Limestone Tile Cleaning and Polishing

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

Cleaning and Renovating Limestone tiles

Limestone is a sedimentary stone, as such it’s generally very porous and acid sensitive and can be damaged through the use of even mildly acidic soaps, shampoos and body washes. Because of this we do not recommend it for use in wet rooms, shower cubicles or near swimming pools.

Like any stone Limestone needs to be sealed to prevent dirt becoming ingrained in its pores and many varieties including Blue Lias, Blue Moleanos, Jerusalem and White Moleanos to name a few can be polished to a high shine using a series of burnishing pads.

We have found that Black Limestone has become very popular in gardens where it contrasts well against green planting and looks fantastic when wet. One issue we find however is it easily upset by the use of acidic patio cleaners that leave the stone looking dull and lifeless. If this has affected you then not to worry we do have a way of restoring the beauty of the stone back to its original condition.

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.


Pale Limestone Floor Clean Seal Walton-on-Thames

Pale Limestone Floor Deep Cleaned and Sealed in Walton-on-Thames

This Pale Limestone floor was installed in the kitchen and adjacent dining area at a property in Walton-on-Thames around three years ago. Unfortunately, it was not sealed after installation and over those three years dirt had slowly become ingrained in the stone giving it a darker/dirty appearance.

Kitchens especially are high traffic areas and so always under attack from foot traffic and spillages from cooking. Additionally, the adjacent dining area had patio doors and was vulnerable to dirt being walked in from the garden.

We always recommend sealing porous flooring material like natural stone such as Limestone. Otherwise, dirt becomes lodged in the pores of the stone and once that happens it becomes very difficult to remove.

I visited the site to survey the floor and carried out a small test clean at one end of the Kitchen to work out the best cleaning solution and to show the client the result that could be achieved.

The test went well, and the clean tiles showed up well against their neighbours. My clients were very happy to see the potential of a full clean and were happy to go ahead with my quotation.

To deep clean the Limestone, it was initially wetted with a strong dilution of Tile Doctor Remove and Go which as is name suggests is a powerful cleaning agent designed to remove coatings and stains from tiles. Working in sections the solution was applied and left to soak into the stone for around fifteen minutes before being scrubber into the tile using a black pad fitted to a rotary floor buffer.

During scrubbing the cleaning solution soon turned black as the dirt was broken down and pushed out of pores in the stone. The soil was then rinsed off the floor and extracted using a low-pressure extraction machine. The buffing pad can struggle to reach into the depths of the grout so after cleaning the tile I gave the grout a good scrub by hand using a strong dilution of Tile Doctor Pro-Clean.

After a final rinse and extraction to remove any remaining products and dirt from the floor you could see huge difference between the clean and original sections of floor. Some areas that were very heavily soiled did need more work though, so the process was repeated until I was satisfied that the floor was as clean as possible. The floor was then left to dry overnight, ready for sealing the following day.

Returning the next day, the moisture level of the floor was checked with a damp meter to ensure it had fully dried out. Satisfied with the readings two coats of Tile Doctor Colour Grow tile sealer were applied to the floor. Colour Grow is a premium impregnating sealer which gives excellent protection against spillages and general foot traffic, making the floor very easy to maintain in the future. I chose this sealer as it improves colour and brings out the best in Pale Limestone.

Once complete the Limestone looked so much cleaner and brighter and as you would expect given the transformation my client was very happy with the work.

Before leaving I took time to discuss aftercare cleaning and with the floor being sealed, I recommended in future they use a milder cleaning product such as Tile Doctor Neutral Tile Cleaner. Stronger household tile cleaning products can prematurely break down the sealer and once that happens, they will soon be back to square one.

Limestone Kitchen Floor Before After Renovation Shepperton

Cleaning a Limestone floor in Shepperton

This customer from the south side Shepperton has a galley kitchen installed around twelve years ago with a Limestone floor. Since that time the floor had not been professionally cleaned or the stone re-sealed. The old sealer had long since worn down and was no longer providing any protection to the floor allowing soil and grease from cooking to penetrate the stone and darken the grout. It was now looking permanently dirty and the owner decided it was time to have it renovated.

Limestone Kitchen Floor Before Cleaning Shepperton

Shepperton is a suburban village in the borough of Spelthorne, the Thames river is to the south and much of the east. It is set between the towns of Chertsey and Sunbury-on-Thames. The village has a long history and is even mentioned in a document of 959 AD and in the Domesday Book when it was primary farm land, it’s also my base of operation.

