Putting the Polish back on a Dull Limestone Floor in Gloucestershire

The photographs below are of a Polished limestone floor that had been installed in the Kitchen of a house in Cheltenham approximately eight years prior. The polish and sealer had worn off over that time allowing dirt to become ingrained into the pores of the stone making it difficult to clean.

This is a common problem with all types of porous stone and tile which need to be sealed to maintain their appearance. Sealers do wear down over time with use however and need to be maintained, this is why Tile Doctor have created a maintenance program whereby we pop by every 12 months to give the floor a light clean and top-up the sealer, it only takes a few hours, but it keeps your sealer in good condition.

Cheltenham by the way is a lovely town situated on the edge of the Cotswolds which is an area of Outstanding Natural Beauty. It has a racecourse and is well known for the mineral springs which were discovered here in 1716.

Burnishing a Dull and Dirty Limestone Tiled Floor

My first job was to protect the wooden kitchen units from any splashes by covering them some cotton sheets. Next, I set about restoring the Limestone’s appearance using a set of Burnishing Pads which is a form of polishing which involves the sequential application of four diamond encrusted pads of different grit levels.

The first pad applied is a Coarse 400 grit pad which is applied to the floor with a buffing machine and lubricated with water. This process grinds away the top layer of dirt and staining from the stone, along with any old sealer, the floor is then rinsed to remove the soil that is generated. I then move through the system, applying the Medium and then Fine pads using less and less water as you go but rinsing in-between and extracting the water with a wet-vac machine.

Once I was happy with the stone I scrubbed the grout lines to remove any soiling that the pads had failed to pick up. The floor was then given a final rinse and the wet vacuum used to extract as much moisture as possible. The floor was then left to dry out completely overnight.

The next day I gave the floor a polish with the Very Fine 3,000 grit diamond burnishing pad, this is applied using a technique we call a “spray burnish” due to the fact that very little water is used during its application.

The next step was to seal the stone using for which I used Tile Doctor Colour Grow which is an impregnating sealer that protects the stone from within by occupying its pores. Colour Grow also has the added benefit of intensifying the natural colours in the stone. The floor was then left to dry for an hour before I gave it one final dry polish using the Very Fine burnishing pad.

Removing a Wood Sealer from Limestone Tiles in a Gloucestershire Kitchen

Slightly different story for you below; this time from the medieval town of Tewksbury which dates all the way back to the 8th century. A customer there had asked if there was anything that could be done to restore the appearance of their polished Limestone kitchen floor on which he had previously applied a wood sealer which had turned the tiles brown.

I inspected the floor and ran a test clean on a small section of tile which successfully removed the wood seal. This gave the customer the confidence to book me into to complete the job which I estimated would take three days to strip off the old sealer, deep clean and reseal with a more appropriate product.

You probably can’t appreciate how bad the tiles looked from the photograph above but if you look at the indicated area under the kitchen units where the kick boards have been removed you can really see how the brown stain in the wood sealer has darkened the look of the tile.

Removing Old Sealers from Limestone Kitchen Floor

On the first day I prepared the area by removing the kick boards from the underneath the kitchen units so they wouldn’t get affected by the cleaning process and started wetting the floor with water. The water lubricates the burnishing process whereby coarse diamond encrusted pads are applied to the floor with a buffing machine. We started the process using a very coarse 100 grit milling pad to remove the wood sealer before moving onto the finer pads from 200 grit, 400 grit, 800 grit and finally 1500 grit pad building the finish of the floor as we progressed. The floor is rinsed with water between pads and the slurry is removed using a wet vacuum.

This burnishing process took up all of the first day so the next day I returned to focus on the edges I had missed and the grout lines, being a relatively small format tile for Limestone there was a lot of grout to cover. I tacked the grout lines with Remove and Go which is a powerful stripper and cleaning agent which is applied along the grout line and then scrubbed in with a narrow stiff brush before being rinsed away with water. The edges were treated with a set of small six inch milling pads fitted to a hand held buffing machine in a similar process as on the first day.

On the third and final day the floor was spray burnished which a process is involving a very fine 3,000 grit floor burnishing pad and a little water spayed onto the floor during the application. This process really tightens up the pores in the stone and restores its appearance.

After making sure the floor was free of any lose grit I then proceeded to seal the Limestone with Tile Doctor Ultra Seal which is a natural look sealer that doesn’t alter the appearance of the stone but penetrates into the pores of the stone to protect it from within. I left it to dry for an hour then buffed the floor with a white buffing pad before apply a second coat. This was also left to dry for an hour before running the buffing pad over for a last time.

It took a fair amount of work to get the floor looking back the way it was meant to be but I’m very pleased with the outcome and more importantly my customer was really happy.

Putting the Polish back on Limestone Floor Tiles in Gloucestershire

This customer was looking to rent out his property in the East Gloucestershire town of Cirencester, the largest in the Cotswold District. However, he found that many prospective tenants were put off by the condition of the Limestone floor tiles on the ground floor.

Over the years, the sealer had worn away and that had allowed for dirt and stains to become ingrained in the pores of the stone, leaving the Limestone tiles looking very dull, unclean and generally undesirable. To boost his chance of finding a tenant for the property, the customer asked me to come in to restore the Limestone tiles to their best possible condition.

I arrived at the property and conducted a survey to assess the situation. The customer – not wanting to waste any more time – asked if I could complete the restoration straight away, fortunately I was able to shuffle a few things around and was able to make a start two days later.

Burnishing a Dull and Dirty Limestone Tiled Floor

With Limestone, as well as other high-end stone like Marble and Travertine, we find that the best method for restoration is burnishing. This is a form of polishing which involves the sequential application of diamond encrusted pads of different grit levels.

We work with a system of four pads fitted to a buffing machine. The first is a Coarse pad, which grinds away the top layer of dirt and staining from the stone, along with any old sealer. I then moved through the system, applying each in turn the Medium, Fine, and Very Fine burnishing pads to gradually refine the polish on the floor. A small amount of water was used as lubricant between each pad, and I hoovered up any resulting slurry with a wet-vac machine.

Having finished polishing the stone, I paid attention to cleaning the grout lines, applying Tile Doctor Remove and Go, which draws out any ingrained stains and heavy grease build-up, and scrubbing it in with a specialised grout brush. The floor was then left to dry out completely overnight.

Upon returning to the property the next day, I checked the floor was completely dry and quickly vacuumed up any leftover debris from the previous day’s work. Next, I gave the floor another polish with the Very Fine 3000 grit diamond burnishing pad, vacuumed it again, and it was then ready to be sealed.

To do this I used Tile Doctor Colour Grow, which is an impregnating sealer that not only acts to protect the stone, but also intensify its natural colours. The floor was then left to dry for an hour, before I subsequently gave it one final dry polish using the Very Fine burnishing pa fitted to the buffing machine. After vacuuming up any debris, I applied a second coat of Colour Grow, left it to dry, and finally buffed it with a soft white pad.

The customer was really pleased with the results, having never expected for the restoration to turn out so well. Undoubtedly there will a queue of prospective tenants hoping to see the property now that the Limestone tiled floor looks so great!
