Renovating Riven Chinese Slate Tiles in a Water Damaged Kitchen, Shipdham

Slow leaking underfloor pipes are guaranteed to wreck the look of an expensive tiled floor and this is exactly what had happened at our client’s house in the village of Shipdham. The problem occurred in the Kitchen and due to the slow nature of the leak it was some time before the problem was diagnosed and repaired. This resulted in a huge damp problem affecting the riven Chinese Slate tiled floor, damaging the sealer and resulting in white efflorescence salts being regularly deposited across the whole area.

The old kitchen units had been removed and the floor partially excavated to access and repair the leaking pipework, after which a new section of slate tiles had been re-laid. The new and the old sections were noticeable, and part of my job would be to clean the old tiles to a standard where they would blend in with the new.

The first job was to deep-clean the floor using a strong solution of Tile Doctor Pro-Clean mixed with a small quantity of Tile Doctor Remove and Go, which would help to dissolve the damaged sealer. This poured onto the floor and left to soak in for ten minutes before being scrubbed into the slate with our rotary machine fitted with a brush attachment. This brush scrubs right into the uneven surface of the tiles and makes light work of what can be quite a physical job. This process releases a lot dirt and old sealer from the tile which is effectively removed using another machine that gives the floor a power rinse at the same time.

The grout lines and parts of the riven surface which were still soiled were cleaned by hand using angle head brushes and Tile Doctor Oxy-Gel, which is a concentrated version of Pro-Clean in gel form which makes it a lot easier to contain in a small area. Having satisfied ourselves that the floor was finally clean, we left it to dry thoroughly overnight with assistance from our dehumidifier.

On our return the following day, we damp tested the floor and found that the moisture content was a little higher than we would have liked and this would certainly cause a problem with the standard Tile Doctor acrylic sealer which is water based. In our experience water-based sealers are often only successfully applied if the conditions are ideal and the moisture content of the stone is very low. We chose, therefore, to use a slightly different product in the form of Tile Doctor Seal and Go Extra which is microporous and has a higher acrylic solids content than the standard product, making it ideal in situations where dampness in the tile is an issue but the client wants a sheen finish to make daily maintenance easier.

Six coats of Seal and Go Extra were applied in total, the result had the sheen finish the client wanted and the sealer enhanced the different colours in the slate in the process. The sealer will provide excellent on-going protection and being a fully breathable sealer, it will not be impacted by any damp issues as the floor dries out completely over time.

Reclaimed Slate Floor Renovation near Norwich

When the old Rowntree Mackintosh sweet factory at Chapelfield in Norwich was closed down and eventually demolished, our client acquired a quantity of the beautiful green/black slate flooring tiles which had formed part of the reception area of the plant. They had laid these tiles edge to edge with no grouting in their large kitchen/dining room extension at their home in the village of Wreningham and the result was perhaps one of the most impressive examples of high-quality slate flooring we have ever seen in any location.

The Slate floor tiles had been protected against oil and fluid spillages with the application of a penetrating sealer after installation at the property but, over the ensuing years, there had been some inevitable degradation of the sealer and the entire area was now in need of a thorough deep-clean and reseal in order to remove the coating of general grime, bring out the strikingly deep colour and restore the stain resistance.

As there was no topical finish to remove, we proceeded to deep-clean the surface of the tiles using Tile Doctor Pro Clean at a less powerful mix ratio of 1-part water to 5-parts cleaner. This solution was applied to the tiles and left to soak in for ten minutes before being worked in using a black scrubbing pad fitted to our rotary machine.

The resulting muddy slurry was then power rinsed off the floor with water and then extracted with our Ninja machine which has a very powerful vacuum. The high pH product was so effective, no further cleaning was necessary.

The whole area was then dried thoroughly using two large industrial fans which dramatically reduced the drying time, enabling us to move onto sealing later that afternoon. We don’t normally recommend cleaning and sealing in the same day as the floor has to be dry before sealing however in this case we were able to progress through the cleaning process much quicker than anticipated.

Before sealing the floor was spot tested in different places using a moisture meter. All was well, so a single coat of Tile Doctor Colour Grow was applied to the Slate tiles. Colour Grow is a penetrating sealer that seeps into the pores of the stone protecting it from with and as its name suggests also intensified the natural black/green colours of the slate in the process.

Once the first coat was dried I followed up with three coats of Tile Doctor Seal & Go, which further enriched the colour and provided a pleasing mid-sheen finish to the floor surface.

