Here we have an interesting situation in which an old Flagstone tiled floor had been salvaged from a cottage approximately 30 years ago and subsequently reinstalled at a house in Ledbury, a small market town which lies to the west of the Malvern hills in the North of Gloucestershire. Since being reinstalled, the Flagstone tiles had been barely touched in terms of maintenance for three decades and so the stone and grout were naturally in need of a deep clean and seal!
Cleaning a Dirty Flagstone Tiled Floor
My first job in the cleaning process was to distribute a mixed solution of two cleaning products across the floor. These products were Tile Doctor Remove and Go, which is a multi-purpose stripper designed to remove old coatings and sealers, as well as any adhesive and paint stains, and Tile Doctor NanoTech HBU, a powerful cleaner which utilises nano-sized particles to penetrate difficult-to-reach areas of the stone to eliminate deep lying dirt and stains.
This potent cleaning solution was left to dwell on the surface of the floor for 45 minutes before being worked deep into the stone with a poly brush fitted to a buffing machine. The resultant cleaning slurry was then hoovered up with wet-and-dry vacuum. Next, the floor was rinsed and cleaned with just clean water and the slurry was once again hoovered up.
When satisfied with the result of the cleaning process, I rinsed the floor for a final time with fresh water, hoovered up as much moisture as possible with a wet vacuum and left the stone to dry off fully overnight.
Sealing a Flagstone Tiled Floor
On arrival at the property the following day, I checked the floor for dampness with my damp meter. The test proved that no excess moisture was present, so I proceeded to give the Flagstone a fresh seal.
With regards to sealer choice, the customer had requested a natural-looking matte finish to match in with the rustic characteristics of the Flagstone, so I used Tile Doctor Colour Grow – which provides exactly that. Colour Grow is a durable impregnating sealer that also enhances the natural shades in the stone to really bring the whole floor back to life. Roughly an hour was left between the application of each coating of sealer to allow the floor dry before applying the next.
