Limestone Tiled Kitchen Floor Renovation Geddington

Pitted Limestone Floor Deep Cleaned, Polished, Filled and Sealed in Geddington

This client from Geddington called me in to renovate their Limestone tiled floor which had been installed throughout much of the ground floor. Limestone like any natural stone is porous and will suffer from ingrained dirt if the sealer isn’t maintained, so it’s not unusual to need work like this doing every three to five years.

I visited the property to survey the tiles and could see the stone had quite a lot of surface pitting which was trapping dirt and making it very difficult to keep clean. Pitting is quite common in this type of stone, and they are usually filled at the factory, however the filler can become dislodged with wear and the problem can be made worse by the use of acidic cleaning products.

After surveying the floor, I came up with a comprehensive renovation plan that included deep cleaning the stone, filling the pits, polishing, and then sealing. I also made a note to discuss aftercare cleaning at the end so the floor wouldn’t get so bad in future.

Happy with my plan and quote a date was agreed for the work to commence.

Cleaning a Pitted Limestone Tiled Kitchen Floor

It was a large floor so to minimise disruption to the owner I split the job up into several areas and worked through the following process.

Work started with a general clean of the floor using Tile Doctor Pro-Clean with a focus on cleaning the grout. I used a strong dilution of Pro-Clean, left it to soak into the stone and grout for around ten minutes and then scrubbed it into the floor using a black pad fitted to a rotary machine. I also ran a stiff grout brush along the grout lines to get them as clean as possible. Once done the floor was rinsed and the soiling extracted with a wet vacuum.

The next step was to hone the Limestone using a set of diamond encrusted burnishing pads. These pads are great for bringing up the polish on a stone floor like this and you start with a coarse 400-grit pad fitted to a rotary floor buffer. Water is used to lubricate the process and the pads are run over each tile three or four times. The floor is then rinsed and extracted as before, and the process repeated with the 800 and then 1500 grit pads.

Once done the floor was looking much cleaner and brighter and ready for the next step which was to fill the pits. To do this I inspected the floor, identifying all the areas that needed attention and then filled those holes with a resin filler that is colour matched to the stone.

The last step was to seal the limestone and for this I used Tile Doctor Ultra-Seal which is an impregnating sealer that soaks into the stone, occupying the pores of the stone and thereby preventing dirt from residing there. Sealing keeps the dirt on the surface where it can easily be cleaned away. Ultra-Seal doesn’t contain any colour enhancers, so it leaves the stone with a very natural appearance which is what my client wanted.

The floor was transformed by the work and my client was very happy with the result, they even went to the trouble to leave the following review:

“We are absolutely delighted with the work undertaken by Philip, the Northamptonshire Tile Doctor. He has completely transformed very dirty limestone floors into something of great beauty – better than new. Philip was a pleasure to deal with throughout and we can highly recommend him.”

With regards to aftercare cleaning, I recommended they use Tile Doctor Stone Soap which is designed for cleaning polished stone floors and helps maintain the patina.

These photos are of a four-year-old Limestone kitchen floor at a property in Boughton that the customer was finding hard to keep clean and maintain a shine. Part of the problem was he owned two dogs and we often warn about the problems of dog urine on sealed tile and stone due to it being high in nitrogen.

On my initial visit I was able to ascertain that the sealer had almost completely worn off, leaving the stone vulnerable to dirt becoming ingrained into the pores of the stone. I come across this problem a lot, in my experience when stone floors are installed by tilers, they generally apply a single coat of sealant which wears off over time, and as discussed earlier can be prematurely degraded by strong chemicals.

My quote to renovate the Limestone floor was accepted and included a deep clean to the stone and grout, stone polish and then re-seal.

Cleaning/Polishing Limestone Tiled Flooring

I arrived on site on the arranged date and began by scrubbing all the grout lines with Tile Doctor grout brushes and a 3:1 dilution of Tile Doctor Pro-Clean. I then moved on to a small handheld polishing machine to clean around the tile edges using 800 and 1500 grit diamond encrusted burnishing pad to achieve a deep clean.

