Dull Black Limestone Patio Renovated in Gerrards Cross

This customer from Gerrards Cross contacted me about their Black Limestone patio which had not been laid that long ago but was already in need of attention. Having spoken to the owner on the phone I arranged to visit the property so I could assess the issues in full and prepare a quote.

I visited the property to survey the patio and could immediately see that the Black Limestone flags looked washed out and grey, nothing like the beautiful dark stone he was expecting. It was clear that the installers hadn’t done anything to the stone after laying the patio, excess grout (grout haze) needed removing and no protective sealer had been applied resulting in staining from plant pots and spillages.

I recommended a restorative treatment involving deep cleaning, removing the grout smears, oiling to restore texture and the application of a colour enhancing sealer. This process would restore its original appearance and get the patio looking as it should.

Happy to hear the situation could be resolved my quote was accepted and a date scheduled for the work to begin.

Cleaning and Restoring a Black Limestone Tiled Patio

I arrived on the first day and started by helping the customer move furniture off the patio so I had a clear work area. Then work started off by scrubbing the stone with a Rocky floor machine fitted with a silicon carbide brush. This action gets into the stone giving them a deep clean, with the brush I also applied Tile Doctor Pro-Clean which is a strong alkaline cleaner and left that down for fifteen minutes to soak in first. With the dirt released from the stone onto the surface a wet vacuum is used to hoover up the resultant slurry.

Once cleaned the patio was inspected and I could see there was still evidence of grout haze on the Limestone so I used a 400-grit burnishing pad with water to take if off and then left the patio to dry out overnight ready for sealing. This work as actually carried out in the summer of 2022 so the weather wasn’t a problem.

On the second day work started by checking the moisture readings of the Limestone tiles using a damp meter. The readings were within tolerance so I was able to apply an initial coat of Tile Doctor Colour Grow sealer which is a colour enhancing impregnator that soaks into the pores of the stone. A very thick first coat was applied and allowed to soak in which it did very quickly.

This was then followed by a thick coat of Tile Doctor Stone Oil and allowed to soak in for roughly an hour before buffing it with a cloth to collect any excess residue. The Stone Oil gave the tiles a very deep black colour which seeped into the stone and this is exactly the appearance my customer wanted. It was quite the transformation from the dull washed-out looking patio that was here before.

Finally, I applied a third and final coat of Tile Doctor Ultra-Seal resulting in a resilient sandwich of coatings that should keep the stones appearance for some time to come. This last coat was applied using a microfibre cloth allowing it to seep into the stone. Once I felt the Black Limestone had dried sufficiently, I used a white buffing pad to buff over the patio and remove any residue.

The customer was very happy with his new patio and recommended me to a neighbour who had a similar problem with their patio.

Smooth Indian Sandstone Kitchen Floor Renovation Gerard's Cross

Smooth Indian Sandstone Kitchen Floor Transformed in Gerrards Cross

This client in Gerrard’s Cross wanted to be able to see the different colours and features in their Sandstone Kitchen floor and to remove the ring marks which you can see in the photograph. They had just moved into the house in and loved the Stone floor but soon realised the previous owners hadn’t taken much care of it. They tried a selection of supermarket products to clean the floor but none of them made much of difference.

I carried out a site visit and it was clear to me that what was once a light Sandstone have literally darkened with all the dirt it had absorbed. I was confident that the dark stone could be deep cleaned and lightened to give them what they wanted, and then protected with a fresh sealer to ensure it remained that way. I worked out a quotation which they agreed to, and we arranged a date for the work to start.

Deep Cleaning a Sandstone Tiled Kitchen Floor

Day one of the work started by deep cleaning the Indian Sandstone tiles and removing as much of the dirt that become stuck in the pores of the stone as possible. To do this the floor was wetted with a strong dilution of Tile Doctor Pro-Clean which is our go to tile and grout cleaning product.

After leaving it to soak in for ten minutes the solution was scrubbed int the stone and grout using a rotary floor buffer which was setup with a black scrubbing pad. This action drew the dirt and any remaining old sealer out to the surface where the soiling could be extracted with a wet vacuum.

The next step was to refinish the surface of the stone using a set of Tile Doctor’s Diamond Burnishing Pads. Starting with a 400-grit pad to remove the ring marks in the floor created from plant pots and then continuing through the different grits from 800 to 1500 grit which gave the floor a natural sheen and then a 3000-grit pad to finish. The floor is rinsed with water between pads and the slurry generated extracted with the wet vacuum as before.

The lower grit pads are applied with water to help lubricate the process however the last pad is applied almost dry with only a little water sprayed onto the floor so by the time the process in completed its well on its way to being dry.

I left the floor to fully dry off overnight and came back the next day to apply the sealer. Before starting thought I gave the floor another run over with the 3,000-grit pad just to tighten the pores before sealing.

To seal two coats of Tile Doctors Ultra-Seal were applied, this is an almost invisible product recommended for use in food preparation areas that leaves the stone in a natural finish which was the effect my client had requested. They had long French patio doors leading onto the garden and wanted to allow as much light in as possible because before the floor was cleaned the room was quite dark.

After allowing the seal to soak into the Indian sandstone I gave the floor one last buff with a fresh 3000 grit pad to burnish more of a natural sheen onto the floor and to bring out the colour definition.

Once complete the floor was transformed from dark to light and looked so much cleaner. My client was very impressed by the work and surprised at how different the floor looked with the colours coming through and said she would recommend me to her friends and family in the area.

For after care I recommended the use of Tile Doctor Stone Soap which is a gentle cleaner that won’t degrade the sealer and will help keep the patina on the stone. Most supermarket tile cleaning products are simply too strong for a sealed floor so it’s always worth checking the label in detail before buying.
