I recently helped a homeowner from my home town of Dursley who got in touch about her kitchen Flagstone floor. The problem revolved around an accident she had with raspberries which had stained the flagstones and the problem became compounded when a house hold clearing product was applied neat to clean up the mess. If you follow any of our Tile Doctor blogs, you will know that using strong household cleaning products can damage the sealer and, in this case, it had left white marks on the floor.
I called round to the property to survey the floor as was surprised to find out that the floor had been cleaned and sealed only four months prior by another company. I don’t like to comment on other people’s work, but I found the grout lines and flagstones were still badly ingrained with dirt, so it wasn’t a through job.
I completed by survey and demonstrated the process I would follow to resolve the issues on one of the flagstone tiles. She could not believe the difference I was able to make and booked me in straight away to restore the entire floor.

My first task was to protect the wooden kitchen units from splashing that can happen when cleaning the floor. Once that was done, I set about stripping the sealer from the floor and deep cleaning the tile and grout with a strong dilution of Tile Doctor Pro-Clean. Pro-Clean is a concentrated, multi-purpose high-alkaline cleaner, stripper and degreaser which is safe to use on all types of tile, stone and grout including natural stone.
Working in sections across the Kitchen and adjacent dining room I diluted one part Pro-Clean to two parts water and mopped it onto the flagstones and grout where I left it to soak in for roughly fifteen minutes. Then using a rotary floor buffer fitted with a black scrubbing pad I scrubbed the solution into the floor into the old sealer and trapped dirt came away turning the cleaning fluid black in the process. The soil was then rinsed off with water and then extracted with a powerful 3,000 watt wet and dry vacuum. This process was repeated until I was satisfied the floor was clean and I ran a stiff grout brush along the grout lines to ensure they also received a good scrub. After I was satisfied the section was clean it was rinsed thoroughly with water to neutralise the floor and remove any trace of product and then dried with the wet and dry vacuum.
The cleaning process took up the whole day, but the flagstones would need to be dry before sealing so after giving the owner an update I left the floor for two days, so it could dry out thoroughly.

On my return I tested the floor was dry in multiple places with a damp meter to ensure it was ready to be sealed. The readings showed that the wet and dry vacuum had done a good job in removing the moisture, so all was well. To seal I applied several coats of Tile Doctor Seal and Go allowing each coat to dry before applying the next however with such a large area to cover I was able to work in sections around the floor.
Seal and Go works really well on Flagstones and leaves a very appealing sheen finish, also being water based it doesn’t leave a smell as it dries.
The results were amazing, and the customer thanked me for making such a massive improvement on her floor. Before leaving I made sure to discuss after-care and to avoid the use of hash cleaning products.
