This Porcelain tiled floor with a faux stone pattern had previously been sealed with a type of Varnish to give them a shiny appearance however the coating hadn’t taken and had come away allowing dirt to get trapped onto surface giving a dirty appearance. It’s a fact that almost all Ceramic and most Porcelain tiles won’t accept a sealer and if they do it has to be one that works with Micro-Porous tiles.
Cleaning Porcelain Floor Tile and Grout
A strong coating remove product was required to shift the remaining varnish from the tiles so we applied a solution of Tile Doctor Remove and Go combined 50/50 with Nano-Tech Ultra Clean which contains tiny abrasive particles. This solution was left to dwell on the tile for some time before working it into the floor using a rotary machine fitted with a black scrubbing pad. We took the opportunity to scrub the grout at this point as well using a stiff hand brush before removing the cleaning solution using a wet vacuum which I highly recommend for removing liquids from floors. The floor was rinsed with clean water and checked for any further issues; unfortunately the Grout did not respond as well as we had hoped from the cleaning and still had evidence of staining so after checking with the owner we proceeded to apply a grout colourant.
The stripping of the Varnish, cleaning and Grout colouring made a big difference on the floor appearance and now looks revitalised after we had finished and the customer was happy not seal them again.
