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 East Wales

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.


Black Limestone Patio Restored in Cardiff

Cardiff Patio Ruined by a Builder Restored in Cardiff

This customer from Cardiff was in despair after a builder ruined her expensive Black Limestone Patio after using brick acid to clean it up. She contacted Tile Doctor in the hope that it could be saved and being their local agent, I was asked to contact her.

I visited the property to assess the damage to the patio and it was immediately clear to me what needed to be done as this is not the first time I had come across this problem. It turns out the builder was attempting to remove cement splatters from the stone after applying render to the back of the property. Limestone is a sedimentary stone composed primarily of calcium carbonate which can be dissolved in acid, so using acid on Limestone is never a good idea.

I spent the first day removing the damage to the stone by burnishing the patio with a weighted buffer machine fitted with a 100-grit diamond pad lubricated with water and using a wet vacuum to remove the soiling it generates.

This was followed by a 200-grit, 400-grit and then finished with an 800-grit diamond pad until I had removed all the damage and resurfaced the Limestone. Again, water was used to lubricate the process and the floor was rinsed with fresh water after each pad and the soil extracted with a wet vacuum.

This work was done in August 2022 and I had purposely chosen a patch of good weather to do this work and was able to leave the patio to dry off overnight after another thorough round of rinsing with water and extracting.

I returned the next day to finish the renovation, first checking first that the stone was dry with the use of a damp meter. The readings were good, so I went ahead and applied the sealer. Secondly its recommended for outdoor use and is UV safe so should last a long time ensuring the patio will now be able to withstand the outside weather and the stone will be protected from the elements.

The results were amazing, and my customer was relieved and delighted with the finished result allowing her to look forward to several summer garden parties that were planned.

Verde Limestone Kitchen Floor Renovated Cardiff

Vomit Damaged Verde Limestone Floor Renovated Following Drunken Party in Cardiff

The young gentleman who owned this property in Cardiff was distressed about his new Verde Limestone kitchen floor. He explained to me that he recently had a party at the house and one of his friends drunk too much and vomited over the stone floor. Easy enough to clean up you would think, however in a rush to clean up the mess he slipped banged his head on the corner of the worktop and ending up bleeding onto the sick.

Thankfully his friend was ok. but unfortunately, the acid from the stomach, had caused the surface of the Limestone to be etched quite considerably and now appeared to show permanent wipe marks across some of the floor. Thankfully I advised that we could repolish the surface of the stone to rectify the problem, and this would soon have his floor looking good as new again. The 12mm Verde Limestone tiles have a lovely green shade and set the newly fitted kitchen off a treat. We agreed a price for the work, and I booked the job in soon after.

Cleaning a Limestone Tiled Kitchen Floor

To restore the appearance of the floor it needed to be burnished with a set of Tile Doctor Diamond encrusted pads which resurface the tile and rebuild the polish. I started with an abrasive 400-grit pad fitted to a weighted rotary machine worked into the Limestone using only water to lubricate the process. The floor is then rinsed with water to remove the soil which is then extracted with a wet vacuum. This process is repeated using an 800 , 1500 and finally a 3000-grit until the surface of the floor was restored with a high polish.

The grout was then cleaned with Tile Doctor Pro-Clean which is a versatile cleaning solution ideal for grout cleaning. It’s diluted with water and then left to soak into the grout line for a short while before being scrubbed in. After scrubbing the waste is rinsed off with water and extracted with the wet vacuum.

The floor was left to dry overnight with assistance from a floor flan so it would be nice and dry for sealing the following day. By the end of the first day the stain was gone, and the Limestone looked so much better, much to the relief of my client.

The next morning, I took a few moisture readings from the tile to make sure it was dry and ready for sealing. The readings were fine, so I set about applying Tile Doctor Stone Oil to the stone. This product soaks into the pores of the stone restoring the natural oils to the stone and enhance the strong dark green colour of the Verde Limestone.

The Limestone needed to be dry before continuing with the last stage of sealing so stone oil was left to dry off overnight and I came back the next day to finish off. People may get the impression from reading this that I am a little over cautious, but I’ve learned from experience that applying a sealer to a damp floor is not a good idea.

So the next day I returned to seal the tiles and for this floor I used three coats of Tile Doctor Colour Grow which is impregnating sealer that protects from within whilst enhancing the natural colours in the stone. The combination of the Stone Oil and Colour Grow add long lasting protection to the stone whilst improving its appearance.

The gentleman in question was over the moon with the result as he left the following glowing feedback for me; I understand he is not planning any more parties any time soon!

We are absolutely delighted with Julian’s work! Our limestone kitchen floor was very damaged and we were worried that the damage would be irreparable – Julian diamond polished and resealed the floor and it looks like new. He was an absolute pleasure and the quality of the work was amazing. I will definitely be getting in touch to help preserve the floor in the future. Thank you!

