I recently visited a customer living in the village of Ravensthorpe, just outside Northampton to rejuvenate a 15-year-old multi coloured Chinese riven slate floor that needed a deep professional clean. Slate is a hard-wearing tile used for flooring high traffic areas but does need sealing to bring out its best features. In this case the sealer had long since worn off and dirt had become ingrained in the stone making it difficult to clean effectively.
We discussed the client’s requirements and the cleaning process I planned to follow to rejuvenate the floor. I had to check on availability, so I e-mailed over a quote and some dates later that day. They were happy with my proposal and agreed for the work to be done whilst the customers were on holiday.
Cleaning Riven Multi Coloured Slate Tiles
My first task was to test a small area to determine which products would give the best results. In this case, I decided to start with a strong dilution of Tile Doctor Remove and Go which is a strong alkaline cleaner/coatings remover that’s safe to use on Tile and Stone. I spread this solution across a section of the floor and left it to seep into the pores of the stone and lift out the ingrained dirt.
After allowing the solution adequate time to dwell, I scrubbed the slate with a carbon brush fitted to a rotary machine to gradually reveal the fantastic natural colours of the Slate hidden beneath the dirt. Happy with my choice of cleaning product I repeated this process in sections until it had been carried out throughout the entire area. 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 attention to the grout lines which were scrubbed using Tile Doctor Grout Clean-Up. 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. However, I always leave my clients with a complimentary bottle of a suitable Tile Doctor product to maintain their floors.
Sealing Riven Multi Coloured Slate Tiles
The floor was left to dry off overnight and I returned on the second day to seal the floor. Before starting I checked the floor was dry using a damp meter which confirmed the Slate was dry and ready to seal. The floor must be completely dry before sealing as any excess moisture has the potential to the damage the performance of the sealer. Since my client had specifically requested a silk finish, I opted to use Tile Doctor Seal and Go which dries to leave a lovely subtle sheen that really enhances the look of the stone. Five coats were applied to ensure a good hard-wearing protection.
My client was very pleased with the results, particularly as they hadn’t realised how much colour it had lost over the years and left the following feedback on our website.
”I despaired of having a clean-looking floor again. Phil Vissian assured me that intensive deep cleaning and resealing could restore our fifteen year old, subtly coloured, Chinese riven slate kitchen floor. He has done a fantastic job. Looks like new, and I shall book Phil for an annual professional clean, so that it never gets as bad again.” Sally M, Northampton
