We were asked to take a look at these Marble effect Porcelain floor tiles installed in the Kitchen of a house in Maidenhead. Porcelain are a very robust tile which unlike natural stone does not normally need a sealer; they can still become surface stained however especially in a kitchen but the grout is more likely to become stained than the tile which was certainly the case with this floor.
Cleaning black Porcelain floor tiles
To get the Tile and Grout clean we applied a mild dilution of Tile Doctor Pro-Clean which was left to dwell and soak into the tile and grout for twenty to thirty minutes to help break down the oils, grease, skin fats, food fats and other soils which are found in the kitchen and stain the floor. The solution was then worked into the tile using a heavy rotary machine fitted with a white pad and also manually into the grout using a stiff grout scrubbing brush.
Grout Colouring
The Porcelain tiles were now looking fantastic and the grout improved however the trouble with grout is that it is porous, and so gets dirty quickly and is difficult to clean. So to get the Grout back to the colour it once was we applied a Grout Colourant to the grout lines which not only restored the uniform appearance of the grout but also adds an impervious layer to the grout protecting it from staining and making it easy to clean going forward.
Porcelain tiles are really hard wearing and tough but the top layer of grout is porous and will discolour over time especially in a kitchen. If you have this problem then you can protect the grout from staining using a grout sealer.