Bathstone Window Cills Before and After Cleaning Cardiff

Dirty Bath Stone Cill’s Deep Cleaned in Cardiff

Bath Stone is a material that we don’t often encounter. A variation of Limestone, its distinctive yellowish or ‘honey’ colouring is best associated with historical buildings in the City of Bath – hence the name ‘Bath Stone’. However, it has commonly been used as a building material throughout southern England and Wales.

The owner of this property in Cardiff was quite upset that her Bath Stone window sills had become so unsightly over the four-year period since her house was built, so much so that she contacted Tile Doctor to see if we could help.

Cleaning Dirty Bath Stone Window Sills

While at Tile Doctor we most often work on tiled floors, patios and shower cubicles, I was more than happy to assist in this situation. I popped round to the property to carry out some initial cleaning tests on an inconspicuous area of one of the window sills.

I applied Tile Doctor Pro Clean, which is our high alkaline cleaner, since it’s a very versatile and reliable product, and is suitable for use on most kinds of natural stone. Some fantastic results were achieved quickly, with Pro Clean working efficiently to remove the green and black algae that I presumed came from the trees which were plentiful around the property.

With the test clean a success, we agreed a date to complete the job. I returned on the agreed date with a ladder to treat the rest of the sills using Pro Clean, including the one on the first floor window.

Before carrying out the work, I tested the stone for moisture and the readings were sky high. Therefore, I suggested to the customer not to seal the stone, but instead to maintain it using the same cleaning process as I had undertaken.

The outcome of my restoration was brilliant, so now when the customer feels that the sills need to be rejuvenated again, she can do so very easily.

Polished Limestone After Burnishing Cowbridge

Heavily Worn Polished Limestone Floor Restored in Cowbridge

When given the right care, a polished Limestone floor can be an amazing asset to any house. If neglected, however, the tiles can quickly discolour from wear, especially in areas of high traffic, such as the kitchen.

Such was the case at this house in the small, picturesque town of Cowbridge, in South East Wales. My client had contacted Tile Doctor to see what could be done to improve the condition of the tile and grout which, as you can see from the photographs had not been properly maintained.

To get the floor back to its best it would need to be burnished which is a process that rejuvenating the appearance of polished stone through the application of different grades of diamond encrusted floor pads from coarse to very fine.

Re-Polishing Limestone Floor Tiles

Before beginning the burnishing process, I made sure to check that there were no inherent moisture issues using a damp meter, the home owner had informed me beforehand that the floor did have a damp proof membrane installed however it is always a good precaution to check and additionally it provides a good baseline for later when checking the floor has dried after cleaning.

Burnishing and Sealing a Limestone Tiled Floor

The Tile Doctor burnishing system consists of four main burnishing pads. I began by applying the coarse pad to the tiles lubricated with a little water, before rinsing the floor and moving on to medium and fine grit pads again lubricating with water and rinsing after each pad. After finishing with the third pad, I paused to rinse the entire area a thorough rinse extracting the resulting waste with a wet-vac machine.

I then paid special attention to cleaning the grout lines, which had turned black in places. I applied undiluted Tile Doctor Pro Clean and agitated the grout lines with a stiff scrubbing brush to restore the original colour. This was followed by another thorough rinse.

I left the floor to dry overnight, before completing the burnishing process by applying the final very fine grit pad which adds that aesthetically pleasing shine. I used the damp meter to check the floor had dried and once I was happy I began the sealing process with the application of three coats of Tile Doctor Colour Grow. Colour Grow is a great choice for Limestone as it penetrates into the pores of the stone protecting it from within whilst enhancing the natural colours in the Limestone. As a final step and to ensure there were no unappealing marks left on the floor, I went back over the floor once more with the fine grit burnishing pad.

What was once a dull stone floor with dirty grout lines has now been restored back to its original condition and with the correct maintenance going forward should stay that way for some time.

Limestone Reduxa After Stain Removal

Restoring A Stained Limestone Tiled Kitchen Floor in Cardiff

The following post is follows on from the Limestone tiled kitchen floor restoration I recently completed in Cardiff. You may recall that the floor had not been maintained properly since it was first installed in 2008 and one of the key problems I had to deal with during that particular restoration was a number of dark stains left on the tiles by the kitchen dustbin. Here’s a detailed account of how I tacked the staining.

Cleaning a stained Limestone tiled floor

To deal with the stains, I suggested to the client that I experiment with a Tile Doctor product called Reduxa, which is formulated to remove certain stains, including red wine stains, from natural stone. It is suitable on Limestone, Marble and Travertine tiles, amongst others. Nonetheless, I did have to advise the client that unfortunately some stains are unavoidably permanent and that there was no guarantee that the product would be able to remove these particular stains. Had the sealer been maintained on this floor, then the problem would have been much easier to tackle. However, in this case the sealer had worn off over the years.

I began treating the problem area by applying the Reduxa solution, before heating up the tile with a heat gun to lift out the stains. This process of spraying and heating was repeated around eight times.

