Removing Stained Bathroom Floor Grout with a White Tile Doctor Grout Colourant in Tooting South London

A client was renovating a house in Tooting and wanted to see what could be done to improve the Ceramic floor tiles in the bathroom without the expense of a major overhaul. Having discussed the floor over the phone I was confident it could be improved and agreed a date to come over and survey the tiles and provided a quote for their renovation.

Except for one cracked tile, the tiles were in good condition and I could see it was really the grout that was bringing the bathroom down. The grout was generally discoloured and some had cracked and become loose. This cracking issue is indicative of using an inflexible grout when tiling on a wooden floor as these floors tend to have a bit of movement in them.

I discussed my renovation plan with the customer and provided a quote for carrying out the work which was accepted.

Renovating Bathroom Floor Grout

On the first day I set about raking out the cracked grout and stripping out the silicone between the tile and the bath. Silicone seems to attract mould and although it can be cleaned to some extent, I usually find its more effective to simply replace it. I then tidied up the bathroom to remove the waste grout and silicone, so the area was ready for grouting. I used a flexible White grout for this in order to match the original, although most of that was no longer White due to the staining.

I left the grout to set overnight and returned the next day to complete the job starting with the re-application of the silicone sealant, again in White but this time using an anti-mould variety. My attention then turned to the floor tile grouting which of course was now a mixture of fresh new grout and stained grout. I had realised this would be the result, so I had come prepared and was ready to apply Tile Doctor Grout Colourant in white to make everything uniform.

Before applying the colourant, I prepped the grout joint with Tile Doctor Pre-treat cleaner that is an acidic cleaning solution that is sprayed onto the grout and then scrubbed in. This cleans the grout joints, and the acidic nature of the cleaner helps prepare the grout to achieve a better bond with the colourant. The grout was then wiped with a wet sponge to remove the dirt and then dried ready for the colourant. Although the cleaner had helped to clean the grout and remove surface dirt it can’t do anything about deep seated staining, so colouring was still necessary.

Once the grout was dry the White grout colourant was painted onto the grout using a small brush wiping off any excess from the tile as I went. The Tile Doctor range of Grout Colourants come in eleven different colours and form an epoxy barrier over the grout preventing dirt from reaching the grout line and making it much easier to keep clean.

Once the colourant had dried, I gave the floor a quick clean with Tile Doctor Neutral Tile Cleaner to get the ceramic tiles clean and the job was complete. The refreshed grout now has a consistent white appearance, and it really lifted the appearance of the bathroom.
