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 Cambridge

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.


Slate Floor Cleaning and Sealing Burwell

Restorative Cleaning and Sealing of a Slate Flooring in Burwell

A client from the village of Burwell near Cambridge had recently moved into a property with a Slate tiled floor and was unhappy with its condition as it never looked clean. After discussing the problem over the phone, it was clear to me that the sealed has worn off and dirt was now lodged deeply in the pores of the stone making it difficult to clean.

The tiles were installed throughout much of the ground floor so there were several areas including the kitchen and living room that needed attention. Apart from the ingrained dirt the Slate floor was in good shape and just needed a deep clean and fresh sealer applied to renovate it.

I created a quote for a restorative clean and seal which was accepted, and a date agreed for the work to begin which should take two days, one to clean and then one to seal.

Deep Cleaning the Slate Tiled Floor

The first step to restore the stone was to remove what was left of the existing sealer. This is necessary to achieve a consistent finish as the wear on a sealer is always uneven due as the busiest areas wearing down first. To do this I sprayed each area of flooring with a dilution of Tile Doctor Remove and Go which is a coatings remover that is ideal for removing sealers, it’s also a powerful cleaning agent.

The Remove and Go was left to soak into the Slate tile for ten minutes before being worked in with a rotary machine fitted with a black scrubbing pad. The grout lines were also scrubbed at this point, this needs to be done manually with a stiff grout brush as the pads struggle to reach into the recesses of the grout lines. The resultant slurry was then rinsed away and extracted with a wet vacuum.

Last step before finishing for the day was to give the floor an acid wash using Tile Doctor Grout Clean-up. This cleans up the tiles by removing old grout smears that happen during installation and further cleans the stone.

After a final rinse and extraction with the wet vacuum the floor was left overnight to dry off.

Sealing Slate Floor Tiles

The next day I returned to apply a protective sealer checking first that the stone was dry using a moisture meter. We don’t recommend applying a sealer to a damp floor as this can lead to a patchy result.

Once satisfied the Slate was dry, multiple coats of Tile Doctor Seal and Go were applied. This is a water-based sealer (so no smell) that adds good stain protection and adds a nice subtle sheen to the tile which really enhanced the colours in the slate.

The Slate floor was completely transformed by the work and my client was so impressed with the result they asked me to return and work my magic on their Travertine tiled bathroom.

For aftercare cleaning of sealed Slate floors, I recommend the use of Tile Doctor Neutral Tile Cleaner which is a mild but effective tile cleaner. You need to be careful when choosing a cleaning product for sealed floors as many products are simply to strong and will erode the sealer prematurely.

Slate Tiled Floor Cubicle Renovation West Wickham

Multi Coloured Slate floor in desperate need of a deep clean West Wickham

Having previously completed the restoration of a stone floor for this client in the village of West Wickham near Cambridge I was asked to return to look at the Multi-Coloured Slate tiles in the Kitchen of a rental property. The Slate floor had been laid throughout the Kitchen/Diner through to the Hallway and Utility room.

Over the years the sealer had worn down and dirt had become engrained in the pores of the Slate and had discoloured the grout. They were now in need of a deep clean and the tenant was pleased to be having the work done. It is always a delight to have an existing client have you back as there is no better testament of how happy they have been your work.

I visited the property to measure the area and carried out a few patch tests to check the best process and from that I was able to provide an accurate quote for the work. Happy with the quote I got the go ahead and a mutually convenient time to do the work was agreed with the tenant. It was a large area so the work would be a little disruptive.

Deep Cleaning a Multi Coloured Slate Tiled Floor

To start I applied a strong dilution of Tile Doctor Remove and Go, left it to soak in for ten minutes and then scrubbed the floor with a black scrubbing pad fitted to rotary machine. This action brought a lot of the ingrained dirt to the surface where I was able to remove it using our van mounted cleaning system that applies pressurised water to the floor whilst simultaneously extracting the soiled water to a tank in the van via a vacuum. This keeps the mess to a real minimum and improves drying times.

The tiles and especially the grout was very dirty and it was necessary to repeat this process a few times, hand scrubbing where necessary until I was satisfied the Slate and Grout was as clean as possible. It was a large area so I had to work in sections until all the floors were complete and once done it was left to dry off overnight.

Returning the following morning work started by taking several moisture readings from each area with a damp meter to ensure the tiles were dry and ready for sealing. The readings were fine so the first of several coats of Tile Doctor Ultra Seal was applied. This sealer is almost invisible and so doesn’t affect the look of the stone leaving it with a completely natural finish.

The client and tenant were very happy with the end result and have ordered some Tile Doctor Neutral Cleaner for the regular cleaning of the stone. Using our cleaner which is pH neutral will ensure the newly applied sealer is not compromised and will keep the floor in tip top condition particularly in the heavy traffic areas.

Slate Floor Duxford After Cleaning and sealing

Dirty and Stained Slate Tiles Refreshed Near Duxford

This wonderful Slate tiled floor at a property near the old village of Duxford had been installed throughout the ground floor kitchen, utility room, dining room, and downstairs toilet, making it a very large area. As such, the property owner had struggled to keep the tile and grout looking it’s best and had tried many off the shelf supermarket-quality products without much success and you can see from the photographs the slate was now looking tired and the grout was quite stained and so we were called in to work our magic

Slate Floor Duxford Before Cleaning
While Slate is typically known for its durability, 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.

