Here’s a quick grout cleaning and re-colouring job I completed in the town of Canvey Island, Essex. Canvey Island lies on the south east coast, and lies just above sea level which in my job is always worth noting as the area can be prone to flooding. This wasn’t the problem here though, simply put, my client was unhappy with the colour of their grout, and wanted it re-coloured to a darker shade to match the grey Ceramic floor tiles.

Cleaning the grout before re-colouring is essential because, as many readers are probably well aware, grouts are porous and therefore can very easily absorb dirt and grease. Most often this will result in grout discolouration if not dealt with promptly.

Cleaning and Re-Colouring the grout lines of a Ceramic tiled floor

So, as mentioned above the first step in the re-colouring process involved cleaning the grout lines. For this Tile Doctor has a special Pre-Treat Cleaner which is sprayed on and scrubbed into the grout to both remove any existing dirt and also to prepare the grout joints for a superior bond with the Grout Colourant. Once complete the grout lines looked clean and refreshed.

To clean the ceramic I diluted one part Tile Doctor Pro-Clean to three parts water, and used it to wash down the Ceramic tiles, leaving a consistent level of cleanliness across the entire floor. I then rinsed the floor with water which was then extracted using a wet vacuum and waited for 3 hours for the floor to dry.

Once dry, I began the process of applying the Charcoal Grey (as chosen by the client) Grout Colourant to the grout lines. As well as changing the colour the colourant also forms a barrier over the grout sealing it in and protecting it from future staining for years to come.

Then, once dry, the floor was given another quick clean using a light spray of water and a white buffing pad, resulting in an aesthetically pleasing sheen finish. My client was very happy with the outcome and now has the floor they wanted.
