Deep Cleaning and Sealing a Beautiful Slate Tiled Kitchen Floor in Spencer’s Wood


Slate tiles do look incredible but like any natural stone you really need to maintain the sealer if you want them to stay that way. Unfortunately it’s usually the case that the sealer wears off overtime especially in the high foot traffic areas such as Kitchens and within a few years the tiles become dull with ingrained dirt.

This process happens so gradually it goes un-noticed until the floor becomes difficult to keep clean and a decision is made to have it sorted out. This was certainly the case with this Semi Riven Multicoloured Slate tiled kitchen floor at a house in the Berkshire village of Spencer’s Wood. The floor had been installed about fifteen years prior and over the years the Slate had become soiled to the point where domestic cleaners weren’t having any effect.

Cleaning Dirty Slate Kitchen Tiles

To begin the restoration I soaked the tiles in a strong dilution of Tile Doctor Remove and Go and left it to dwell for about twenty minutes re-applying extra solution when it had dried. Remove and Go is our go to product for removing old coatings such as in this case sealers, although much of the old sealer had worn off it was still present in the less busy areas of the floor and to get an even final result I needed to ensure all of it was removed. Once the old sealer had started to weaken I agitated the product using a black pad fitted to a rotary buffing machine. The rotary pad struggles to reach into the recesses of the grout lines so I also made sure to scrub the solution into the grout with a grout brush.

I suspect there were multiple layers of sealer on this floor that had been applied over the years as some areas were proving particularly stubborn. Something stronger was going to be needed particularly in the grout lines. So I applied Tile Doctor HBU remover; HBU stands for Heavy Build-Up and allowed this to dwell for thirty minutes while I cleaned other areas.

Once I was satisfied that the Slate and the Grout was clean and clear of old sealers I gave the whole floor a rinse with water using a wet extraction machine. One the soiled cleaning solutions were removed you could really see the difference that the combination of cleaning products had made.

The final step in the cleaning process was to give the floor an Acid Wash using a mild solution of Grout Clean-up which removes any surface grout (aka grout smears) and other mineral deposits from the slate to ensure they true beauty of the stone will be visible. Once this was removed the whole floor was rinsed with water to remove any trace of product and then dried as much as possible. After a final inspection the floor was left overnight to dry off fully.

Sealing Slate Kitchen Tiles

Returning to the property the next day, I ran some quick damp tests to check for any excess moisture that might have prevented me from sealing the floor. We will always do this as excess moisture can affect the sealer curing.

The customer was very happy with the clean and the floor was dry so we discussed sealer options to find out their preference for Matt or Satin finish. With the decision made to go with a Satin finish I began the application of the Tile Doctor Seal and Go which enhances the look of the stone with an aesthetically pleasing low-sheen finish, as well as providing on-going protection against ingrained dirt and staining.

A total of five coats of Seal and Go were needed to seal the Slate tiles and as you can see from the photos the sealer really put the life back into the floor.

Exterior Slate Patio Paving Tile Renovation in Thatcham


Details below of a job I completed earlier in the summer in the Berkshire town of Thatcham which is just east of Newbury. The customer had a lovely Slate Patio installed the year before which had not been sealed by the builder and it had since become dull, light grey and unpleasing to the eye. Additionally there was a haze on tiles from sand and cement that had been used to point between the paving which the customer couldn’t remove.

I first went round there to take a look at the job and work out a price; we often get asked to quote over the phone but it’s really difficult to do that without look at the job as you never know how things are going to work out unless you do a test clean. In this case I was able to demonstrate the process to the customer on one of the paving tiles which you can easily pick out in the photographs below.

Happy with the demonstration I was given the job to do the whole patio so I arranged to a date to come back and do the work.

On my return the first job was to tackle the sand and cement haze that was covering much of the slate patio. Fortunately for me the builder had not sealed the tiles so this was just a straightforward case of applying a solution of Tile Doctor Grout Clean-Up, leaving it to dwell for ten minutes and then scrubbing it into the paving with a mechanical scrubbing machine to release the sandy haze as well as breaking down the soils on the tiles.

You should be aware that Grout Clean-Up is an acid based product and Slate like most natural stone is acid sensitive so it’s important to remove it as soon as its done its job and rinse down the stone with water soon after.

To rinse the slate patio I used our specialist truck mounted systems which gently blasts the soils from the stone with hot pressurised water whilst simultaneously recapturing the waste back into a tank on the van. This action also neutralises the stones which is important before applying sealer. The Slate pavers were then allowed to dry and being a very hot day this only took a couple of hours.

After a long lunch I returned to find the Slate was dry but still looking rather grey so to restore the natural dark colours to the stone I applied a coating of Tile Doctor Stone Oil then after approximately 1 hour any excess stone oil was buffed off the tiles leaving it to fully dry off overnight.

The following day I returned to apply two liberal coats of Tile Doctor Ultra Seal which is a solvent based no-sheen, natural-look penetrating sealer that will provide the needed protection from the elements and make it easier to clean in future.

My customer was very pleased with the final results and left the following feedback on the Tile Doctor feedback system.

“I had my patio and path cleaned and sealed. The service from the whole team has been exemplary from start to finish and I am delighted with the work that has been carried out. My particular thanks to Dennis who was friendly, helpful and exceptionally professional. He explained everything he was going to do and why, kept me informed throughout and worked really hard to produce a fantastic finish on my patio and path. I’m really grateful and will most definitely be recommending to friends. Thank you”

Lower Courtyard Slate Patio Cleaning 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!
