Slate Floor with Granite Inlay Renovated in Harrogate

I was recently asked to survey an unusual stone floor at a house in in Harrogate comprising of Slate inlaid with Granite. The client advised that it had not been cleaned properly for 20 years and wanted it renovating! It was now definitely overdue a deep clean and professional attention. Fortunately, having worked on these floors for many years I knew I could make a substantial impact and transform its appearance. Fossilized slate is a beautiful stone when cleaned and sealed correctly.

The owner confessed they had actually been sealing the floor every two years but without a deep clean first, so they were effectively sealing in the dirt each time. I discussed with them the process I would use to clean and re-seal the floor and we agreed a price to carry to out the work.

Cleaning Slate and Granite Tiled Kitchen Floor

To remove the layers of old sealer and dirt used a set of Tile Doctor Diamond Burnishing pads. The pads are attached to a rotary floor machine starting with the coarse 400-grit pad which was lubricated with a dilution of Tile Doctor Remove and Go to help strip the floor of dirt and layers of sealer. After rinsing and extracting the soil I worked through the different grades of pads in sequence finishing with the 1500-grit and this time using just water for lubrication.

A set of diamond handheld burnishing blocks were then used to clean up the edges and corners where the large 17” pads struggle to reach. This ensures all areas are treated and free of dirt and old sealer.

The floor was then rinsed and extracted again to remove the remaining soil. I find a wet vacuum is an invaluable tool for this. The floor was then left to dry out overnight ready for sealing the next day.

I returned the next day to seal the floor, first checking with a damp meter that the floor was dry, and the moisture reading was below the acceptable level. These results were fine, so I had a green light to continue and seal the stone.

The customer wanted a shine on the floor so rather than apply a satin sealer which I felt wouldn’t adhere to the stone properly I decided to polish the floor further with a the last of the four burnishing pads which is a very fine 3000-grit pad. You don’t need to use a lot of water with this last pad just a small amount sprayed onto the floor using a technique we refer to as a ‘Spray Burnish’.

To seal the floor, two coats of Tile Doctor Colour Grow were applied. This is an impregnating matt sealer which intensifies the natural colours of this beautiful stone and provides long lasting durable protection.

Even I was impressed with the finished result but more importantly the client was over the moon. To keep the floor looking its best I recommended they use Tile Doctor Stone Soap which is pH neutral. You should always read the label in detail when choosing a floor cleaning product as many are too strong and not recommended for sealed stone surfaces as they will prematurely erode the sealer.

Bolivian Black Slate Floor Renovation in Blackpool

This kitchen floor in Blackpool was laid 20 years prior and comprised of Bolivian Black Slate inlaid with White Ceramic Tozzettos. The slate was now looking dull and unloved and the owner now wanted the floor deep cleaning and resealing to restore its appearance.

We visited the property in Blackpool to inspect the floor and discuss what would be needed to restore the floor. It was clear that the old seal had worn away with use which left the stone vulnerable to ingrained dirt and hard to keep clean. Additionally, there were a few broken tiles near the glazed patio doors that would need replacing but the rest of the floor was solid and just in need of some love and care.

We discussed the process which would involve tile replacement, tile and grout cleaning and then sealing. I worked out a price to complete the job which was accepted and booked in for later in the month.

Cleaning and Repairing a Bolivian Slate Kitchen Floor

We cleaned the tiles with a strong dilution of Tile Doctor Remove and Go which was sprayed onto the floor and left to soak in for ten minutes before being scrubbed in. To scrub the floor, I used a rotary buffing machine fitted with a with a black scrubbing pad and approximately 15kg of additional weight to give the pad more bite. This removed what was left of the original matt sealer which was still evident in the less used parts of the floor. This process released the ingrained dirt from the stone into the cleaning solution which was then rinsed off the floor and extracted with a wet vacuum.

The grout was then deep cleaned with Tile Doctor Pro-Clean which was scrubbed in with a narrow brush and finished with a wire brush on some of the more stained grout lines. After this the wet vacuum was used again machine to extract the loose dirt and sediment and the floor rinsed down with water a few times to restore the pH balance in the floor. With the cleaning finished the floor now needed to dry off so it would be ready for sealing the next day.

Next step was to turn my attention to the cracked tiles near the patio door. I suspect the patio doors were not an original feature and there had been some settlement over the years in the underlying cement. The cracked tiles were removed, and old adhesive and grout scraped out. Fortunately, the customer still had some spares, so these were laid in place with rapid setting adhesive and then grouted in.

Sealing a Bolivian Tiled Kitchen Floor

On the 2nd day we applied a tester of 2 coats of Tile Doctor Seal and Go in a corner area as the customer wasn’t sure if she should stick with a matt colour enhanced finish or satin. The customer liked the satin finish, so we applied four further coats of the Tile Doctor Seal and Go throughout. Each coat is left to dry before applying the next so this process can take some time.

The floor looked fabulous when finished in fact the customer said it almost looked like new, which wasn’t bad for a floor that was 20 years old!

As usual before leaving we discussed aftercare which for the regular cleaning of the Slate I recommend Tile Doctor Neutral Cleaner. Neutral Cleaner as its name suggest is pH neutral so it won’t damage the sealer which can be a problem for cleaning products you find in supermarkets which are basically too strong. You really do need to check the label when choosing a cleaning product for a natural stone or sealed floor as many products are made from a derivative of a bleach which will erode the sealer prematurely with regular use.
