Slate Tile Renovation | Tile Cleaners

[ad_1]

Brazilian Slate is amongst some of the highest quality available in the world and the grey variant is particularly striking when used for large areas of flooring. I mention this as I recently encountered a fantastic Grey Brazilian Slate tiled floor in what turned out to be one our largest domestic restoration projects to date.

The floor, located at a property in the ancient, yet picturesque parish of Studham in South Bedfordshire, covered over 200m2. Unfortunately, it had been installed several years ago with very minimal sealant to keep it protected. This sealant has since worn away and the tiles had suffered as a result. They have become ingrained with dirt, leaving them dull and difficult to clean. Thankfully, we at Tile Doctor are perfectly equipped to resolve these common and highly problematic situations.

The owner was also concerned that areas of the hallway portion of the floor were missing grout and asked if this could be resolved as part of our restoration work. As I mentioned before it was a very large installation with slate tiles laid in four bedrooms, a large hallway with stairs, corridor to the kitchen and dining area, the kitchen and dining area itself, the utility room and the main sitting room. In short, it was no small area and I could envisage being there some time!

Fortunately, the customer arranged to have all furniture moved into storage, so we could have a clear area to work on and were able to get straight to work on arrival.

Cleaning a Brazilian Slate Tiled Floor

Due to the size of the job, the cleaning process was carried out over the course of four days by two Tile Doctor technicians on site. Our first course of action was to mix a strong solution of our reliable high-alkaline cleaner, Tile Doctor Pro-Clean. The solution was applied and agitated into the tiles and grout using specialised grout brushes and a rotary machine with a 17” black scrubbing pad. This not only cleaned the tiles but also removed any old sealant remaining on the floor.

The resulting slurry was quickly soaked up using a wet vacuum. We then applied a dilution of Tile Doctor Grout Clean-Up to all the grout lines, brushing the product in with grout brushes and using the wet vacuum to remove any excess chemicals. Grout Clean-Up is a concentrated phosphoric acid cleaner which removes grout smears from the surface of the tile to ensure there’s nothing that can detract from its natural appearance.

We rinsed and mopped the floor with plain water to neutralise the floor in preparation for sealing and performed a final go over with the wet vacuum. Each area was dried with fans and the cleaning process began again in the next room. This work was repeated in each area as we moved from room to room.

Once the hallway was cleaned, the next course of action was to grout to the areas where it was missing. We did this by matching the colour to the original grout as best as possible. The new grout was then allowed to dry before any excess was removed and a quick clean was performed to avoid any grout haze.

Sealing a Brazilian Slate Tile Floor

Each area was given at least 24 hours to dry before sealing and then sealed with five coats of Tile Doctor Seal and Go sealant. This sealer works really well on Slate adding robust protection whilst achieving a light sheen finish which gave the customer the look they were hoping to achieve.

The Grey Brazilian Slate floor was given a new lease of life and no longer looked dull, as can be seen in the photographs below. Additionally, the customer was delighted with the results and left us the following positive feedback:

“Excellent service. Very friendly and very professional. I would certainly recommend.”

As I mentioned at the start of this post it was a very large floor and as you can imagine it took some time to complete but was well worth the effort.
