the tiny pores and thereby blocking dirt from becoming ingrained there. Colour Grow as its name suggests improves the natural colours in the tile and in this case it did well to bring out the Orange/Red colours in the Terracotta, it also leaves a matt finish as requested by the client.

For aftercare I recommend Tile Doctor Neutral Cleaner, sealers are vulnerable to harsh chemicals so its important to use a cleaner that won’t impact them. It’s always worth checking the small print when buying a cleaner as the wrong product can degrade the sealer and then your back to square one with the floor becoming dirty with ingrained dirt.
