Renovating a Brazilian Slate Tiled Kitchen Floor in Lancashire

Rough Slate is notorious for homeowners to maintain as dirt can quickly become trapped in the rough surfaces. The example on this page is that of Brazilian Semi Riven Slate installed in the Kitchen of a house in the village of Hornby, which while naturally cleft from the rock loses none of its texture and style and yet has a much smother appearance than the typical rough Slates from China. Less processing means it’s not quite completely smooth but it is a lot less expensive to buy than say a honed or polished Slate which is more difficult to maintain due to various polishing techniques required to keep up the appearance. Brazilian Slate is in fact one of my favourite slates to clean and also one of the most rewarding of Slates to seal as the sealer really does bring out the colour and character of the stone.

Sealers provide a protective barrier on natural stone floors and without it dirt can penetrate into the pores of the stone making it more and more difficult to clean effectively. Unfortunately on this floor the new homeowners were unaware on what sort of Stone it was and had no idea how to look after it which resulted in the sealer wearing down prematurely and the floor becoming dull and un-inviting.

Cleaning Black Semi-Riven Brazilian Slate Tiles

To restore the appearance of the Slate floor we started by taping up the edges of the new kitchen units to protect the wood from splashing. This was followed with an application of a strong dilution of Tile Doctor Pro-clean worked in with a black buffing pad fitted to a buffing machine running at slow speed (working at a slower speed results in less splashing). The pads can struggle to reach the edges and corners so these were cleaned by hand.

Once we had finished on the main floor area we then concentrated on the grout using a steam cleaner and more Pro-clean scrubbed in with a narrow stiff brush.

Last step of the cleaning was to rinse the floor with water to remove any trace of cleaning products from the Slate and then dried off the floor the best we could with our high wattage wet vacuum machine and left the floor to dry off naturally over night.

Sealing Black Semi-Riven Brazilian Slate Tiles

The next day we returned to seal the floor checking first that the floor had completely dried. The customer had requested a matt finish however we have worked on Brazilian Slate many times before and we knew how good they can look with this Satin finish sealer. Naturally its the customers decision so we offered to do a test piece and let them decide if they didn't like it we would strip off the test piece and apply a Matt finish sealer like Tile Doctor Colour Grow instead.

The floor was dry so a couple of coats of Tile Doctor Seal and Go were applied to one Tile so that they could appreciate how it would look. Luckily the customer agreed with us and so we set about sealing the whole floor with Seal and Go.

To speed up the drying process Air Blowers were installed as we worked and it wasn’t long before the sealer was dry and the customers were able to walk on the floor and inspect every area before we left. I’m please to report that they were over the moon with the floor and my recommendation of sealer.


To maintain the slate tiles going forward we always give our customers a free bottle of Tile Doctor pH neutral tile cleaner, which is a little incentive for them to provide some feedback via our website.

Putting the shine back on a Slate floor in Gloucester

This Slate tiled floor in the hallway of a property in Gloucester had been laid 28 years ago, but during this time had received no proper maintenance. The property owner used to clean the tiles once a week using a steam cleaner to little effect.


In fact, we don’t normally recommend steam cleaning sealed surfaces as it will erode the sealer prematurely. After countless years of steam cleaning, I was confident that any traces of old sealer on this floor would be non-existent at this point. This is, of course, a problem because a lack of sealer exposes the stone to ingrained dirt and stains. The effects of this are shown in the photos below: as you can see, the Slate had completely lost its lustre and naturally colourful patina.


I was asked by the property owner to provide this Slate tiled hallway with the restoration that was so long overdue, so I travelled to the house in Gloucester, a city situated near the Welsh border and between the Cotswolds and the Forest of Dean.

Cleaning a Dirty Slate Tiled Hallway

I started the restoration by mixing a strong solution of Tile Doctor Remove and Go combined with Tile Doctor NanoTech HBU. These two products serve different purposes. Remove and Go is a stripper designed to break down any traces of old sealer that might still have existed, as well as any paints and adhesive markings; NanoTech HBU is a potent cleaner which contains nano-sized cleaning particles that penetrate deep into the stone to get underneath tough dirt and stains to dissolve and lift them out. This cleaning solution was spread over the floor and left to dwell for 30 minutes, before being scrubbed in using a black scrubbing pad fitted to a buffing machine. A thick black slurry resulted from this process and this needed to be removed using a wet vacuum.


Next, I repeated this cleaning process using Tile Doctor Pro Clean, our reliable alkaline cleaner, to provide a more thorough clean for the tiles and grout. The slurry was once again removed using a wet vacuum, before I then rinsed the whole floor with fresh water to remove any traces of chemicals. When satisfied with outcome of the cleaning process, I left the floor to dry overnight.

Sealing a Slate Tiled Hallway

Upon arriving back at the property, the next day, I ran some quick moisture tests to check that the floor was dry. Thankfully, there were no damp issues and I was able to seal the tiles using four coats of Tile Doctor Seal and Go, leaving each coat to dry before applying the next. Seal and Go is a water based sealer (so no smell as it dries) which adds durable stain resistance and a low-sheen finish that brings out the best in the slate.


The customer’s reaction to the outcome of the restoration was fantastic. She never expected the floor to turn out so beautifully and was very pleased.

