How to Restore Colour and Structure to Tired Flagstone Flooring

A customer from Ulverston was nearing the end of a house refurbishment and got in touch regarding the renovation of a Flagstone floor. A lot of contractors had been through the property and the stone was not looking its best. Happy to assist I arranged to visit the property and provide advice on its restoration.

I went over to survey the floor and could see it was suffering from heavy ground-in soiling. The stone had lost its colour and now looked dull and lifeless; the grout was also heavily soiled with ingrained dirt. We discussed the floor in detail and I recommended a deep clean to remove all the dirt and then applying a sealer to restore colour to the stone and prevent ingrained dirt.

After measuring up I worked out a detailed quote and emailed it across to the customer for their review. Happy with quote I got the go ahead to restore the floor and agreed a date.

Deep Cleaning a Tired Flagstone Floor

To get the stone clean it was sprayed with a strong dilution of Tile Doctor Pro-Clean and this was left to soak in for a good fifteen minutes to give it time to start breaking down the ingrained dirt. The floor was then scrubbed with a rotary machine fitted with a coarse carborundum brush which lifts the dirt out of the stone and grout. The soiling was then rinsed off the floor and extracted with a wet vacuum.

To further clean the Flagstones and strip off old sealers and remaining surface residues the floor was further treated with a strong dilution of Tile Doctor Remove and Go. This time the solution was scrubbed into the stone using a coarse 200-grit diamond burnishing pad to refine the appearance of the stone.

After rinsing and extracting again the stone was given an acid rinse using Tile Doctor Acid Gel. This neutralises the stone after the use of alkaline cleaners and further cleans the stone to remove grout smears and old mineral deposits to further refine the surface, improving clarity and tone within the stone.

After a final review of the stone to spot clean any stubborn areas, it was given another rinse and dried as much as possible using the wet vacuum.

Sealing a Flagstone Floor

The floor was left to dry out overnight and work resumed the next day to finish the stone with the application of a sealer. First however the floor was checked for moisture, applying sealer to damp stone can result in a patchy appearance so best avoided.

The results were fine so work started to apply the first of what would be two coats of Tile Doctor Colour Grow. This sealer is an impregnator that soaks in the stone adding protection from within, this ensures dirt remains on the surface where it can be easily cleaned away. Another feature of Colour Grow, as its name suggests, is to enhance and deepen the colour and features in the stone.

 

Once complete the flagstones were restored to a rich, natural finish with improved colour depth and a far more uniform appearance. The surface is now protected and significantly easier to maintain.

 

For aftercare I recommended Tile Doctor Neutral Tile Cleaner which will clean the floor without impacting the sealer which can be a problem with many of the stronger products you find in supermarkets.

Stained Flagstone Floor Deep Cleaned in Gloucestershire

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.

Cleaning a traditional Yorkshire Stone internal 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.

Sealing a traditional Yorkshire Stone internal floor

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.