Cleaning Dirty Slate Tile

Before starting the cleaning process, we protected the walls and skirting boards from coming into contact with products by covering them with plastic. I also opted to remove the kickboards from around the edges of the kitchen units, kickboards are usually just clipped into place and are easily put back later.

Slate Floor Duxford Before Cleaning Adding Protection
I then applied Tile Doctor Remove and Go to the floor, which is a multi-purpose stripper/cleaner designed to strip away old sealers and remove grout haze, adhesives and paints. It also draws out ingrained stains. The entire floor was blanketed in a thin plastic sheet to give the chemical time to emulsify the old sealers without drying out.

Next, I used our high-pressure extraction system to remove all the emulsified sealers. The system works by applying hot water under high pressure to the floor deep cleaning the tile, whilst simultaneously extracting the dirty water back to a tank on our van. This process did a great job of getting the floor clean and free of old sealers etc., and after completing the initial clean a thorough walk through of the floor was done to identify any stubborn areas that needed further treatment.

Finally, the floor was left to dry overnight.

Sealing Slate Tiles

Upon arriving back at the property, the next day, I ran some quick damp tests to check that the floor was completely dry and ready to be sealed. Once satisfied, I applied several coats of Tile Doctor Seal and Go, 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, it was a large area and you have to wait for the first coat to dry before applying the next so it took some time to complete as I’m sure you can imagine.

You should be able to see the floor was quite transformed after our visit and needless to say the customer was very happy with the result.

Slates Tiles Hemingford Grey After Sealing

Large Slate tiled floor Cleaned and Sealed in Hemingford Grey

This is a 25m2 Slate tiled floor installed in a grade 2 listed coach house in the village of Hemingford Grey on the banks of the river Ouse. It was originally called the six bells and the original coach house sign is still hanging from its original ironwork in the entrance lobby. The slate floor was laid through the kitchen and hallway in 2000 and since then it had just been mopped and extra coats of polishes/waxes had been applied leading to a build-up.

Cleaning the Slate Tiled Floor

Before starting work I protected the kitchen units and Aga cooker in plastic film to protect against splashing and mopped onto the tiles a dilution of Tile Doctor Remove and Go which is a coatings remover. Remove and Go I should mention is not only an effective cleaning product but as its name suggests is ideal for removing sealers from floors.

To get the floor completely clean you need to strip it back to bare tile and because of the layers of sealer we let the Remove and Go soak into the Slate tile for some time before being worked in using a rotary machine fitted with a black scrubbing pad. Then rather than wash the product away we blanketed the floor in a polythene sheet and left for two hours.

The polythene sheet prevents the floor from drying out and allows the chemical process of breaking down the layers of sealant to take place. After removing the sheet we scrubbed the floor again before removing the residue with our high powered internal pressure washing tool.

The floor was now bare and all the natural colours in the slate became far more evident. The tiles do need to be bone dry before sealing however so we left it to dry out for a day and left a number of special air blowers setup around the floor to assist with the drying.

When we returned the third day the floor was dry so we sealed it using five coats of Tile Doctor Seal and Go which is a water based sealer (so no smell) that add good stain protection as well as adding a nice subtle sheen to the tile which really enhanced the colours in the slate.

The customer was ecstatic with the result, so much so that before we left she gave us a thank you card in an envelope. On returning to our unit we opened the card and out dropped £50, well I was amazed, even though we explain all the processes to our clients and take the upmost care at their homes we really didn`t expect that level of generosity. This is how the card read:

“To Mick,
Thank you to you and Tom for your high quality in Service, Integrity and Value x Excellent craftsmanship. Much appreciated. So pleased with your work.
Kind regards. M. Evans

It was a pleasure to work for such a nice lady and we look forward to returning in the New Year to restore some more stone and terracotta flooring for her.

Harston Slate Tiled Floor After Cleaning

Slate Tiled Kitchen Floor Cleaned and Sealed in Harston

These photographs are from that lovely old period property in the village of Harston near Cambridge, you may recall an earlier post where I worked on the Victorian Tiled hallway. These photographs are from the Slate Tiled Kitchen floor which they asked me to clean and re-seal as well.

Cleaning the Slate Tiled Floor

The process for cleaning and sealing slate is very similar to Victorian and Quarry tiles so this was as they say a bread and butter job for a Tile Doctor. The beauty of working in a kitchen is I was able to remove the kick boards instead of having to protect the skirting boards with tape. Once the preparation was done a dilution of Tile Doctor Pro-Clean was applied and left to soak into the Slate tile for a while before being worked in using a rotary machine fitted with a black scrubbing pad. Pro-Clean by the way is an alkaline cleaner so it’s safe to use on tile and stone unlike some acidic products which will cause damage over time.

As before I re-applied Pro-Clean on any stubborn stains and also gave the grout lines a good scrub with a stiff hand brush to make sure they were clean. Once happy with the general condition of the tile it was time to use the spinner tool which applies hot water under pressure effectively rinsing the floor whilst removing the water at the same time with suction. This does a great job of rinsing the floor and removing any trace of cleaning product before sealing, this is important to ensure a good finish when sealing.

The spinner tool does a good job of removing liquids from floors however the tile was still damp so it was left to dry assisted with air blowers until dry. Now normally I would use Tile Doctor Seal and Go to seal slate tile however the customer wanted a matt finish for this surface so it was sealed using two coats of Tile Doctor Ultra Seal which provides a more natural look it’s also recommended for use in food preparation areas.
