This customer had recently moved into a property in Abingdon and got in touch about having the coloured Slate floor tiles in the kitchen cleaned and sealed. There was a big variation in appearance from one end of the kitchen to the other and they had a hunch that the Slate had a lot more colours in it than they could see!
I called in to survey the floor and could see that the main issue was the usual problem of the sealer wearing down in the high traffic areas allowing dirt to penetrate and build-up in the pores of the stone. I ran some tests on the tiles and carried out a test clean, the difference in the stone and grout was immediate, and the customer was happy to go ahead and have the whole floor done. We arranged to carry out the work later that month.
Cleaning a Coloured Slate Tiled Kitchen Floor
To clean the floor, I first spread a dilution of Tile Doctor Pro-Clean over a section of the slate tiles. It was then left to soak into the pores of the stone for ten minutes before working it into the slate with a mono rotary floor machine fitted with a black scrubbing pad. I find the pad works well on tiles but can struggle in the recesses of the grout line, so I followed this up by running a stiff brush along the grout lines to get them clean as possible.
After scrubbing the floor in this manner, the dirt was released from the pores of the stone into the cleaning solution and I was then able to extract the resulting slurry from the floor using a wet vacuum. I worked in sections like this until the whole floor was completed. It was surprising how much dirt had been lifted and the Slate floor was a different colour after I had finished.
I then rinsed the floor with water a couple of times and then followed up by scrubbing the floor with Tile Doctor Grout Clean-Up which is an acidic product which cleans the stone further and removes any mineral deposits including grout smears. Being an acidic product, it also counters the alkalinity of Tile Doctor Pro Clean effectively leaving the floor with a neutral pH. I rinsed the floor a couple of times with water and then mopped the floor with Tile Doctor Neutral Floor Cleaner.
That completed the first day, I left for the evening and the floor was left to dry overnight.
Sealing a Coloured Slate Tiled Kitchen Floor
I returned on day two and tested the floor using the moisture meter to make sure it was dry. The readings were good, and I was satisfied it was dry enough to take a sealer. To seal the floor, I applied Tile Doctor Seal & Go which leaves the floor with a sheen finish that the customer wanted. The Slate was quite porous, so it took seven coats to fully seal the floor which took some time and you have to allow for each coat to dry before applying the next.
The floor was transformed by the time I had finished, and you can see from the after picture how clean the grout is and how the lovely Copper tones in the stone were now evident; the natural variations in colour were now as they should be. Clearly their hunch had been right!
The customer was very happy and left the following feedback which is always gratefully received as much of our work comes from recommendations.
“Very happy with the service we received. Barry did an excellent job restoring our floor and we wouldn’t hesitate to recommend him.”
