It’s always a good idea to double-check any tile cleaning advice you receive with a professional. Sometimes advice can be inaccurate and cause more problems than good. Such was the case with this customer, who lives in the small town of Appleton near Warrington. He had been advised by his builder to use brick acid to remove carpet glue from a newly discovered Quarry tiled floor. Taking the advice, he had washed the floor several times with a solution of brick acid diluted with water. But while this seemed to successfully remove the carpet glue, it also severely discoloured the grout lines, leaving the entire floor looking grubby and unappealing.
The customer was just about to go on holiday, and asked me to see what could be done to restore the floor’s appearance while he was gone. With the house to myself, I got to work.
Cleaning a Stained Quarry Tiled Floor
My first job was to strip the floor property to remove old sealers present on the tile using a strong dilution of our high alkaline cleaner, Tile Doctor Pro Clean. We use this cleaner on all types of tile and natural stone due to its versatility and consistency.
I spread the solution onto the floor and left to dwell for twenty minutes before scrubbing with a black pad fitted to a floor rotary machine. This process also removed the years of dirt and dust that had penetrated through the recently removed carpet. I also paid attention to the grout lines giving them a good scrub with a stiff grout brush, but the acid staining proved to be impossible to remove completely.
While I’m not sure exactly how long the floor had been covered by carpet, it’s safe to say a deep clean had been long, long overdue. Once I had cleaned the floor to a high standard, I used a wet-vac to remove the now dirty cleaning solution from the floor, before leaving it to dry off completely overnight.
Sealing a Quarry Tiled Floor
Upon my return to the property the next day, I tested to make sure the floor was dry enough to seal, which is important as excess moisture can cloud the sealer and damage its performance.
Once satisfied, I applied one coat of Tile Doctor Colour Grow, which is our impregnating sealer designed to really bring out the natural colours in the tile, followed by two coats of Tile Doctor Seal and Go to give the tiles a stain resistant, low-sheen finish.
After this was dry I coloured the grout lines with a matching Tile Doctor Grout Colourant to cover and hide the damage the acid had caused to the grout lines. Finally, I gave the floor three more coats of Seal and Go to add the finishing touches.
My customer returned from holiday to find a completely transformed floor. Looking at the before and after photos, it is easy to see why he was more than happy with the result! Another satisfied customer.
