Except for general cleaning this multi-coloured slate floor had not been professionally cleaned since installation eleven years prior. Any sealer that had once been applied to the slate had long since worn off and dirt was now ingrained in the pores of the stone causing it to look dull and un-attractive. The property was in the lovely town of Staines Upon Thames, obviously situated on the banks of the River Thames and a popular place to live for London commuters.
I visited site to take a closer look at the floor and provide the client with an accurate price for renovating the stone. It turns out that the client had used all sorts of different household cleaners in an attempt to get the floor clean. Unfortunately, they were probably making the situation worse as these strong cleaning products would have actually stripped the sealant off the stone leaving it open to dirt. I carried out a test clean for them and they were very pleased to see how the floor could look. We agreed a price for the work and arranged a suitable date to carry out the work.
Cleaning a Multi-Coloured Slate Tiled Kitchen Floor
My first task was to strip off what was left of the old sealer and deep clean the stone using a dilution of Tile Doctor Remove and Go mixed 50:50 with Tile Doctor Pro-Clean. This powerful cocktail was applied to the floor and left to soak in for ten minutes before being scrubbed in using a rotary machine fitted with a black scrubbing pad.
The grout was hand scrubbed using more of the cleaning solution along the grout lines until I was happy the floor was as clean as it possibly could be. The floor was rinsed with water and the soil extracted by using the wet vacuum.
Once the floor was clear the Slate was inspected, and any stubborn areas were spot treated using the same process as before. After a final rinse and extraction, the floor was dried as much as possible using the wet vacuum and left to dry off overnight.
Sealing a Multi-Coloured Slate Tiled Kitchen Floor
I came back the next day and checked the moisture levels of the tiles using a damp meter. The floor had dried well so I had a green light for applying a new sealer. For this I used four Coats of Tile Doctor Seal and Go, allowing each coat to dry before applying the next. This product works really well on Slate and gave the tiles a nice sheen finish, the fresh sealer will also make maintenance cleaning far easier in the future.
The client was very happy with the result, the floor now looks great and the natural colours of the stone is so much more evident. For aftercare I recommended they throw away all those supermarket products and use Tile Doctor Neutral Tile Cleaner which is a pH neutral product that won’t prematurely erode the new sealer with use.
When cleaning tiles with a mop we recommend using two buckets, one containing a neutral pH cleaning fluid such as Tile Doctor Neutral Tile Cleaner or Stone Soap and the second where you rinse your mop afterwards, otherwise you will contaminate your cleaning fluid with dirt every time you rinse.
