Details below of a recently laid Ca Pietra Hazlebury Tumbled Limestone tiled floor that retails at £180m2 and should have been stunning however the fitter had ruined it and left it covered in grout haze. The owner of the house in Shipley was unable to get the problem resolved and asked us to take a look.
Removing Grout Haze from Tumbled Limestone Tiles
To restore the appearance of the stone it was necessary to wash the surface in an acid based product called Tile Doctor Grout Clean-Up which is diluted with water and left to dwell on the surface for 1 to 2 minutes before being scrubbed in. Limestone is especially sensitive to acids so you really do have to work fast and wash it off as soon as it’s done its job followed by a thorough rinse with fresh water.
Once the floor was free of the grout it was given a thorough clean with a strong dilution of Tile Doctor Pro-Clean which is a strong alkaline cleaner and sealer remover. This was worked into the floor using a scrubbing pad fitted to a rotary machine and the resultant soiled solution removed with a wet vacuum. After this the floor was given another thorough rinse and then left for two days so it could dry out.
Polishing and Sealing Tumbled Limestone Tiles
With the grout haze removed we were able to bring back the polish on the Limestone using a very fine 3000 grit burnishing pad attached to a rotary machine.
The tiles were then sealed using coats of Tile Doctor Ultra Seal which is a penetrating sealer that soaks into the pores of the stone filling them so dirt can’t penetrate below the surface but without changing the appearance of the stone. It’s highly recommended for Polished Limestone and will provide on-going stain protection.
The resulting transformation was remarkable and as you can image the customer was highly delighted.
Tumbled Limestone Floor Problems Resolved in North West Yorkshire
The photographs below are of an 18m2 Yorkshire Stone floor in the kitchen of a barn conversion in the village of Hebden Bridge. The flagstones which appeared to be various shades of dark grey had lost any colour and vitality they once had, in fact they only seemed to come alive when wet and once dry the natural features and colours of the Yorkshire stone faded away. This was caused by the sealer being worn away allowing dirt to become ingrained in the stone making it difficult to properly clean.
Cleaning Yorkshire Stone
To restore the natural appearance the floor was soaked in a 1:2 dilution of Tile Doctor Pro-Clean and then scrubbed clean using a rotary machine fitted with a black pad. Pro-Clean is an industrial strength alkaline cleaning product that is safe to use on Tile, Stone and Grout; for best results you should let the Pro-Clean dwell on the floor for around ten to fifteen minutes before working it in. The soiled cleaning solution was removed using a wet vacuum and then the whole floor washed down with water and stubborn areas re-treated until I was satisfied that the flagstone and grout was as clean as I could get it.
Sealing Yorkshire Stone
The floor was left to dry overnight and I returned the nexst day to seal the floor first checking it for dampness using a Damp Meter. The flagstones were dry so I then proceeded to seal the floor using four coats of Tile Doctor Seal and Go which adds a nice subtle sheen to natural stone, it also a water based sealer so there’s no smell.
The look of the Yorkshire flagstones was restored and the owner of the house left the following comment on the Tile Doctor feedback system.
Very professional service. Very happy with the results, Ms. E. Parkin
Cleaning Yorkshire Flagstone Tiled Kitchen Floor in Hebden Bridge
These rather dirty but beautiful classic Minster Limestone flagstones had been installed in the Kitchen of a house in the village of Austwick. They were now overdue for a deep clean and polish and so we were asked to do to the work.
Stripping and Polishing Limestone Floor Tiles
To restore the surface of polished stone we use a set of diamond encrusted pads however before starting we gave the floor tiles a general clean with a dilution of Tile Doctor Pro-Clean mainly to clean-up the grout and secondly to remove any loose surface grit. This was rinsed away and removed with a wet vacuum before starting the burnishing process using a rotary scrubbing machine fitted with a coarse diamond encrusted burnishing pad and a little water. The coarse pad strips off dirt and old sealers from the tile and the resulting slurry is then removed using a wet vacuum.
The burnishing pads come in a set of four so once we were done with the coarse pad we moved on to the Medium and then Fine pads again with a little water until the floor was polished. To bring up the polish on the Limestone tiles the last “Very Fine” pad was fitted to the rotary machine and run over the floor to buff it to a nice shine.
Sealing Limestone Floor Tiles
Once the floor was dry we set about sealing it using two coats of Tile Doctor Ultra Seal which is a penetrating sealer that soaks into the pores of the stone filling them so dirt can’t penetrate below the surface. As well as offering excellent protection Ultra Seal doesn’t enhance the stone the stone in anyway giving it a natural look. Once sealing was complete and dry the Limestone tiles were given a final buff with a soft white pad.
I think you will agree that the Limestone tiles now look much better and now that’s it’s been sealed cleaning the floor should be so much easier.
Minster Limestone Flags Cleaned, Polished and Sealed in Yorkshire
This one hundred year old floor needed some serious cleaning; these Orange and Black Victorian tiles installed in the hallway of a period house in Skipton, North Yorkshire had paint, glue and around twenty years of ingrained dirt on them due to previously being covered in carpet.
Restoring Victorian Floor Tiles
To restore the tile surface we used a process we call the Blanket method which involves covering the floor in a mixture of Tile Doctor Remove & Go and Nano Tech Ultra Clean. The whole floor was covered very liberally with the chemical mixture and then sheeted over with polythene and sealed all the way round with water proof tape. There must be a perfect seal so no chemicals can dry out by oxidation and is left over night to soak into the tile.
The next day the polythene was removed in sections and the chemicals were first cleaned off with rags and then rinsed of many times with warm water. The whole floor was then scrubbed with a rotary machine fitted with a black pad and Tile Doctor Pro-Clean mixed 1 to 4 parts warm water to remove all the residue of the chemicals and any dirt. Pro-Clean is an industrial strength cleaning product that is safe to use on Tile, Stone and Grout.
Sealing the Victorian Tiled Floor
The next day I returned and checked the floor for dampness using a Damp Meter which indicated the floor was dry and ready for sealing. Three coats of sealant was used and for Victorian Floor tiles I recommend Tile Doctor Seal and Go which provides a low sheen finish whilst offering great stain protection.
The 100 year old floor now looks almost as new and I think you will agree it has been transformed.
