Brighton is a great location to work with a huge variety of property styles and tile installation but being such a popular location parking can be an issue. We need to park our van physically close to the property so we can make use of our powerful Truck mounted cleaning system that weighs in at 3/4 of a tonne! It’s a really clever system that uses water under very high pressure to clean the stone whilst at the same time recovering the waste back to a storage tank in the van making it a very clean operation even in the most awkward conditions.
I thought I would mention this first as I was asked to deep clean and seal the lower ground level Slate tiled courtyard patio at this property in Brighton which was located down a small side street where people rarely moved their vehicles due to lack of spaces available. Fortunately I was aware of the issue and managed to overcome it by arranging a parking suspension with Brighton and Hove City Council allowing me to park my van.
This patio was open to the elements and was also used by the owner’s dog. Further due to its inaccessibility it had never been cleaned apart from with the general hosepipe sprayer. Any kind of porous stone will over time become dirty and stained if the sealer is not maintained, sealers do fail eventually and usually in the highest traffic areas first where they become worn down the most.
Deep Cleaning Dirty Slate Patio
The first job was to pressure clean the entire area using the truck mounted system I mentioned earlier, it works well on patios removing all sorts of detritus that can build up over time.
With patio now clear I was able to see the condition of the slate which showed grout smears on the surface from installation as some stubborn staining that the pressure treatment had been unable to shift. To resolve this I mixed up a batch of Tile Doctor Cleaning Agent Oxy Gel together with Tile Doctor Acid Gel and applied it to all the problem areas. Liquids have a tendency to run (patios have a gentle slope to allow for rain run off) whereas Gel’s remain in place so they dwell on the problem areas longer and really get to work. I left the mixture in place for a short while before scrubbing it in with a stiff brush and then extracted it using truck mount system. The water from the truck mount also neutralised the acid which is important as you shouldn’t leave acid on natural stone for too long.
Sealing a Slate Patio
Fortunately there was no rain that night and being August also quite warm so I was pleased to find the Slate had tried off fully by the next day when we returned to seal it. To be certain however I ran some quick damp tests to check that the floor was completely dry and ready to be sealed. Once satisfied, I applied a couple of coats of Tile Doctor Colour Grow which works really well on Slate giving it that much needed protection against dirt and stains, along with a full lustre finish that enhances the character of the floor.
The client was elated both with the result and even more so after we explained how to maintain the look of the tiles with having a doggy in the house!
