Black Slate Kitchen Worktop Renovated Dulwich South London

Removing Limescale from a Black Slate Worktop in a Dulwich Kitchen

I was contacted by a customer of mine from Dulwich who having been impressed with the work I did for them previously cleaning and sealing a stone floor wondered if I could obtain a similar result with the Black Slate worktop installed in their kitchen. I was due to visit the property anyway to perform a maintenance clean on the stone floor anyway so was able to look at it after that work was complete.

I don’t mention this very often but I recommend to owners of polished stone floors that they ask me to return on an annual basis to re-polish the floor and top-up the sealer, we call this a maintenance visit and it ensures the tiles look its best for much longer. The process takes a couple of hours as opposed to a full clean and seal which typically takes two days.

After maintaining the floor I turned my attention to the Black Slate worktop and could see not only had it lost its deep shine it was spotted with ring marks and stained with other contaminates from cooking. I detected that a topical sealer had been used on the Slate in the past but it was now patchy and to ensure the best result this needed to be completely removed, the stone polished and a fresh sealer applied.

Renovating a Stained Black Slate Worktop

To strip off the old sealer I applied Tile Doctor Remove and Go and left it to soak into the Slate for around thirty minutes. Then using a small six-inch pad fitted to a hand-held buffer scrubbed the solution into the stone to remove all the old sealer and clean up the stone. The worktop was then rinsed down with water and a cloth.

With the old sealer removed I set about tackling the ring marks and White staining which were probably caused by water, (limescale) or acids from the use of strong cleaning products or food. I find the best way to tackle deep seated staining on stone is by burnishing the stone with a series of diamond encrusted burnishing pads in different grits. I started with a 200-grit pad with water, vacuuming up the solution as I went, and then went through the remaining set of diamond pads (400, 800, 1500 and 3000 grits) to ensure I had fully honed the stone and restored its polished appearance. With worktops I used the smaller six-inch pads fitted to the hand-held buffer mentioned earlier.

Sealing a Black Slate Kitchen Worktop

Once the worktop was dry I was able to apply a fresh sealer to improve the Black colour and protecting it going forward. For the best result I started off by applying an even coat of Tile Doctor Stone Oil, a sealer that soaks into the Slate enhancing colour and improving strength.

I allowed the Stone Oil to dry for about forty minutes and then followed up with Tile Doctor Colour Grow sealer, this also enhances the colour whilst providing durable surface protection. I buffed off the final coat with a dry cotton cloth within 15 minutes of it being applied

Once done the Slate Worktop was completely transformed much to the delight of my customer who was relieved something could be done with it. For aftercare I recommend the use of Tile Doctor Stone Patina Spray which is a mild cleaner that will maintain the patina of the stone.

Slate Bathroom Tile Renovation Bermondsey

Green Slate Bathroom Tile Refurbished in Bermondsey SE16

This customer from Bermondsey SE16, was having a new shower tray fitted after discovering a leak. He wanted to know if his Green Slate tiles could be spruced up rather than having to pay out for new tiles and the tiling. The property was a basement flat in a warehouse conversion and with only one bathroom in the property a full bathroom rip out would have been very inconvenient.

The main issue with the tiling which included the wall and floor was they had a lot of white marks on them. My client thought it was limescale, but he couldn’t remove the staining and hence contacted Tile Doctor. After taking a look at the Slate I informed him that the White marks were in fact what was left of an old topical sealer! It seems over years it had broken down and water had penetrated it turning it white.

Removing White Stains from a Green Slate Tiled Bathroom

To begin I applied Tile Doctor Nanotech HBU Remover to the walls and floors, this is a heavy build up remover (HBU) used to remove stains and waxes. The product is quite thick which helps it stick to walls without running off. Its essential to give it a long dwell time so it can get to work breaking down the old sealer. In this case I left it for 45 minutes before scrubbing it into the tile.

Before rinsing I also applied Tile Doctor Remove & Go on top of the Nanotech as this is multi-purpose coatings stripper which removes old sealers. The Nanotech had softened and started to break up the old sealer, and I was using Remove & Go to get into the old sealer and lift it off completely, which it did.

I used a wet vacuum to pick up the soiled solution and then I a steam cleaner to rinse the tiles. I use steam for two reasons, firstly as I want to seal the tiles on the same day rinsing this way doesn’t soak the tiles. Secondly any remaining old sealer gets lifted out by the steam.

Later that day the Slate tile was dry and ready for sealing. I first applied Tile Doctor Colour Grow, which is a colour enhancing impregnating sealer that penetrates the pores of the Slate and protects from within. The sealer is applied with a cloth and worked into the stone, wiping off the excess and then leaving to dry for 30 minutes.

