Multicoloured Slate Kitchen Floor Cleaned and Sealed in Surbiton

I was asked to visit a property in Surbiton to resolve a sealer issue with a Multicoloured Slate tiled floor that was laid in the Kitchen and adjacent dining area. The floor had been sealed professionally two years earlier and was showing signs of wear so the client decided to top up the sealer with three further coats. Unfortunately, the sealer went cloudy and the floor now looked awful.

I visited the property to work out a solution and it occurred to me the only guaranteed way to resolve the problem would be to strip the floor of sealer and re-apply. I worked out a detailed quote for the work which was accepted and a date set for the work to start.

Cleaning and Stripping a Multicoloured Slate Tiled Kitchen Floor

To strip off the sealer the floor was sprayed with a strong dilution of Tile Doctor Remove & Go and this was then left to soak into the Slate for ten minutes. Allowing the product to dwell gives it time to break down the sealer and contaminates. The floor was then scrubbed with a Victor Trojan floor buffer fitted with a black pad and an extra 65kg of weight to increase traction with the stone.

I brought along a colleague to work on this floor and worked backwards so as I scrubbed the floor with the Trojan he followed along with a Hyundai wet vacuum to remove the soiling. Removing the waste like these speeds up the operation allowing areas that need further attention to be dealt with quickly.

Once the sealer was removed attention turned to the Grout which was cleaned with a dilution of Tile Doctor Pro-Clean scrubbed in by hand with a wire brush. The floor was then washed twice with clean water and a black pad to neutralise the floor and remove any trace of product. The wet vacuum was used again here to remove the dirty water.

After a final mop the floor was dried as much as possible with the wet vacuum and then left to dry of naturally overnight.

The next day work started by verifying the Slate was dry using a damp meter which confirmed the floor had dried out. With that confirmation the floor was sealed with Tile Doctor X-Tra Seal buffing off the excess with a white buffing pad afterwards.

Tile Doctor X-Tra 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 an attractive 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 can strip off the sealer protecting the stone from ingrained dirt and so best avoided.

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.
