Damaged Sealer Replaced on Black Slate Wall Tiles in a Penge Bathroom

The photographs below are of a Slate Tiled Bathroom at a property in Penge. The customer had an open plan ensuite bathroom and feature wall in Black Slate, unfortunately however the topical sealer had become damaged and now looked terrible. The owner was clearly unhappy with its appearance and called us in to take a look.

I went over to the property to survey the tiles and work out what had happened. In this case I diagnosed that moisture had penetrated beneath the sealer causing it to become white and cloudy. Clearly the sealer used previously was not the best choice for a bathroom where a high level of moisture in the air is common.

The solution would be to remove the old sealer entirely, clean the tile and grout and then apply a suitable impregnating sealer which wouldn’t have the same issue. I worked out a quote along these lines which was accepted and a date set for my return to carry out the work.

Removing Sealer from Black Slate Wall Tiles

I set about removing the old sealer by applying a strong dilution of Tile Doctor Remove and Go which as its name suggests is a coatings remover. Working in one section at a time the solution was decanted into a spray bottle and sprayed onto the wall tile, this mixes the solution with air making it lighter and helps it stick to vertical surfaces better.

After a few minutes the solution was worked into the stone by hand with a scouring pad, the delay gives the product time to start breaking down the old sealer. After scrubbing a section, it was rinsed with water and checked to see if more work was needed. Due to the thickness of the sealer I had to repeat this process several times aided by a steam cleaner before I was happy all the sealer had been removed.

When I was happy that all the damaged sealer had been removed from the Slate tiles, I continued to remove all the sealer from the remaining area. This is important as I would be applying an impregnating sealer later and any remaining sealer would prevent it from soaking into the tile. Also, the last thing you want is different depths of sealer on the stone as it will result in an inconsistent appearance.

When all the sealer had been removed and the Slate was dry, I was then able to re-apply the new sealer. Its important that the stone was dry before applying the new sealer as any dampness in the stone can effect the way the sealer cures.

I chose two products to seal the Black Slate starting with a single coat of Tile Doctor Colour Grow which was selected for several reasons. First, its fully breathable so can cope with moisture, also as its name suggests it contains a colour enhancing formula which helps to bring out the best in dark stone. This product is also an impregnator which basically means it will soak into the stone, occupying the pores and thereby ensuring that any contaminants remain on the surface where they can be easily wiped away.

Once all the Black Slate was covered, I allowed a quick dwell time before rubbing off the excess sealer. After the first coat of Colour Grow had dried I the applied a second coat of Tile Doctor Stone Oil, this really enhances the colour of the stone. The same application and drying process were used, before I carried out a third and final coast of sealer using Colour Grow again.

The combination of sealers brought out the best in the Black Slate which developed a lovely deep shine. The result was completely transformative and as you can imagine the owner was very happy with the improvement.

For aftercare I recommended they clean the shower tiles with Tile Doctor Aqua Pro, this is a gentle but effective spray on shower tile cleaner that has been created for cleaning sealed stone. The formula won’t harm the sealer ensuring it lasts longer.

Victorian Hallway Floor Restoration Hither Green

Carpet Covered Victorian Tiled Hallway Restored in Hither Green

I was asked to view a Victorian tiled communal hallway floor at a property in Hither Green that serviced two Victorian maisonettes. The original Victorian tiles had been covered in carpet and an underlay for many years and now that had worn through the residents decided to investigate having the original tiles restored.

I went over to the property to inspect the floor and create a plan for its restoration. We pulled the carpet back and discovered that a section of tiles were missing and the gap had been backfilled with a sand cement mix. I didn’t know at this point whether the base was solid or if the tiles around the repair would also need to be lifted and replaced.

The Victorian tiles had also been imprinted with the pattern from the carpet underlay and the carpet had been secured to the floor with gripper and adhesive all of which would need to be removed as part of the restoration.

Undaunted with the task at hand I created a quote for this restoration which included replacing the missing tiles with matching replacements then deep cleaning and sealing the tiles to protect them going forward.

Happy with the quote I was given the go-ahead to start the work and pre-order the replacement tiles.

Repairing a Carpet Covered Victorian Tiled Hallway

When I started the work, I found that the base was generally in good condition and solid so not many additional tiles would need to be replaced. I then set about replacing the main body of the tiling and the border where it was needed, using new reproduction geometric tiles. They were as close a match to the original however being newer they were a slightly different shade.

Once all the tiles had been replaced and repaired, I turned my attention to cleaning the floor to remove the staining and years of dirt. I started this with an application of Tile Doctor Remove & Go which is designed to remove sealers and other contaminants. The tiles did not have a visible sealer on them however it did have years of grease and oil that would need to be broken down.

A strong dilution of Remove and go was applied to the tiles and then allowed to dwell and soak in for around half an hour. It was then worked into the floor with a black scrubbing pad fitted to a rotary machine. The dirty solution was then extracted using a wet vacuum.

Next the floor was treated to an acid rinse with an application of Tile Doctor Acid Gel. The acid gel sits on top of the clay-based tiles and doesn’t soak in giving me a longer working time on the tile surface. This was then worked in with soft diamond burnishing pads of 50, 100 and 200-grit. These pads cut into the surface of the tile leaving it very clean but are not strong enough to scratch or change the tile surface. It does however remove the pattern on the tile left by the underlay. The acid will also counter any efflorescent salt issues that may be dormant in the tile which is a common problem with old floors that don’t have the advantage of a damp proof membrane.

Once the acid had been vacuumed up, I rinsed the tiles thoroughly with a steam cleaner, this lifts all the cleaning chemicals out of the tile and dries quickly.

Sealing a Victorian Tiled Hallway

When the floor was totally dry, I set about sealing the tiles which will protect them going forward and ensure that dirt remains on the surface where it easily cleaned away. I use Tile Doctor Colour Grow to seal original Victorian floor tiles, this is an impregnating sealer, that enhances the natural colour of the tiles and leaves the floor with a natural matt finish. Its also fully breathable so will allow moisture to rise through the tile and not become trapped underneath where it could reach out to the walls and cause rising damp.

I applied three coats of Colour Grow, but after the first coat, I noticed that there was a different shade of Red between the new reproduction tiles and the original tiles. As the original tiles were lighter, I applied a coat of Tile Dr “Stone Oil”, to the original tiles only, to help darken them, before applying the third and final coat of Colour Grow.

The restoration completely transformed the floor and the customers were very happy with the result. For aftercare I recommend they use Tile Doctor Neutral Tile Cleaner, which is safe to use on sealed tiles. Many of the products you find in supermarkets are simply too strong and can remove the sealer so its always best to read the label.

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.
