Achieving the Consistent Appearance of old Grout using Grout Colourant

    The task of keeping these white Ceramic Kitchen and Conservatory tiles clean was proving very challenging for this customer, who lives in the town of Somerton in Somerset. Somerton is known for its bustling market, which has supposedly been run on a weekly basis since the Middle Ages, and its famous ‘Market Cross’ at the centre of the beautiful marketplace is a popular tourist attraction for visitors to the West Country.

    It probably comes as no surprise to anyone that white tiles are often more difficult to keep clean than others. However, in this case, rather than being badly marked or damaged, these Ceramic tiles had become dirty due to the surface being pitted rather than smooth which trapped ground in marks from spills and dirty footprints etc. The pitted rough surface is very characteristic and provides better grip however they do trap dirt are therefore more difficult to keep clean.

    The grout had also suffered over the years, losing a lot of its colour in the process so as well as cleaning the tiles we agreed to give the grout a really deep clean and also to colour the grout to make it more uniform.

    Cleaning a Pitted Ceramic Tiled Floor

    To clean the tiles, I firstly created a strong diluted of Tile Doctor Pro Clean and applied it liberally across the entire floor, leaving it to dwell and soak into the tile for a short period in order to soften the ingrained dirt. I then used my heavy weight rotary machine fitted with a black scrubbing pad to agitate the solution and break down the muck.

    Once satisfied with the condition of the tiles I turned my attention to the grout lines, cleaning them carefully by hand using a stiff tile cleaning brush and the same solution of Pro Clean and water. This provided a deep, penetrating that clean that left the grout lines clean and free from the dirt and grease that had dulled their appearance for so long.

    With some great results achieved through the cleaning, I rinsed the whole floor to wash away any leftover Pro-Clean and left it to dry fully overnight.

    Recolouring Grout for a Ceramic Tiled Floor

    I returned to the property the next day to check on the floor and after ensuring the floor was completely dry, proceeded to recolour the grout lines using Tile Doctor’s Grout Colourant. Our Grout Colourants are a waterborne epoxy that recolours, seals and rejuvenates existing grout joints and is available in ten different colours ranging from white to dark greys. The scrubbing with Pro-Clean the day before would also ensure the surface of the grout was clean and would make a good surface for the colourant to bond with.

    Since in the past the grout lines had undergone a number of repairs, the existing colour was a mix of different greys. It made most sense then that they picked our ‘Natural Grey’ Grout Colourant for me to use. I painted the Colourant on carefully and waited for 30 minutes before removing any excess, leaving the grout lines perfectly covered in a uniform colour.

    The difference was really noticeable and the property owner was really happy with the results. As you can see from the photos, the new grey Colourant really made the grout lines stand out against the clean white Ceramic tiles. Another satisfied customer.