Restoring Old Reclaimed Slate Flagstones in Devon

These lovely old Slate flagstones were reclaimed form an old waterworks in Exeter about twenty years ago and had been laid in an old fisherman cottage in Dawlish during a sympathetic renovation, replacing an old floor that had been laid in the 1970s (which have a lot to answer for with old houses!). The flagstones really looked the part and were larger and thicker than usually available on the market new. Other than being dirty and a pain to clean because of the dogs living in the house, around the edges of some of the larger tiles there was some sort of fluorescent orange residue which was up to 10mm thick in places and as hard as the stone it was adhered to.

Dawlish is a lovely little fishing harbour village on the South-East Cornwall coast with lots of interesting history. For hundreds of years the practice of smuggling imported goods prospered in the area thanks to its convenient harbour. The village is home to only around 5,000 inhabitants.

As you can see from the photo below, the tiles – along with the grout lines - were very dirty and stained. No wonder the property owner was beginning to give up on salvaging them! However, I assured the customer that with the right cleaning products and techniques, I could make a significant improvement to the condition of the floor.

Burnishing and Cleaning Old Slate Flagstones

To tackle the orange residue staining I used a grout removal tool which allowed the natural texture of the stone to remain rather than smoothing off the whole edge. The dirt and staining in the slate flagstones however was so deeply ingrained I felt it best to strip back the affected layer of stone using a process known as burnishing. This involves the application of diamond encrusted burnishing pads to the floor, effectively grinding away the muck to reveal a cleaner surface beneath. When dealing with polished stone such as Limestone, Marble and Travertine, we will normally use a system of four burnishing pads – each with a different level of grit – to gradually restore the shine to the tiles.

However, in the case of these rustic, unpolished Slate Flagstones, I opted only to use only the Coarse and Medium grit burnishing pads to cut back the affected layer of stone, leaving a surface that could subsequently be scrubbed using Tile Doctor Remove and Go. This is a multi-purpose product that strips away any old sealer, adhesive marks and paint stains, while also cleaning the stone and grout.

This process ensured all traces of old sealer were removed and that the whole floor was left fresh and clean. The resulting soiled solution was extracted from the floor using a wet vacuum and the whole area rinsed with fresh water to remove any traces of cleaning product. To end the first day of work, the floor was left to dry overnight.

The village the cottage is situated in is very isolated to traffic; there is a car park at the top of the town and the only option is to walk the nearly half a mile each way to the cottage on the harbour so streamlining the kit used was a necessity! In the end two trips each way go the kit required there and back with the biggest machines being a wet vac and a rotary scrubber.

Sealing Old Slate Flagstones

Returning to the property the next day, I ran some damp tests to check if the floor was dry and ready to be sealed. This is particularly important in older properties like this, as it’s quite likely that there is no damp proof course present and moisture issues are far from uncommon.

Thankfully, the tiles proved dry and I could seal them using Tile Doctor Colour Grow. This impregnating, colour-enhancing sealer provides a robust seal, as well as a natural-look matte finish which really matches the character of these original Flagstones. It also really lifted the natural shades in the stone.


The customer was ecstatic with the result. To make sure the floor can be kept looking great for many years to come, I recommended that the customer clean it regularly using a product called Tile Doctor Stone Soap. It’s specially formulated for the routine maintenance of natural stone floors; not only will it clean the floor very well, it will also continue to add to the natural patina of the stone.

Cleaning and Sealing Slate and Terracotta Tiles Together

I was recently contacted by a client living in the historic market centre of Bicester, one of the fastest growing towns in Oxfordshire. Many will know Bicester for its famous shopping village. They had a small, dirty Terracotta and Slate tiled conservatory which had suffered from water damage and a loss of colour. Terracotta and Slate are examples of naturally porous tiles which can suffer from dirt becoming trapped/ingrained into its pores making it difficult to clean for the regular homeowner with everyday cleaning products. The water damage had also left stubborn stains on the floor which would require professional attention to remove.

Cleaning a Terracotta and Slate tiled floor

My first task was to cover the whole floor with Tile Doctor Remove & Go, mixed with water to form a solution. Remove & Go is a powerful cleaner that needs to be left to dwell for roughly ten minutes when first applied. This allows the product to soak into the pores of the stone, thereby getting underneath dirt and lift it out. After allowing the solution to dwell, I then agitated the surface with a brush attached to a floor machine to remove the particularly difficult muck. In this process of doing this, I unveiled some staining in the floor. To tackle this I used NanoTech HBU (previously known as Ultra Clean), which uses nano-sized particles to remove heavy soil build-up in places other products simply cannot reach. Following this I repeated the cleaning process with Remove & Go until I was satisfied that the conservatory floor had been cleaned to the best of my abilities. All of the resulting soiled residue was quickly extracted using a wet-vac machine. The floor was then given a final rinse before leaving to dry completely overnight before returning the next day to seal the tiles.

Sealing a Terracotta and Slate tiled floor

On day two and after checking the floor had dried, I applied several coatings of Tile Doctor Seal & Go to seal the floor. This helped to restore the desired colourful sheen finish to the floor, whilst also guaranteeing durable surface protection for the future. Seal & Go is suitable for use on internal, unsealed porous surfaces such as Terracotta, Sandstone, Slate, and more.


My client was very pleased with the results. They were especially happy to see the fantastic natural colours and shades in the tiles brought to life again, after forgetting they were there to begin with!