The process was then repeated throughout the rest of the area using larger 17” burnishing pads fitted to a floor polishing machine. The burnishing pads I used come in a set of four starting with 400-grit and moving up to 800, 1500 and 3000 grit, after each pad is applied the floor is rinsed with water and the soil extracted with a wet vacuum.

It took me much of the day to complete this stage of the renovation and the floor was still damp so once done I left for the day, allowing the floor to dry off overnight.

I returned the following day to complete the final polish using the 3000-grit burnishing pad, this gave a high polished finish which the customer had requested. This last pad is applied dry with only a little water splashed onto the tile, a process we call a spray burnish.

The floor was then sealed with three applications of Tile Doctor Ultra Seal Sealant to protect the newly restored and polished tiles. Ultra-Seal is a penetrating sealer that soaks into those recently cleaned pores in the stone, occupying the space and preventing any dirt from becoming ingrained there. It’s also a natural look sealer so it doesn’t change the colour of the stone in anyway and is almost indetectable once applied.

“Hard work from Philip has left us with a kitchen floor brought back to life – cleaned and sealed in little over 24 hours – brilliant job – Thanks”

Before leaving I gave the customer some tips on maintenance and a complimentary bottle of Tile Doctor Stone Soap to enable him to keep the floor looking its best, this product works well with the sealant we applied and is PH neutral so won’t degrade the new sealer.

This Limestone tiled floor installed in a kitchen and family room at a property in Wellingborough is a great example of how this material can lose its appearance without a regular maintenance plan in place.

Limestone Tile and Stained Grout Before Cleaning Wellingborough

The customer called me as not only was she concerned that the floor had lost its lustre the grey grout had become very stained and almost black in heavy traffic areas, in fact my customer had originally asked about re-grouting but I was confident it could be cleaned.
I provided a quote which they were happy to accept.

Cleaning/Polishing Limestone Tiled Flooring

The area was a nice wide 6 metre by 5 metre space and except for a few items of furniture that would need moving around there were relatively few obstacles. I reasoned the most efficient way to restore the polished appearance of the Limestone would be to use a set of diamond encrusted Burnishing Pads. These are fitted to a rotary machine and applied to the stone in sequence from coarse to smooth. It’s an effective process that cuts back the layer of dirt on the floor and then we build back up the polish.

We started burnishing the Limestone with a coarse 400-grit pad fitted to a rotary machine and applied with a little water for lubrication. The coarse pad is very good at removing dirt and old sealers from stone and once completed the resultant surface water and loose dirt is removed using a wet vacuum.

At this point I turned my attention to the badly stained grout lines, and applied a strong solution of Tile Doctor Pro-Clean which was scrubbed in along the grout lines using a stiff grout brush, this is necessary as the recessed nature of the grout makes it difficult for the rotary pads to reach it.

I then repeated the burnishing process with the medium 800-grit pad and fine 1500-grit pad, the 800-grit pad removes any small surface scratches and the 1500-grit further refines the look of the Limestone slowly restoring its polished appearance.

After the whole floor had been burnished in this way it was given a further rinse with water and the soil extracted as before. I then inspected the floor to see if more work would be needed.

I was not fully happy with how some of the grout lines had responded, some were still slightly stained, and some marks were visible in the high traffic areas. I had already discussed on my initial visit with the client that this might be the case and it was agreed between us that should this be the case I would apply a Tile Doctor Grout Colourant in Light Grey to recolour all the grout lines and achieve a uniform finish.

The stone and grout was still damp from cleaning and polishing, so I decided to leave the grout colouring until the following day.

On day two I started by grout recolouring all the grout lines, it’s a straight forward process but can be a little tedious where there is a lot of grout to cover. Once complete I allowed the grout colour to dry for a couple of hours before moving onto the next step.

The last pad to be applied in the stone burnishing process is the very fine 3000-grit polishing pad which is applied dry to the tiles using a small amount of water sprayed onto the floor and leaves the stone dry and with a polished silk finish.

The floor was then sealed using two coats of Tile Doctor Ultra Seal Sealant allowing the first coat to dry before applying the second. Ultra-Seal is an impregnating sealer that works by occupying the pores in the stone thereby preventing dirt from becoming ingrained there. It’s also a natural look sealer that doesn’t affect the appearance of the stone