To deep clean the stone floor and grout I started with a mixture of Tile Doctor Remove and Go combined 50:50 with Tile Doctor Pro-Clean. This cocktail of sealer remover and cleaning agent was applied to the floor and left to soak in for ten minutes in order to get to work breaking down all the dirt, grease and what was left of the old sealer.

The solution was then worked into the Limestone tiles and grout using a rotary machine fitted with a black scrubbing pad. These pads can struggle to reach into the recesses of the grout lines, so afterwards the grout was scrubbed by hand using a stiff brush along with the more difficult to reach corners that the machine had missed. The floor was then rinsed with water and the products and soil vacuumed off the floor. I repeated the process in a couple of areas where the dirt was a little stubborn. The floor was then clean and after drying out overnight it would be ready for a new seal.

The following day I returned to apply the sealer first checking the floor was dry using a moisture meter. The readings were good, so I set about applying a colour enhancing impregnator sealer Tile Doctor Colour Grow to the Limestone. Tile Doctor Colour Grow works by seeping into the pores of the stone intensifying natural colour, preventing staining and providing a durable protection. Two coats of sealer were applied to the Limestone tile and grout which was all that was needed to return the floor back to its original condition.

The client was very happy with the finished floor and wanted to know how to keep it looking its best going forward. I explained that the best way to keep it looking good is to get maximum longevity from the sealer which will wear down over time but can be prematurely damaged with strong cleaning products. So, for aftercare I recommended the use of Tile Doctor Stone Soap which is designed for everyday cleaning of sealed stone floors.

Limestone Tiled Kitchen Floor Before After Cleaning Teddington

Limestone Tiled Floor Cleaned and Sealed in Bushy Park Teddington

This Limestone tiled floor had been installed in the kitchen of a property in Teddington three years before and due to the use of the wrong cleaning product was now stripped of its protective sealer. Limestone like any natural stone is porous and without a sealer in place dirt becomes trapped in the stone making it very difficult to keep clean. The property was close to Bushy Park situated in South West London on the North bank of the Thames which is only about seven miles from my base in Shepperton.

I discovered all of this after visiting the property to quote for deep cleaning and resealing the floor. It turns out they have been using Flash multi-surface & floor cleaner which has an acidic pH of 10.3, compare this to Tile Doctor Remove and Go which we use to strip sealers off floors and has a pH of 12. Needless to say, this was not the right product to use and the old sealer had been completely stripped off the floor and probably within the first few months.

On top of this our customer had 3 children and a dog running in and out of the garden and was therefore transferring quite a lot of dirt into the stone. After surveying the floor, I discussed the renovation process with the customer which would take two days and include a deep clean of the Limestone followed by the application of a sealer to ensure it did not hold onto the dirt. They were after a sheen finish for the floor and were keen to have natural brown and cream variations in the stone highlighted. We agreed a price for the work and booked a date for the work to start.

Deep Cleaning a Limestone Tiled Kitchen Floor

To start with, we machine scrubbed the floor with Tile Doctor Pro-Clean to break down the dirt and release it from the stone. We find the best process is to spray the Pro-Clean onto the floor first and then leave to dwell for ten minutes before scrubbing. It’s not long before the cleaning solution turns dark with the dirt released from the pores of the stone and this soil is then rinsed with water and vacuumed off the floor with a low-pressure hard floor cleaning machine.

Following the cleaning, we honed the Limestone using a sequence of 800, 1500 and finally 3000-grit Tile Doctor Burnishing Pads. The pads are applied with water to lubricate and the slurry generated is rinsed off the floor as before. This burnishing process brings up the natural sheen of the stone and tightens up its pores prior to sealing. I left the floor overnight to allow it to dry out.

The next day I returned to the property and checked the floor for moisture using a damp meter. The readings were fine, so I proceeded with the application of the sealer for which I used two coats of Tile Doctor Colour Grow. This is an impregnating sealer that enhances the colours and contrast on the stone while protecting it against future soiling and spillages. It gave a lovely sheen finish to the floor as requested by the customer.

