Newly built properties are not without their problems and often take a while to resolve all the snagging which occasionally extends to resolving problems with newly laid tiled floors. At this new property in the village of Malvern, and overlooked by the Malvern hills, the builders had left the Terracotta tiled kitchen floor covered in grout smears (also known as Grout Haze) following installation. They had also neglected to seal the tiles, which was actually quite fortunate in this case as they would have sealed in the grout haze, making it more difficult to remove.
Naturally, the property owner wanted the problem to be resolved as soon as possible, and for me to make the tiles easy to keep clean in future, which can be achieved by sealing the tile.
Removing Grout Haze from a Terracotta Tiled Floor
Before starting work, I made sure to fully protect any exposed woodwork with a plastic sheet covering to protect them from potential damage. I then proceeded to give the floor a thorough clean, using Tile Doctor Remove and Go to clean the floor and eradicate some stains that had been left behind as a result of the building work.
Next, I paid special attention to the grout, where the very visible problem of grout haze had arisen. To neutralise these smears I used Tile Doctor Grout Clean Up, a concentrated phosphoric acid cleaner that can also remove alkaline mineral deposits and efflorescence. Grout Clean Up is only to be used on acid resistant stone, as sensitive stone can suffer from irreparable etching if it comes into contact with the product.
Once completely clean and free of grout smears the floor was thoroughly rinsed with water to remove any trace of product and then dried as much as possible with a wet vacuum, afterwards an air mover was installed to speed up the drying process.
Sealing a Terracotta Tiled Floor
Later that afternoon the floor was dry and I was able to apply a sealer. To do this I opted to use several coats of Tile Doctor Seal and Go Extra, a topical, fully breathable sealer that works really well on Terracotta.
