This beautiful slate floor installed in the Kitchen of a house in Southampton had tons of character but unfortunately years of use had left it looking rather washed out and was overdue for a deep clean and re-seal.
Cleaning Slate Tiled Floors
I set about scrubbing the floor using a hot water dilution of Tile Doctor Pro-Clean Tile and Grout cleaner combined 50:50 with NanoTech UltraClean which adds tiny abrasive particles to the solution to make a more effective cleaning product. The solution was left to dwell on the floor for a while before being scrubbed into the tiles with a rotary machine fitted with a black scrubbing pad; a stiff hand brush was used along the grout lines. The soiled solution was removed using a wet vacuum and floor thoroughly rinsed down with clean water. Pro-Clean works as a stripper as well as a cleaner and so any remaining sealer was also removed using this process, had that been a problem I would of resorted to Tile Doctor Remove and Go which is a much stronger coatings remover.
The soiled cleaning solution was removed using a wet vacuum and this was followed by washing down the area thoroughly with clean water; any stubborn marks were revisited with a repeat of the same process until we were happy the tiles were clean.
Sealing Black Slate Floor Tiles
This process took most of the day so we left the floor to dry overnight and came back the next day to seal it using Tile Doctor Seal and Go, a highly recommended sealer for Slate which provides good stain protection with a low sheen finish, slate is quite porous and it took five coats before it was fully sealed.
I think you will agree the floor is transformed, the natural colours of the slate have come through and the low sheen has given the floor a nice health appearance.
Cleaning and Sealing a Slate Kitchen Tiles in Hampshire
The owners of this house in Southampton called us in to breathe some life back into their slate floor which had become rather dull and had lost its shine. We took a look and could see the previous sealer had been worn down and it was in need of deep clean and re-seal, sealers will wear off over time and once they are gone dirt will start to get trapped in the pores of the tile.
Cleaning the Slate Floor
To remove any remaining sealer and give the floor a deep clean we applied a strong dilution of Tile Doctor Pro-Clean. This was left to dwell on the floor for a while before using a rotary machine fitted with a black scrubbing pad to scrub the floor and get the slate floor really clean. The machine can struggle to reach the grout so it was necessary to get in with a stiff hand brush afterwards and scrub along the grout lines. Once I was satisfied with the condition of the stone floor it was given a wash down with clean water which was removed using a wet vacuum to make sure no chemical was left on the floor as this can affect the sealer later.
Sealing the Slate Floor
Sealing the Slate floor was a straight forward process once the floor was clean and free of any debris etc. The sealer chosen for this floor was Tile Doctor Seal and Go which adds a low sheen finish whilst providing stain protection. Five coats were applied using a paint pad applicator before the floor was fully sealed , the number of coats you need depend on the porosity of the stone and each floor is different and you need to let each coat dry before proceeding to the next.
This Porcelain Terracotta floor had dark grout and the home owner wanted the colour changing to lighten the floor. There are a number of products on the market for this purpose including grout colour pens which are ok for a quick touch up but for a large area like this you really need to use the range recommend by Tile Doctor which not only change the colour but also provides a protective barrier that seals the grout as well ensuring it keeps it appearance well into the future.
Preparing the Grout
Before applying a Grout Colour it’s important to ensure the grout is clean of grease and dirt; Tile Doctor Pro-Clean is a strong alkaline cleaner that’s good for this purpose, for best results you should allow the cleaner to dwell for a while and then get into the grout joints by hand with a stiff brush. Last step is to rinse the floor down with clean water to remove any remaining cleaning product, I recommend the use of a wet vacuum at this point to remove liquids from the floor.
Applying the Grout Colour
Once the grout has dried you can start applying the colourant which is a relatively straightforward process of squeezing the product onto a toothbrush and running it onto the grout. Don’t be tempted to use an old toothbrush for this purpose as it may contaminate the colourant leading to discolouration in the finish. The product sets in a couple of hours so I was able to do the whole floor in a day.
