We were contacted by a national builder of luxury homes to see if we could help sort out a grout problem with an expensive Porcelain tiled floor. Whilst most the work we do relates to the cleaning and sealing of tile and stone we also get asked to consult on related issues. On this occasion it turns out their tiler had done a great job tiling the floor with 240m2 of large format porcelain tiles, but the grout used was the wrong colour.
The property affected was in Nether Alderley which is a very desirable part of East Cheshire about a mile south of Alderley Edge. An appointment was arranged with the property developer to inspect the problem and advise on a solution.

On the day of the visit I was advised that they didn’t want to remove and relay the floor as the cost would be prohibitive and the inconvenience to the homeowner excessive. The developer suggested removing the grout and replacing with the right colour however I advised to do so would take a long time also there was a high risk of chipping the tiles.
The remedy I suggested was to recolour the grout lines with a Tile Doctor Grout Colourant. I have used this method successfully before and I could guarantee there would be no dust and minimal inconvenience to the family, it was an obvious solution. The original grout was grey which really stood out against the cream tile however being quite dark it was clear at least two coats of Ivory grout colourant would be needed.
The builder was happy to go ahead with this solution and we arranged a time to come back. The floor was a very large area so the work would take some time to complete.
Recolouring the Grout on a Porcelain Tiled Floor
Working in sections the first job was to wash and scrub the grout lines with Tile Doctor Grout Colourant Pre- Treatment Cleaner which lightly etches and cleans the grout lines to ensure an improved bond with the new colourant.

The grout was then dried off with some gentle assistance with a heat gun to speed up the process. Once dry the next task was to apply the first coat of Ivory colourant. The colourant is applied by dipping a small brush into the colourant then scrubbing it into the grout lines. Any residue left on the tiles is easily wiped off with a baby wipe to leave a nice crisp line. If you’re doing this yourself then it’s worth noting that Tile Doctor sell a Grout Colourant Kit that includes the pre-treater, colourant and the brush.

It took two days to complete the work saving the house builder thousands of pounds, there was no mess and the family were only slightly inconvenienced. The builder was that impressed we did six more homes on that estate and I understand he has since used the same process with another Tile Doctor in Yorkshire.
Another advantage of the grout colourant is that it forms an impervious layer over the grout, effectively sealing it in and making it much easier to keep clean going forward.
