This Yorkshire flagstone floor was about 20m2 in size and was well overdue a deep clean, additionally a lot of the pointing was loose or missing which would need to be resolved. The location of this job was at a house in Haworth village which is situated at the edge of the Pennine moors in West Yorkshire, the area is known as Bronte country after the famous Bronte sisters who lived here in the local parsonage in the 19th century.
Cleaning Yorkshire Stone
To deep clean the floor the sandstone flagstones were covered in a 1:3 dilution of Tile Doctor Pro-Clean which was left to dwell and soak into the stone for 15 minutes before being scrubbed clean using a rotary machine fitted with a black pad. The now dirty cleaning solution was then removed using a wet vacuum and then the whole floor washed down with water and stubborn areas re-treated until I was satisfied.
The next step was to rake out the loose pointing and re-point with a matching grey flexible wide joint grout. This is the advantage of using a Tile Doctor to work on your tiled floors as were not just a cleaning company.
Sealing Yorkshire Stone
The floor was left to dry overnight and I returned the next 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.
You can see from the photo that as well as protecting the floor the sealer adds to the appearance of the tiles and brings out the natural colours that were not visible earlier.