As you can see from the pictures the process made a huge difference to the floor which now looks lighter and brighter, certainly the customer was more than happy. Before leaving I recommended, they should clean the floor using Tile Doctor Stone Soap, this is a pH neutral product that will ensure the seal does not get broken down like it previously had using the household cleaners. It is gentle enough to use every day if you wish is designed to help maintain the patina of the burnished stone.

Limestone Tiled Hallway Floor Renovated in Shepperton

Limestone Kitchen Floor Tile Clean and Seal in Shepperton

This Limestone kitchen floor in Shepperton was laid new 3 years ago when a new kitchen was installed. The client had called in despair as the floor was just not looking its’ best and they were trying hard to get it clean, using household cleaners which were having no effect. I’m actually based in Shepperton, so it wasn’t long before I was able to pop round and survey the floor. The town has a lot of history and is famous for nearby Shepperton Studios which were built on the grounds of Littleton Park, many famous films have been created here including Attenborough’s Gandhi (1982) and David Lean’s A Passage to India (1984).

As you can see from the pictures, the soil had penetrated the stone as the sealer had broken down over time. The grout lines were particularly bad but also, the small veins and pores had accumulated dirt, mainly due to pets and kids coming in from the garden. It’s worth noting that the use of supermarket cleaning products will have escalated the decline of the sealer, most are simply too strong for sealed surfaces and you should always read the label to ensure its suitable before using it on your floor.

This problem is quite common, and the solution is straight forward. Restoring the look of the floor requires removing the soiling with a deep clean and then when the floor is dry apply a new sealer to protect it. I talked the process over with the customer and agreed a quotation for completing the work which was accepted and arranged a convenient date. The work would be carried out over two days.

Cleaning a Limestone Tiled Kitchen Floor

A strong dilution of Tile Doctor Pro-Clean was sprayed on to the floor and after leaving it to soak in for about ten minutes, we mechanically scrubbed the solution into the Limestone using a rotary floor buffer fitted with a black scrubbing pad. The pads can struggle to reach into the recessed grout however to that was manually scrubbed using more Pro-Clean. This process broke down the soil and released it from the stone and grout. Following this, we used a low-pressure rinsing machine and vacuumed all the soil and remaining cleaning product away from the floor.

Whilst I was working on the floor, I got the shock of my life as a bird hit the kitchen window resulting in a loud bang. I rushed outside to find a beautiful Green Woodpecker lying dazed on the floor, the poor thing had knocked itself unconscious. I put him in a cardboard box until he eventually recovered and flew off. I guess being able to drill into trees makes Woodpeckers tough birds who can withstand a knock or two. In this job no two days are the same, you never know what’s going to happen!

After allowing 24 hours for the floor to dry, we returned the following morning to apply a new seal. The best sealer for this type of stone is Tile Doctor Colour Grow. It is a colour enhancing impregnator that soaks into the pores of the stone protecting it from within whilst enhancing the natural colours in the process. Impregnating sealers work by occupying the pores in the stone thus preventing dirt from becoming ingrained there.

The client was delighted with the floor which now looked cleaner and fresher. We had managed to restore it back to it looking as it did when it was new, and the new sealer will keep it looking that way for some time to come.

Limestone Tiled Hallway Floor Before After Cleaning Twickenham

Unpolished Limestone Hallway Deep Cleaned in Twickenham

These unpolished Limestone tiles were installed in the hallway of a property in Twickenham, Middlesex. The stone had not been cleaned or sealed for six years and being the main entrance to the house it was subject to a lot of foot traffic which had taken its toll on the stone over the years. As you can see from the photos, dirt was ingrained in the stone which happens when the protective sealer wears off with use. They had chosen to cover the floor with some rugs to improve the appearance and make the hall more inviting and as you can see especially where the rugs had been protecting the Limestone there was a visible difference in colour.

Limestone Tiled Hallway Before Cleaning Twickenham

Twickenham is a suburb of London and of course most famous for being the home of Rugby Union in England and a short distance from by base in Shepperton so it wasn’t long before I was able to pop in and survey the floor.

I discussed with the client what could be done to clean the floor and demonstrated the products and technique I would use on a test patch. They were suitably impressed, and we agreed a price for the work and booked a time to complete the job. The job was scheduled for two days, one day to clean and the second to seal the floor.

