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.

Grout Re-Coloured in Buckinghamshire

We were asked to improve the appearance of this Ceramic tiled floor and Grout installed in a kitchen in Chalfont St Giles which over a few years had become difficult to keep clean and the grout lines had become stained and discoloured.

Cleaning Tile and Grout

Our first task on day one was to clean the Ceramic tiles and Grout so we created a diluted 50/50 mixture of tile doctor Pro-Clean and Nanotech UltraClean, the two products combine to provide a very powerful tile friendly alkaline cleaner with tiny sized abrasive particles. This was left to soak into the tile and grout before being agitated and scrubbed with a scrubbing machine running on low speed. We also used stiff grout hand brushes along the grout lines. Once we were happy with the overall condition of the tile and grout it was washed down using clean water and the resultant soiled solution extracted from the floor using a wet vacuum. I’m pleased to say that using this method we were able to return the tile and grout back to its original colour.

Whilst this was a fantastic transformation the grout lines being porous would untreated soon become dirty and discoloured. The only answer to this problem is a permanent colour seal to the grout lines which not only aids the future floor cleaning, but improves the whole appearance of the floor.

Applying the Grout Colour

Before applying a Grout Colour it’s important to ensure the grout is clean of grease and dirt naturally we had just cleaned this floor so this was not a problem I only mention it in case you were considering taking on a similar task yourself.

Once the grout has dried you can start applying the colourant which is a relatively straightforward process of squeezing the product onto a toothbrush and running it onto the grout. Don’t be tempted to use an old toothbrush for this purpose as it may contaminate the colourant leading to discolouration in the finish.

We completed the project the next day using an Aqua Mix sand coloured Grout Colourant; the customer was extremely pleased and commented how whole clean and efficient the process was.
