Maintaining a Slate Tiled Patio at House in Brighton

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!

Badly Finished Slate Patio Restored in Northamptonshire

This customer, who lives in Wollaston, a small village in Northamptonshire, called me to look at the unfortunate condition of her Riven Slate tiled patio. She had hired a builder to install it, but he had neglected to remove the grout haze which had occurred quickly enough, allowing it to set. He was subsequently unable to remove the haze because he had already sealed over it. This had left it looking very unsightly, as you can see in the photo below.

The customer initially contacted me back in December 2016. At that time, I did explain to the customer that the Winter wouldn’t be an ideal time to restore the patio, and that it would be best to carry out the work in the Spring. However, she was so unhappy with the appearance of the patio and – knowing she had guests coming over for Christmas – wanted something to be done to improve the condition of the tiles as soon as possible.

It was agreed that I would immediately carry out the removal of the old sealer and the grout haze beneath, but leave the re-sealing until the Spring of the following year when the weather was dry. The customer understood that when I returned in the Spring, the patio would require another light clean and brush to prepare it for sealing.

To put the customer’s mind at rest somewhat, I carried out a test clean on one slab of the patio using Tile Doctor impregnating, colour intensifying sealer, known as Colour Grow. This darkened the tile and provided a natural look finish, which was preferred by the customer. I also returned to the property several days later to carry out a water repellency test, but as you can see from the photo below, the rain beat me to it. Thankfully, the repellency test had positive results.

I was then able to begin the cleaning process.

Cleaning and Sealing a Riven Slate Tiled Patio

To begin, I removed the old sealer using a strong mix of Tile Doctor Remove & Go, which is a stripper and cleaner. This product was scrubbed into the tiles with a rotary brush machine. Net, I rinsed away the resulting slurry and soaked up the water with a wet vax machine.

This initial clean exposed the true extent of the grout haze – it was over all every tile! My next course of action was therefore to remove this using Tile Doctor Acid Gel, which is a gel cleaner specially formulated to neutralise grout haze. This was allowed to dwell for a short period before I brushed it in.

Following this, I gave the whole area a second brush with a small amount of water, before using a wet vax machine once again to make sure all cleaning chemicals were removed. I used the customer’s hosepipe to rinse down the entire patio as there was good drainage.

I allowed the tiles to dry out naturally, before waited for a dry day in April this year to return to the property. During this day, I sealed the entire area with Tile Doctor Colour Grow sealer to really deepen the colour in the stone and provide the whole patio long-lasting protection against the elements.

The customer was exceptionally happy to have the patio restored to perfect condition. I’m sure she’ll make great use of it over the Summer!
