Slate Tile Cleaning

Welcome to my Work History archive where you will find detailed examples of the cleaning and renovation of Slate flooring carried out in South West London

Cleaning and Renovating Slate Floors

Slate is a very popular floor and wall tile due to its low porosity; there are many varieties and textures of Slate available as such Tile Doctor has spent many years researching the best cleaning and sealing methods and products. The semi-riven tile is particularly easier to maintain compared to the rough textured Slate commonly available due to its cheaper quarrying cost.

Porosity however small, is the main issue when maintaining Stone floors as dirt can easily become trapped in the pores and once that happens it becomes very difficult to clean. The solution is to prevent the ingress of dirt in the stone by applying a sealer such as Tile Doctor Seal and Go which works very well on Slate. However sealers do wear down with use and the application of unsuitable cleaning products, and so unless regularly maintained the floor will need to be stripped, deep cleaned and then resealed again every three to five years.

Below you will find detailed examples of work we have carried out in the past, it should give you some idea of what’s involved and what can be achieved with the right techniques and products.


Black Slate Kitchen Floor Renovation Richmond London

Cleaning and Sealing a Black Slate Kitchen Floor in Richmond KT2

This is a black slate floor in Richmond that had been stripped of its natural oils and sealer due to the client using a steam mop repeatedly over the years. The floor also had missing grout that needed replacing before cleaning could commence.

The flat wasn’t on the ground floor so there was a concern that the missing grout may result in water getting under the tile causing damage to the floor and not to mention the ceiling of the property below.

Repairing Grout and Cleaning a Black Slate Tiled Kitchen Floor

The first thing I did was to protect all the Kitchen units by covering them in a drop cloth. Once that was done work started on the grout lines which involved raking out the loose grout and replacing with a fast-setting grout in matching grey.

Once the grout had set attention moved onto to cleaning the Black Slate tiles which without the protection of a sealer contained a lot of ingrained dirt. To clean the tiles a medium strength dilution of Tile Doctor Pro-Clean was sprayed onto the floor and left to soak in for ten minutes. The floor was then scrubbed with a carbide brush fitted to a handheld De Walt polishing machine, I then used a Hyundai wet vacuum to hoover up the water and sediment that had come up during cleaning.

Next, I scrubbed the grout with a mixture of Tile Doctor Pro-Clean, water and a wire brush. To finish I gave the tiles a light acid wash using Tile Doctor Grout Clean-Up diluted with water. I vacuumed this off, washed the tiles down with water and gave it a final vacuum to get it as dry as possible.

The floor was then left to dry out, leaving a floor dryer with the client to run for a few hours more before turning off and leaving the floor overnight.

On my return, after establishing the stone had completely dried out, I applied two coats of Tile Doctor X-Tra Seal. The sealer was worked into the floor with a cloth using small amounts at a time polishing off the excess as I went along. It’s important to do this with this sealer otherwise it can get slightly tacky if too much is left on the surface.

Tile Doctor Xtra Seal was chosen for this floor as it’s an oil-based sealer and that add structure to the stone and works well to bring out its features and colour. It’s also extremely durable and leaves a nice low satin finish.

The floor was transformed by the work and my client was extremely pleased with the result. For aftercare I recommended the use if Tile Doctor Neutral Tile Cleaner, it has a pH neutral formula that won’t impact the newly applied sealer. Typical household cleaning products tend to be bleach based and will strip off the sealer protecting the stone from ingrained dirt and so best avoided.

Black Slate Kitchen Floor Renovation Tooting

Black Slate Tiled Kitchen Floor Renovated in Tooting

The photos below are of a Black Slate Kitchen floor at a property in Tooting SW17, which as you can see had lost all its colour and character. I went over to survey the floor and discussed a renovation plan with the owner.

One of the problems was the grout which like the tile hadn’t faired very well over the years and being in the Kitchen was subject to staining. I explained that like all stone floors the Slate needed to be sealed in order to keep the dirt out of its pores and keep it looking its best. Sealers however wear down with use and in this case the floor hadn’t been deep cleaned and sealed for some time.

I costed out a renovation plan which included deep cleaning the Slate tile removing any remaining sealer in the process, renovating the grout, and then re-sealing the whole floor to bring back the appearance of the stone and protect it going forward. Happy with the quote we agreed a date to start the work.

Deep Cleaning a Natural Black Slate Tiled Kitchen Floor

Normally I would use a Tile Doctor product called Remove and Go to remove the sealer, however in this case testing had shown that what was left of the sealer could be removed with Pro-Clean which is also our go to Tile and Grout Cleaner.

I used a strong dilution of Pro-Clean to do this, spraying it onto the floor and leaving it to soak in for ten minutes and break down the dirt etc. Then using a black scrubbing pad fitted to a heavy rotary buffer machine it was worked into the Slate to release the dirt and old sealer. The floor was then rinsed with water and the soiling extracted with a wet vacuum.

The pads can struggle to get into the corners and edges of the floor and the recesses of the grout line. So, to complete the cleaning a handheld scrubbing brush was used and a wire brush run along the grout lines, again with more Tile Doctor Pro-Clean. After another rinse and extraction with the wet vacuum the floor was left to dry aided with a couple of floor blowers.

Grout Colouring and Sealing Black Slate Tiled Kitchen Floor

Once dry the grout was coloured with a Black Tile Doctor grout colourant which is basically painted onto the grout with a small brush and any excess wiped off the tile. This grout colourant gives the grout a uniform appearance and adds an impenetrable barrier over the grout sealing it in and keeping it safe from further staining. Keeping grout clean in a kitchen is always a problem so the colourant will protect it and make it very easy to clean.

The last step was to seal the Slate for which I used Tile Doctor X-Tra Seal. This was chosen because it’s an impregnating oil-based sealer that will restore the beautiful dark colour in the stone. Impregnators work by occupying the tiny pores in the stone thereby forcing dirt to remain on the surface where they can easily be cleaned away.

In the subject of maintenance cleaning, I recommend the use of Tile Doctor Neutral Tile Cleaner which is a gentle but effective cleaner that won’t harm the sealer. Many of the floor cleaning products you find in supermarkets etc are not for use on sealed stone, they contain strong chemicals such as bleach etc which will strip off the sealer prematurely so best avoided.
