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.

How to Remove Screed and Bitumen from Stone Floors

The owner of this Flagstone floor at a property in Carnforth was told by a damp specialist to remove the carpet and underlay and have the floor taken out and skipped. Then to install new hardcore and concrete put in place but with a Damp Proof Membrane installed in between, then once fully cured (four weeks at least) they could have a new carpet, tile or wood floor etc. installed. All good advice, however, the owner of the house wanted to keep as many original features as possible and wasn’t keen on the proposal.

Looking for an alternative solution they reached out to Tile Doctor and so I went over to take a look. After surveying the floor, I came up with a completely different solution which involved milling the stone with coarse abrasive pads to remove the screed and bitumen and then resurface with diamond encrusted burnishing pads of medium and fine grits which would result in a smooth finish. Not only would this be much easier to clean going forward it would also be much more attractive, especially once sealed.

Happy with our alternative we arranged a date to come and do the work which would take three days, two days to prepare the floor and a third to apply a sealer.

Milling a floor is arduous work and requires the use of a heavy rotary machine that can apply weight onto the stone so the milling pads can really get a bite into the surface. Because of this I roped in a colleague to help take some of the strain. Some of the areas of bitumen and screed were so prominent we used an SDS hammer action drill with a flat bit to chisel them off first, this can leave a few marks in the stone which we then level out with the milling pads starting with a 50 grit and go all the way up to a 400 grit.

We used a lot of water during this process to help lubricate the abrasive action of the milling pads, this also helps to rinse off the soil that is created, all of which is extracted with a wet vacuum.

Next step is to give the floor an acid rinse with Tile Doctor Grout Clean-Up which is designed to neutralise any alkaline salts in the stone that could result in efflorescence later.

With the floor cleaned up the last step was to re-point between the Flagstones using a breathable pointing product called GFtK 800.

Sealing a Flagstone Tiled Ground Floor

Sealing was the next step however the floor was still quite damp after the initial renovation, so it was left for a few days to dry out first.

We selected a fully breathable sealer for this floor, this is an important requirement for a floor with no damp proof membrane as it will allow moisture to rise through the flagstone and evaporate at the surface. The concrete screed and bitumen covering will have prevented this previously which is dangerous as a build up of moisture in the stone can lead to it crumbling and you risk moisture reaching out to the walls where it can lead to rising damp. 

Tile Doctor has three breathable sealers to choose from and in this case the customer decided to go with Tile Doctor Colour Grow which is an impregnating sealer that protects from within and enhances the natural colours in the stone.

The floor was completely transformed by the end of the third day, you would not have known it was the same floor. It was now clear of all the previous coverings and now looked like a characterful old Flagstone floor should.

Before leaving I recommended, they use Tile Doctor Neutral Cleaner for everyday cleaning, being pH neutral it won’t prematurely erode the sealer allowing it to work for longer. I also advised that it’s possible that parts of the stone may go a shade darker in winter and a shade lighter in summer due to the moisture rising through the floor.

How to Deep Clean and Renovate a Travertine Tiled Floor

The client in Bishops Cleave contacted me as she was so frustrated with her Travertine tiled floor she was thinking of having it taken up. The tiles had been laid throughout the Hallway and into the Kitchen many years prior. The appearance of the floor had slowly deteriorated over the years to the extent that she was now having real trouble getting it clean.

I arranged to visit the property in Bishops Cleave which is a small village between Cheltenham and Tewkesbury. The floor was indeed in need of attention, the sealant had clearly broken down and dirt had become ingrained in the pores of the stone. I discussed with the client what could be done to restore the appearance and demonstrated the cleaning process on part of the floor. She was thrilled with the result and about the possibility of getting the floor restored. Better still she would avoid all the disruption of relaying the floor and of course the cost. We agreed a price to carry out the work and I arranged a suitable date to return and complete the work which would take two days.

Renovating a Dirty Travertine Tiled Floor

Returning to the property the first task was to protect the kitchen units and wooden stairs with masking film. I then started cleaning with floor with a coarse 400-grit Diamond burnishing pad fitted to a rotary floor buffer using water to lubricate the abrasive process. The pad is run over each tile a few times and then once the section is completed the floor is rinsed with more water and fine slurry extracted with a wet vacuum.

This process is then repeated with the medium 800-grit pad and fine 1500 grit pads, again rinsing with water and extracting after each pad with the wet vacuum. it’s a slow process but burnishing the floor in this opens the pores in the stone so the dirt can be removed and then closes them up again so restore its appearance.

The grout lines were quite heavily soiled with dirt, so my next task was to scrub them with a strong dilution of Tile Doctor Pro-Clean. The area was then again rinsed, and the soil extracted leaving the floor to dry off overnight.

Returning the following morning, I then spray burnished the floor with a 3000-grit polishing pad to remove any residue that might have been left behind and to further bring up the polished appearance of the Travertine.

This final pad is applied dry with only a little water, so it leaves the floor nice and dry and ready for sealing. For the sealer I had selected Tile Doctor Ultra Seal which is a no-sheen, penetrating sealer which doesn’t change the appearance of the stone leaving a natural finish. It is formulated to provide maximum stain protection, so is particularly good in kitchens. It is also an excellent grout sealer. The sealer was applied and left to dry for an hour then buffed again with the 3000-grit pad. This gave the floor a lovely finish and the natural beauty of the Travertine was at last able to shine through. I was very pleased with this restoration.

The client was delighted and very pleased the she had contacted Tile Doctor, the floor looked great. She was very happy she had not needed to replace the floor. I suggested to her to maintain the floor she should use Tile Doctor Stone Soap which is a pH balanced product which you dilute. It will ensure the seal is not compromised and will keep the floor in great condition.

Best Method to Restore a Terrazzo Patio

This was an unusual request to bring back to life a Terrazzo porch entrance that was installed by the customers father many years earlier at a house in Newport. The installation resembled very colourful crazy paving which was very popular in the 70's but if you look closely you can see it has more in common with Terrazzo due to the inlaid stone which has been ground down within the concrete base.

Years of exposure to the elements had left much of the stone and concrete discoloured and almost black in places. I discussed with the client how we would be able to clean the area and we agreed a price for the work which would take a day to complete assuming the weather held. Being an external job, I would need a warm day before coming back, this would ensure it dried easily.

Thankfully for once the forecast was correct and the weather was good on the day, we had booked in to complete the job. To restore the appearance first I used a set of diamond burnishing pads with water to grind off the dirt and refine the appearance of the stone and aggregate. I used a variety of pads with different grades of grit to ensure the floor was as clean as possible rinsing the slurry off the floor after each pad. The transformation was dramatic. The patio was then rinsed with water to remove the slurry that was generated, and I used a wet vacuum to extract it.

This process took much of the morning, it made a pleasant change to work outside in the fresh air, most of our jobs tend to be indoors. After a final rinse I left the porch to dry out in the sun over lunch and came back in the afternoon to seal.

First, I checked the floor had dried out with a moisture meter, it was within the acceptable levels, so had the green light to processed and seal the floor. Since cleaning it really was starting to look like a nice feature.

To seal the patio, I used a couple of coats of Tile Doctor Colour Grow which works well externally as it copes with damp conditions. It’s a colour intensifying impregnating sealer that provides durable protection to the surface as well as allowing the floor to breath. You can see from the photograph below how just how well Colour Grow improved the colours in the stone. Once I had finished it looked like a new installation.

The client was over the moon I had managed to get the area looking this good. He said he could remember when it was laid, and his dad would be very proud of it now. It had definitely stood the test of time.
