These clients from Dorking were selling their house soon but were concerned about the appearance of the tile and grout in their shower room and bath. The tiles were White Ceramic laid in the popular Metro style, whilst the tiles looked fine, they were being let down by the grout which had discoloured and was turning a shade of pink and brown. Also, the white mastic sealant was blackening and mouldy in places. Naturally, my clients were keen to ensure that potential buyers were not put off by the bathroom and wanted to get the maximum price for the house sale.
This was a nice straight forward job, the tiles can be easily cleaned, and the mastic removed and reapplied, but it would make a massive difference to the overall look of the room. I gave them a price and they were happy for me to go ahead.
Deep Cleaning a Ceramic Tile and Grout
Firstly, I sprayed the grout with Tile Doctor Duo Clean. This breaks down the accumulated dirt and grime and is left to dwell for 10-15 minutes. Then I brushed the grout with a strong wire brush and showered away the dirt. Permanent discolouration is common so there were places the grout failed to return to its original white colour. To resolve this, I discussed colouring the grout with my customer as removing and re-grouting is a time consuming and expensive option. Additionally, the colourant provides an easy to clean barrier over the grout that will protect it from discolouration going forward.
While waiting for the grout to dry following the cleaning I set about removing the mastic around the shower and walls with a sharp knife.
After an hour of slow cutting the grout was ready for colouring. With a small, stiff paintbrush I painted a White Tile Doctor Grout Colourant into the grout lines, wiping away any excess from the tiles. The colourant dries very quickly so I could apply a second coat where needed soon after.
Once done my final task was to apply the white silicon mastic to all verticals and the bath surround to ensure the bath was watertight. This takes a while to cure so I advised the clients not to use the shower for 24 hours. I should mention the glaze on Ceramic tiles provides adequate protection from dirt, ensuring they are easy to clean and therefore do not require further sealing.
By the end of the day the bathroom looked like a new installation, their trendy Metro style tiles were rejuvenated, and my clients loved the wall of white.
As my client was selling the property there was little point in discussing aftercare, however for your benefit I would recommend cleaning with Tile Doctor Aqua-Pro. This product will neutralise any acid build up caused by shampoos and shower products in the first place and it is these acids that cause discoloration over time.
Now I don’t want to worry anyone about the word acids, the human skin is slightly acidic so the products we use on our skin are designed for this, but if your eyes sting slightly when they come into contact with the shampoo then that is the acid. Naturally, it washes out with water, but you can imagine what it will do to your grout, tiles, and silicone over a long period of time.
