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.

Stripping Sealer from Slate Tile

This beautiful slate tiled floor installed in the kitchen and hallway of a house in Balham London; I was asked by the owner if we could restore the floor following some work that had been carried out by a builder who had failed in his attempts to remove the old seal. To instill confidence that we could complete the work we carried out a demonstration on a small test area which was enough to prove that money would not be wasted and we were booked for the job, we even agreed to clean the floor on Sunday and seal it on the Monday so it would be ready in time for visitors who were due on the Wednesday.

We cleaned the floor using Tile Doctor Pro-clean which is an alkaline cleaner safe to use on natural stone such as Slate; it’s very good at removing general dirt, grime and even grease. Next step was to remove the remaining sealer using Tile doctor Remove & Go which was applied to a small area at a time. I scrubbed the product into the slate and left it on the surface for a further hour making sure not to let the area dry out which temporarily made it look really dark (see photo below). Finally I gave the floor a through rinse to make sure that no chemical remained on the stone before sealing and then left for the evening.

The next day I checked the floor was dry using a moister meter which thankfully it was and then started to seal using two coats of Tile Doctor Colour Grow which is a colour enhancing sealer design to provide maximum stain protection on natural stone floors whilst bringing out the deep colour in the stone and providing a natural matt finish.

Cleaning Slate Tiles in Staffordshire

This slate tiled floor was installed in the Kitchen of a house in the town of Bridgenorth which is in the Severn Valley Staffordshire. The owner of the house wanted to have the floor deep cleaned and re-sealed and so gave us a call.

Cleaning black slate floor tiles

We set about cleaning the kitchen floor with a mixture of Tile Doctor Pro-Clean mixed 50/50 with Tile Doctor Nano-tech Ultraclean which was worked into the pores of the slate tile using a slow speed rotary machine fitted with a Polyscrub scrubbing pad which can reach down into grouting as well as scrubbing the floor. I then used a wet vacuum to remove the resultant soiled solution before rinsing the floor down twice with cold water, this also neutralises the floor prior to sealing.

I left the floor overnight to dry then came back next day and used a damp test meter to verify the floor was dry and ready for sealing. Once happy I proceed to apply three coats of Tile Doctor Seal & Go which as you can see from the photograph below has really brought out the natural colours in the slate. I used a water test after the third coat was dry to see if the water would form bubble on the surface thus indicating it was dry, which it did thereby indicating the floor was fully sealed.

Overall the job took two days and I’m happy report the customer was delighted with the outcome.