Once dry I then applied a coat of Tile Doctor Stone Oil, again this enhances the colour, but being an oil also improves the mechanical strength of the stone. This was left to dry, for another 30 minutes plus before applying another coat of Colour Grow. I always finish with a sealer as this helps to lock-in the oil.

My customer was very happy with the results and relieved to avoid the expense and inconvenience of having to retile the bathroom. Thankfully that is no longer the case, and the Slate has become a real feature of the bathroom.

For aftercare of shower tiles, especially stone I recommend regularly spraying on a product called Tile Doctor Aqua-Pro which is a mild cleaner designed for use where the tiling has been sealed. A lot of tile cleaning products you find are simply too strong for use on sealed surfaces and can slowly erode the sealer over time.

Terracotta Conservatory Floor Renovation Herne Hill London SE24

Terracotta Conservatory Floor Deep Cleaned and Sealed in Herne Hill SE24

1 Comment / Grout Cleaning, Lewisham Tile Cleaning, Terracotta Tile Cleaning, Work by Category, Work by Location, Work History / Jason Gates

The following photos are of a Terracotta floor I recently worked on in the conservatory of a property in the South London suburb of Herne Hill SE25. The room was going to receive a makeover and they were not sure whether to replace the floor or not. The terracotta tiles were very dirty and although they had tried cleaning it themselves, they struggled to get a result so decided to call in Tile Doctor.

I went over to survey the floor and could see that any sealer that was once on the tiles had completely worn away and without the protection of sealer dirt had become ingrained into the pores of the tile. Once that happens it can be troublesome to remove deep seated dirt from within Terracotta due the porosity of the clay-based tile.

However, having done quite a few of these floors previously I was confident with the right approach it could be deep cleaned and then a fresh sealer applied to protect it going forward. On the subject of sealers, they told me that they did not want a shiny finish so I quoted the job to clean and seal with an impregnating sealer that would meet their requirements.

I quoted for two days work, one day to clean and one day to seal and with the quote agreed the work was scheduled.

Deep Cleaning a Terracotta Conservatory Floor Tiles

On my return I started the cleaning process by applying a strong dilution of Tile Doctor Remove and Go combined 1 to 1 with Nanotech HBU Remover. Remove & Go is a multipurpose stripper with a long dwell time designed to remove old sealers and ingrained stains and the “Nanotech HBU Remover” is a heavy build-up cleaning product that uses nano sized particles to penetrate below the surface and draw out the ingrained dirt and stains.

Nanotech is a gel like substance and combined with the Remove & Go it makes for a powerful double action tile cleaning product. For maximum results It was left to sit on the floor for 30 minutes without allowing it to dry up or soak in. I then scrubbed the solution into the floor with a black scrubbing pad attached to a rotary floor machine. This action released the dirt from the tile and grout causing the cleaning solution to go black. The resulting slurry was then rinsed away with water extracted using a wet vacuum.

With the floor already looking significantly cleaner I moved onto the next step of giving the tiles and acid rinse using a 1:5 parts dilution of Tile Doctor Grout Clean-up. This product is a phosphoric acid based cleaner, which amongst other things removes efflorescence and lime deposits, being acidic it also neutralises the strong alkaline chemicals used to clean. I apply this solution by hand using stainless steel scouring pads for the tiles and a wire brush for the grout lines. I work in one metre square sections at a time, not allowing the solution to sit on the tiles for more than five minutes before vacuuming up the dirty solution.

One I had cleaned the whole floor with the “Grout Clean-Up” solution I then rinsed it with a steam cleaner. I use a steam cleaner for two reasons, for one it doesn’t soak the floor and the heat means it dries quicker and two any stains still there get drawn out by the steam.

Sealing Terracotta Conservatory Floor Tiles

It’s not good practice to apply a sealer to a damp floor as the dampness can cloud the sealer and result in a patchy appearance. Because of this I always seal on a second day and in this case, I left the floor to dry out fully for two days before returning.

To seal the floor, I used four coats of Tile Doctor Colour Grow which is an impregnating sealer that soaks into the pores of the Terracotta occupying the tiny pores and thereby blocking dirt from becoming ingrained there. Colour Grow as its name suggests improves the natural colours in the tile and in this case it did well to bring out the Orange/Red colours in the Terracotta, it also leaves a matt finish as requested by the client.

For aftercare I recommend Tile Doctor Neutral Cleaner, sealers are vulnerable to harsh chemicals so its important to use a cleaner that won’t impact them. It’s always worth checking the small print when buying a cleaner as the wrong product can degrade the sealer and then your back to square one with the floor becoming dirty with ingrained dirt.