To cut a long story short, the process worked very well, and both myself and the client were amazed at the results the Reduxa stain removal solution had on the floor. This product really does what it says on the label!

Unmaintained Limestone Kitchen Floor After Cleaning Cardiff

Unmaintained French Limestone Tiled Kitchen Floor Restored in Cardiff

This customer from the historic city of Cardiff was keen to see what Tile Doctor could do to put some life back into their treasured Limestone kitchen floor that was laid in 2008. My first observations were mainly centred on the horrific condition of the surface which although adequately sealed initially the floor had not received any subsequent maintenance and its condition had deteriorated over time. The light shining in from the patio doors highlighted all the imperfections in the floor caused by surface wear and tear commonly seen in high traffic areas such as a kitchen.

Upon closer inspection, there were further problems: the floor was stained and scuffed, and in most places the sealer had worn off completely allowing the dirt to become ingrained into the pores of the Limestone. Additionally the grout was recessed but was now flush with the tile surface due to dirt build-up. There were also areas contaminated with grease and kitchen cooking oil.

The Limestone floor tiles were 20mm thick French Limestone, and had been laid very well so there was no requirement to do any tile or grout repairs however to get this floor back to its original condition the surface would need to be reconditioned using the Tile Doctor four stage burnishing system.

Restoring a French Limestone Floor

I started by giving the floor a wash with a medium dilution of Tile Doctor Pro-Clean, focusing mainly on the grout lines in order to remove the muck that had built-up there. I used a special stiff grout brush for this activity; it’s quite narrow and ideal for grout scrubbing.

This worked well, but the significant build-up of dirt along some of the grout lines meant more work was required. I tackled this problem with a hand scraper assisted with steam. At the end of this process, the whole floor was then rinsed down with water to remove any soil and the resulting slurry was then extracted using a wet vacuum.

Burnishing French Limestone Tiles

The next step was to start the burnishing process, which basically involves applying four diamond encrusted floor pads in sequence over the floor. Each pad is a different grade, starting with the most abrasive coarse pad and moving through to the finer grades using a little water to lubricate and rinsing away any slurry between each pad.

I eventually finished with the extra fine pad which builds up shine and lustre on the tile; it had taken two days to clean the grout and burnish the Limestone but the floor was much improved and so after a final rinse down I left the floor to dry off overnight with the aid of the underfloor heating.

During this time, I also addressed the stained Limestone in the area of the kitchen where the dustbin was situated. This had been a major upset for the customer and I’m happy to report I managed to deal with it. However, it was quite an involved process, so I’ll write about this in a separate post.

Sealing a Limestone tiled kitchen floor

On the third day I came back to seal the floor, checking first that it had dried sufficiently with a damp meter. Fortunately, the underfloor heating had done a great job of drying the stone and I was able to seal the floor using three coats of Tile Doctor Colour Grow sealant. This sealant not only provides a durable seal but also penetrates deep into the pores of the stone protecting it from within and enhancing the natural colours of the Limestone in the process.

After the final layer of sealant, I worked over the floor again with the extra fine burnishing pad both to add shine again following sealing, and to ensure that no smear marks were visible as the lighting conditions were unforgiving and highlighted any imperfections.

The customer was delighted with the results: so much so, in fact, that they booked me in to restore their Victorian hallway floor as well but that’s a story for another time!

Polished Limestone Central Cardiff Offices after

Polished Limestone Reception Floor Cleaned in Central Cardiff

We were engaged by a commercial maintenance contractor to clean the large Limestone reception floor area of a very prestigious office building in the centre of Cardiff. The office’s main tenant is a bank and the owners were keen to restore the floor as they were letting out the remaining office space and keen to show off its potential to other businesses. The Limestone floor had been laid in 2009 and naturally being a reception area had seen a lot of foot traffic and the standard cleaning process was struggling to keep pace with the ingrained dirt and would now need to be burnished with diamond encrusted pads to remove the ingrained dirt and bring back the polish.

First went over the area with a very course black burnishing pad fitted to a rotary cleaning machine and a little water to remove the worst dirt and cleaned the grout lines with Tile Doctor Pro Clean in the process with a stiff grout brush. For stubborn areas I mixed in a little Tile Doctor Nanotech HBU which deals with the heavy build-up of dirt, rinsing and extracting the soil with a wet vacuum as I worked.

Once the main ingrained dirt was lifted I moved onto the a medium burnishing pad which is the first step in restoring the surface back to its normal appearance; this was followed with the next pad in the sequence all the time lubricating with water as you go. The floor was then given a thorough rinse to remove any soil created by the processes and left to dry overnight.

The next day the floor was given a final polish with the last burnishing pad which is super fine and then it was sealed including the grout lines with a couple of coats of Tile Doctor Colour Grow which impregnates the stone to prevent contaminates becoming ingrained into the tile, it also enhances the natural colours in the stone. Last step was a final run over with a buffing pad to ensure any blemishes were removed.
