Dealing with Darkened Grout

    This was a straight forward Grout Colouring job at a house in the market town of Tamworth, Staffordshire. The tiles had been installed with a white grout and over the years the grout had become darker as the dirt had become ingrained into the porous top layer. This is often the case with Porcelain and Ceramic tiles whose looks always outlive that of the grout.

    Cleaning and Colouring Grout

    The customer was keen to get the grouting looking the same as it was when first installed and so with that aim in mind a dilution of Tile Doctor Pro-Clean was applied and scrubbed into the grout lines and then washed off with water. Pro-Clean is a strong alkaline cleaning product that does a good job cleaning up grout however it can only do so much and in this case although it made a difference there were many areas which were too stained.

    The next step was to apply a grout colouring product, they come in a number of different colours and the best match to the original colour was Ivory. The Pro-Clean had already prepared the surface so no need to use a pre-treater, it was just a question of waiting for the grout to dry and then apply the colourant.

    Applying grout colourant is fiddly work but you do get the pleasure of watching the floor become slowly transformed, also the colourant works as a sealant which will prevent staining and make the grout very easy to clean going forward.