The whole process really put the life back in the stone floor and the tiles which were once dull now look vibrant and colourful.

Restoring Green Westmorland Slate Tiles in Yorkshire

It’s not too common that you find two very different natural stone tiled floors in the same property. However, this is exactly what I discovered on a recent visit to a farmhouse property in Ripley, near Harrogate in North Yorkshire. The owner wanted to restore both their Westmorland Green Slate tiled entranceway and a Blue Moleanos Limestone tiled floor.

Westmorland Green Slate originates from the Lake District in Cumbria – where it has been quarried for many centuries – and is known to be a high quality and popular choice for flooring due to its subtle and pleasant green shades. By contrast, Moleanos Limestone originates from Portugal and is one of more commonly found types of Limestone used in buildings across the world.

But while the two floors were very different, the customer’s objective was the same for both – to restore the appearance of the tiles and return the shine to the stone. Here’s how I did it.

Cleaning and Sealing Westmorland Green Slate Tiles

The first floor I tackled was the Westmorland Green Slate, situated at the entrance to the property. Naturally, given that the tiles are situated in a high traffic area, they were very dirty and required a deep clean.

To do this, I applied a strong dilution of Tile Doctor Pro-Clean, which is our high alkaline, multi-purpose cleaner, stripper, and degreaser. The product was scrubbed into the tiles using a scrubbing pad fitted to a heavy-weight rotary machine to strip away any old sealer and remove the ingrained dirt. One I was satisfied with the condition of the floor it was rinsed with water and a wet vacuum used to remove the now soiled cleaning solution.

Once the floor had been left to dry completely, I was able to give the floor a fresh seal in the form of four coats of Tile Doctor Seal and Go. This sealer is specially formulated to provide both a stain resistant surface seal and a durable low-sheen finish.

Cleaning and Sealing Blue Moleanos Limestone Tiles

Whilst waiting for the slate floor to dry I moved on to restore the Blue Moleanos Limestone tiles, which covered a floor area of 20 square metres, but were looking very sad, tired, and lifeless.

To clean polished Limestone tiles, we typically use a process known as burnishing, which involves the direct application of four different diamond encrusted burnishing pads to grind away old sealers, dirt and stains, before polishing the stone to restore lustre.

First, I used a Coarse 400 grit burnishing pad to strip the floor of the old sealer and remove all grease marks and stains. I had to go over the floor with the pad twice to get rid of some particularly stubborn grease spots.

Having done that, I moved on to focus on building back up the polished appearance of the Limestone by applying the Medium 800 grit, Fine 1500 grit, and Very Fine 3000 grit burnishing pads, with a light spray of water to act as a lubricant with each. This achieved a high-quality satin finish, which I ensured will be protected for the long-term by sealing the stone with Tile Doctor Colour Grow – an impregnating and colour enhancing sealant.

It took me three full days of work to clean, polish and seal both floors – and the hard work paid off, as the customer was absolutely delighted with their rejuvenated tiles!

Deep Cleaning, Sealing a Slate floor

This was a straight forward refresh of a Slate Tiled floor that had been installed in the kitchen of a house the village of Malmesbury. You can see from the photo below how the Slate had become dull with wear and how the grout had become discoloured; it was clear that the previous sealer was starting to fail and the tile and grout was now in need of a deep clean and seal to bring it back to life.

To get the floor clean and remove and remaining sealer a strong dilution of Tile Doctor Pro-clean was brushed over the floor and left it to soak in for around twenty minutes. A grout brush was then used to scrub out all grout lines and get them clean. A black scrubbing pad was then attached to a rotary machine and the entire kitchen floor was scrubbed. This process generated a fair amount of slurry as the remaining sealer, dirt and grime came out of the pores of the tile. This was then removed using a wet vacuum and the floor rinsed thoroughly with clean water.
At this point it became evident that the tiler who installed the floor previously had left grout smears on the surface in some places (aka grout haze) and this was removed using a solution of Tile Doctor Grout Clean-Up applied with a black pad and thoroughly rinsed again to remove any trace of cleaning product. The floor was then dried as much as possible using a wet vacuum and left overnight.

We returned the next day and tested the floor for damp by using a damp meter to ensure it was dry enough to seal; the test came back OK so we proceeded to seal by applying five coats of Tile Doctor Seal & Go which adds a nice subtle sheen to the tile and will protect it from staining for some years to come.