Stained Encaustic Shower Tiles Renovated in Forest Hill SE23

Encaustic Cement Tile Cleaning, Lewisham Tile Cleaning, Work by Category, Work by Location, Work History / Jason Gates

The client had recently moved into this property in Forest Hill SE23 and the previous owner had used a professional cleaning company to give the house a thorough clean prior to moving out. Unfortunately, they had used an aggressive acid based cleaner on the reclaimed encaustic tiles around the shower, causing white staining. I was contacted to see if it was possible to remove the stains and correctly seal the tiles to protect them.

I was pleased to tell them it was indeed possible to restore the tiles and we discussed how I would do this. I gave them my quote which they accepted, and we arranged a mutually convenient time to carry out the work. Encaustic tiles are quite unusual they were traditionally made from clay, but today, most modern versions of the tile are made using cement and are often referred to simply as cement tiles.

Cleaning and Restoring an Encaustic Tiled Shower

The first step was to scrub the tiles with a dilution of Tile Doctor Pro-Clean, an alkaline cleaner that is safe to use on Encaustics. The solution was scrubbed into the tile to ensure any remaining soap scum and surface grime was removed. Once done the tiles were rinsed off with water and I moved onto the next of renovating the appearance of the tiles with a set of handheld burnishing pads.

These pads are made from industrial diamonds that clean and remove scratches renovating the surface and closing the pores of the stone. For general cleaning and honing I would normally start with a 400-grit, but with the staining on these tiles, I started with the 200-grit. Once I had gone over all the tiles with the 200-grit pad with water, I then repeated the process with the 400, 800 and 1500 and 3000 pads in sequence. The tiles were rinsed off after each pad and finally left to dry.

Sealing an Encaustic Tiled Shower

Once the tiles had dried it was time to apply a sealer that would further enhance their appearance and protect them. For this I chose to use Tile Doctor Colour Grow as it’s an impregnating, colour enhancing product. It works by soaking into the pores of the tile where dirt can collect, thus protecting it from within.

The sealer was applied thinly with a cloth to all the tiles and allowed to dry for 30 minutes before the next coat was applied. Due to the porosity of these tiles, I applied four coats until I was satisfied, they were fully sealed. Once the tiles were dry, I buffed them with a dry 3000 burnishing pad to leave them with an appealing satin sheen.

The client was pleased with the result and I explained the best way to clean and maintain the tiles for the future would be to use Tile Doctor Aqua-Pro which is designed for use in bathrooms and gentle enough to use every day. They needed to avoid using strong household cleaners on these tiles otherwise the same issue would occur.

Reclaimed Quarry Tiles Patio Restoration in New Cross, SE London

Grout Cleaning, Lewisham Tile Cleaning, Quarry Tile Cleaning, Work by Category, Work by Location, Work History / Jason Gates

This customer based in New Cross South East London had a significant problem with their patio. Their home is a period Victorian property so when choosing a stone for the patio, they bought reclaimed quarry tiles to marry up with the period of the house, and proceeded with their DIY project. Unfortunately they were not aware that quarry tiles are porous until sealed, and grout left on the tile and not wiped off immediately, will leave a grout haze or in this case stick to the tile altogether.

I inspected the tiles and confirmed this was the worst case of grout haze I had ever seen; un-deterred I proceeded to carry out a test clean (you can see this reflected in the photograph below) and this demonstrated successfully that the tiles could be restored.

Cleaning Patio Quarry Tiles

Satisfied with the results of the test clean I proceeded to clean the rest of the floor. For this I used Tile doctor Grout Clean-Up which contains concentrated acid and is designed to penetrate below the surface to remove grout smears; this was diluted 1 to 1 with water which is a very strong mix. I sprayed the solution onto the tiles, working 1sqm at a time, leaving it to dwell on the tiles for a few minutes before scrubbing the tiles by hand with a rough pan cleaner. I then rinsed the area off with water and used my wet vac to remove the soiled solution. The strong mix had the desired effect on the Quarry tiles but it was necessary to go over the area again after spotting some of the worse stains the first application had missed. Happy with the result, I carried out this process across the rest of the patio, working 1 sqm at a time.

Sealing Kitchen Quarry Tiles

When I was finished the customer was very happy with the result, and now had a patio they could use. The customer was keen to carry on with their DIY project, and wanted to seal the patio themselves, so I advised them to use Tile Doctor Colour Grow, which is a colour intensifier and impregnated sealer; this will both protect and enhance the reclaimed quarry tile into the future.
