Complete Restoration of Chinese Slate Tiles in Norton near Daventy

This first photo shows a classic example of a poorly maintained floor, which had faded and lost its colour due to it not being maintained or sealed for many years. In this case, the tiles were Chinese Slate, and were proving very difficult for the property owner to keep clean due to the lack of sealer to protect against dirt and stains. The grout in particular was quite discoloured and of increasing concern to the owner, prompting up the decision to contact me about a restoration job.

I agreed to the work – consisting of a deep clean and the application of a new sealer – and travelled down to the property in Norton near Daventry in Northamptonshire to see what results could be achieved.

Cleaning a Dirty Chinese Slate Tiled Floor

My primary concern when approaching this challenging restoration was to clean the grout which as aforementioned, had become dirty and discoloured. Most tiled floor owners will understand the pain of keeping grout lines clean; regular professional attention is often the easiest solution.

In this scenario, the grout was cleaned using a strong dilution of the alkaline cleaner, Tile Doctor Pro Clean, mixed with warm water. This was applied directly onto the grout lines using a spray bottle and scrubbed in using a hand held grout brush, as shown in the second photo.

With the grout taken care of it was now time to turn attention to the Slate tiles themselves which I tackled with more Pro-Clean but worked in this time using a black scrubbing pad fitted to a rotary machine. This process also stripped away any traces of old, ineffectual sealers from the tiles. This process was followed by machine rinsing the floor with cold water to neutralise the chemicals in preparation for sealing.

Additionally, any particularly stubborn areas of old sealant were removed by hand brushes in combination with undiluted Tile Doctor Remove & Go remover. These areas were also rinsed to fully remove excess cleaning products.

I allowed the floor to dry completely overnight with a dehumidifier installed to assist the drying process. Upon my return to the property the next day I carefully checked the floor was completely dry, since even the slightest amount of excess moisture can cloud the fresh sealer and damage its performance.

Once satisfied that the floor was completely dry I applied five coats of Tile Doctor Seal & Go sealer to achieve a high shine finish, as per the customer’s request. This is the most popular finish for this type of flooring, as it its aesthetically pleasing whole with the assurance that the sealer is providing robust surface protection against stains and dirt.

It’s not until the floor has been washed down that you can spot any stubborn or missed areas so it’s not usual to have to repeat this process until a satisfactory result is obtained. We had both the kitchen and lounge to do and this took most of the day, before leaving for the evening we switched on an air blower to help the floor to dry.

We came back the next day and checked the floor was dry, fortunately the air blower had done its job and we were able to get on with the sealing the floor.

To seal the floor five coats of Tile Doctor Seal and Go were applied using a paint pad applicator. Seal and Go is recommended for Slate tiles and provides good stain protection with a low sheen finish that really does bring the floor alive.
