Recently, I was called to a work on a Porcelain tiled floor in the kitchen of a house in the East Sussex market town of Lewes where the grout was looking tired. Lewes has a long history that dates all the way back to the Saxons and has many old buildings as a result; this house of course with its modern kitchen and Porcelain tiles wasn’t one of them however the grout certainly looked old.
Cleaning Porcelain Tile and Grout floor
The floor was in good physical condition and Porcelain tiles being very robust as they are didn’t need much maintenance however the grout was very stained, and the house owner wanted it freshening up.
My first course of action was to give the whole floor a good clean with a medium dilution of Tile Doctor Pro-Clean scrubbed in with a black pad attached to a floor buffer machine. I paid particular attention to the grout and gave it a good scrub using a narrow brush that was run along the grout lines. The now dirty cleaning solution was rinsed off the floor with water and extracted with a wet vacuum, so I could see the improvement. I could then see the difference the cleaning process had made to the look of the Tile and Grout, but it was clear that some of the staining had gone deep into the grout and no amount of scrubbing would get it looking new again.
Recolouring the Grout
It was clear to me that the only course of action to get back a uniform appearance to the grout would be to recolour it so as an initial step I set about drying the grout.
Once dry I began to recolour the grout using a white Tile Doctor Grout Colourant which was applied using a small brush. I was careful to apply thin, even coats and any excess was removed.
The tiles were of the large format type, so it only took a few hours to colour the grout lines so the whole job took less than a day to complete.
