Resolving Problems With Stained Grout

I was recently called down to Alderton, a small village in the southern part of Northamptonshire most famous for housing the remains of a Norman Castle, known as ‘The Mount’. Unfortunately, this job involved remedying a bit of DIY grout cleaning that had not gone as expected.

As the first photo shows, my client had attempted to use a well-known household cleaning product to remove stains from the grout of his bathroom tiled floor which had not been sealed. Grouts are porous and, as a result, they can easily absorb grease and dirt, so it is understandable that my client would have wanted to try and clean them.

However, it is because of the porous properties of grout that the cleaning product did not remove the stains and, unfortunately, the stains were permanent. What’s more, the cleaning product itself had inflicted acid etching to the parts of the tiles where my client had scrubbed the grout.

So what could be done to remedy the situation? My first action was to clean the grout using professional methods and products in an attempt to reverse the damage.

I did this using Tile Doctor 6″ twister pads, along with a hand-held buffing machine. The cleaning product I chose to use was Tile Doctor Grout Clean Up, which is designed to penetrate beneath the surface of the grout to lift out stains, smears and grout haze.

The final photo above shows the results of my attempts to clean the grout. Due to the extent of the damage, even a powerful cleaner like Grout Clean Up could not completely eliminate the stains completely. This meant that the only option left was to recolour the grout lines.

Recolouring the grout lines

I recoloured the grout lines using a white Tile Doctor Grout Colourant. This product is a waterborne epoxy that not only recolours, but also seals the grout lines in order to protect against further stains in the future.

I coloured all of the grout lines in the bathroom to ensure that everything matched, as well as to create an overall high-quality resilient finish. My client was very happy with results – she also remarked that she would not be letting her husband near the bathroom floor again.
