I recently visited a client living in the market town of Woodstock in Oxfordshire to rejuvenate a fantastic multi-coloured Slate floor that had been hidden under several years’ worth of dirt in their kitchen. Slate is a typically hard-wearing tile used for flooring high traffic areas of houses and public buildings but does need sealing to bring out its best features and in this case the sealer had long since worn off and dirt had become ingrained in the stone.
Cleaning a dirty Slate tiled floor
My first task in the cleaning process was to mix a strong solution of Tile Doctor Pro-Clean, which is a strong alkaline cleaner safe to use on Tile and Stone, and NanoTech HBU (Heavy Build-up Remover), which is a particularly powerful product that uses nano-sized particles to tackle muck in areas of the stone where typical cleaners simply can’t reach. I spread this solution across the floor and left it to seep into the stone, to get underneath and lift out the ingrained dirt.
After allowing the solution adequate time to dwell, I scrubbed the floor with a carbon brush to gradually reveal the fantastic natural colours of the Slate hidden beneath. Following this, I rinsed the entire floor several times with clean water, before soaking up the resulting soiled residue with a wet vacuum.
The next part of the cleaning process entailed paying particular attention to the grout lines. I used Tile Doctor Grout Clean-Up to scrub the grout lines and also to treat a small amount of efflorescence. The resulting residue was promptly extracted with the wet vacuum and I finished by giving the whole floor a rinse with Tile Doctor pH Neutral Tile Cleaner. This is a day to day tile cleaning product which is recommended for stone floors, many supermarket tile cleaning products are only suitable for ceramic tiles due to their acidic formula and can damage a floor over years of use so you should always read the label. I then left the floor to dry completely overnight.
Sealing a Slate tiled floor
On day two, the Slate tiled floor was dry and ready to seal. The floor had to be completely dry, as any excess moisture has the potential to the damage the performance of the sealer. Since my client had specifically requested a matte finish, I opted to use Tile Doctor Colour Grow. Colour Grow is an impregnating sealer that provides durable surface protection from within while also enhancing all of the natural mineral shades.
My client was very pleased with the results, particularly as they hadn’t realised they had such a great looking floor in their house when they had first purchased it!