Cleaning a Limestone Tiled Hallway Floor

To start with, we pre-sprayed the tiles with Tile Doctor Remove and Go and left it to soak in for ten minutes, this allows the product to break down any remaining sealant and greasy soils. Then we machine scrubbed the floor with our rotary cleaner fitted with a black scrubbing pad lubricated with another Tile Doctor product, Pro-Clean. This strong alkaline chemical breaks down the dirt and leaves it ready to be rinsed away.

The grout lines were also cleaned using Tile Doctor Pro-Clean but not with a machine as the pad struggles to reach down into the grout lines, so it was scrubbed by hand to give the best result.

Following the clean, we low pressure rinsed the floor with water and vacuumed all the residue away, leaving the floor ready for sealing. The Limestone tiles and grout looked much better already after cleaning and it was left to dry overnight.

Returning to the property the next day our first action was to check the moisture levels in the floor with a damp meter. All was well so we to apply three coats of Tile Doctor Colour Grow. This is an impregnating sealer that protects the stone from within by occupying the pores in the stone, so dirt can’t become lodged there. The sealer will make the floor much easier to keep clean in future and as the name of the product suggests it also enhances the natural colours in the tile.

For the aftercare of unpolished Limestone, I recommend Tile Doctor Neutral Cleaner which is designed for the cleaning of sealed Tile and Stone. If using a different product always read the label first as many cleaners are too strong for use on sealed surfaces and will strip off the sealer over time.

The client was very happy with the result and felt they could now keep on top of keeping it clean and looking fresh moving forward. They could now remove the rugs too! If you require a free quotation to clean and seal your stone floors do get in touch.

Limestone Kitchen Floor Before and After Cleaning and Sealing in Twickenham

Limestone Kitchen Floor Cleaning and Sealing in Twickenham

This Limestone tiled floor in Twickenham, Middlesex had only been laid eighteen month earlier. However, due to an in-effectual seal on the floor, the soil had accumulated and embedded into the pores of the stone. Limestone like many types of natural stone is a very porous stone and it doesn’t take much for the dirt to build up and start to discolour the floor.

Limestone Tiled Floor Before Cleaning Twickenham

The tile had been laid through out the Kitchen and adjacent dinning area and the solution was quite straight forward and simply required and a good clean and re-seal as detailed below.

Cleaning Limestone Tiles

We started with an application of a strong dilution of Tile Doctor Pro-Clean which was sprayed onto the floor and allowed to dwell for five to ten minutes. Following this, we used a heavy duty floor scrubbing machine in order to break the soil away and existing sealer from the stone.

Once we were happy that the soil and sealer had been dislodged, we then removed all of the chemical and soil via our extraction machine. This applies pressured water onto the stone whilst vacuuming all of the waste away, leaving the floor as clean and fresh as it could possibly be.

Sealing Limestone Tiles

After allowing the floor to dry out overnight, we returned the next morning to apply the seal. Two coats of Tile Doctor Colour Grow sealer were applied to give the best protection possible. Colour Grow penetrates into the pores of the stone protecting it from within whilst also enhancing its natural colours and contrast.

Once done the floor looked like it had just been laid and the customer was extremely happy with the end result.

Limestone Kitchen Floor Cleaning in Hampton

This Limestone tiled kitchen floor in Hampton, Middlesex, was proving troublesome to keep clean and was now in need of a deep clean and re-seal to ensure easy maintenance in the future. Being a high traffic area the tile and grout had accumulated a high amount of soil over the years and the tiles had lost their shine due to wear on the face of the stone.

Cleaning Limestone Tiles

I gave the floor a quick wash down with a dilution of Tile Doctor Pro-Clean to ensure we had removed any surface soil and grit and then proceeded to burnish the Limestone tiles using a set of diamond abrasive burnishing pads fitted to a heavy rotary machine. You start with the coarse pad which cuts through the stone and removes any remaining old sealer and soil and then smooth off the surface ready to receive a new seal using the medium, fine and extra fine pads until a highly polished finish is achieved.

The grout lines were then scrubbed by hand using more Tile Doctor Pro-Clean and a fair amount of elbow grease; the whole floor was then washed down with the water being removed from the floor using a wet vacuum.

Sealing Limestone Tiles

The floor was then left for twenty four hours to allow it to dry and then I returned to seal the Limestone and Grout using two coats of Tile Doctor Colour Grow. This is an impregnating sealer that occupies the pores in the stone so contaminates cannot become ingrained in the stone making it easier to clean in the future. Hopefully you can appreciate from the pictures how transformed the kitchen now looks.
