I recently paid a visit to a rental property in Chalfont St Peter which had Porcelain tiled floor which needed an End of Tenancy Clean. Porcelain tiling is a great choice for a rental property as its very to maintain however in this case it was the grout that was letting the floor down.
It seems the previous tenant had tried using a white grout pen to colour the grout lines when they first moved in and since then the colourant has started flaking off resulting in a very patchy appearance and the exposed grout becoming darker.
The client wanted me to come in and clean the floor and to make the grout lines unison. The property wasn’t going to be rented out again as the owner was planning to move back in after living abroad for several years.
Deep Cleaning Porcelain Tile and Grout
On the first day I started giving the Porcelain tile and grout a much needed deep clean using a Rocky floor machine fitted with a Silicon Carbide brush and lubricated with a strong dilution of Tile Doctor Pro-Clean. Carbide brushes are perfect for hard floor cleaning and in this case had the additional advantage of cleaning away the flaky grout pen.
This cleaning process was applied section by section vacuuming up the slurry with a wet vacuum along the way. I then hand scrubbed the grout lines with Grout Colourant Pre-Treat Cleaner which is an effective ready-to-use cleaner designed to lightly etch the surface of the grout to ensure a better adhesion with the colourant. It also removes dirt, soil, soap scum and hard water deposits from grout joints. Once everywhere had been treated I mopped the floor with Neutral Tile Cleaner, rinsed with water, extracted with the wet vacuum again before finally leaving the floor to dry off overnight.
Applying White Grout Colourant to a Porcelain Tiled Floor
On day two I knew my main problem would be making sure that the White grout colourant was able to adhere to those areas of grout that had been coloured with the pen. I didn’t have to worry though as it worked perfectly. The application basically involves using a small brush to push the colourant into the grout lines and gently cleaning up the edge of the tiles to remove the excess colourant before it can dry.
After the first coat dried it brighten the floor massively however in some of areas you could still make out the old from the new so I needed to give the grout lines a second coat using the same technique as before. Once the second coat had been applied, I allowed it to settle and go off before giving the floor a check over to make sure I was happy with the result.
My customer was over the moon with the difference and was much relieved that the floor had been restored after the condition the previous tenants had left it in.
