This customer from Greenhithe, Kent contacted Tile Doctor to have the tiles in her bathroom refreshed; the tiles which were looking tired and poor ventilation had caused her grouting to go black. This is not uncommon in the UK due to the inclement weather and tighter building regulations designed to promote draught proofing and insulation leaving moisture trapped in the house.
Bathroom Tile and Grout Cleaning
I first started off by cleaning all the tiles down with a weak solution of Tile Doctor Pro-Clean which is a multi-purpose cleaning product; there wasn’t a large amount of grime on the tiles and just general wear and tear on the floor with Limescale and water marks on the wall tiles. I then set about cleaning up the blackened grout with a steam cleaner followed by Tile Doctor Grout Colourant Pre-Treat cleaner, an acid based cleaner that etches the grout in order for it to accept the grout colourant. After cleaning and etching the grout joints they were rinsed down with plenty of water to remove any trace of chemical and then dried them out to receive the grout colourant.
Removing Grout Haze from Quarry Tiles
The grouting to the wall tiling in the bathroom was white, and the customer wanted it looking the same only fresher, so white grout colourant was applied. The grouting to the kitchen floor was originally a sand colour, but the customer wanted something more contrasting this time, so natural grey was used. Once the grout colourant was applied, it was allowed to set for 30mins before the edges were cleaned up. I finished by renewing the mastic sealant around the edges of the bath.
The job took a day and as you can see from the photographs made a huge difference to the bathroom and kitchen, needless to say the customer was really happy with the end result.
