This owner of this house built around 1900 in Cardiff had asked me if I could make their look any better following their attempt at renovating their original Victorian Tiled floor. I examined the floor and established that they had sealed the floor without testing for moisture also it seemed it had been sealed but not correctly cleaned and more importantly not rinsed thoroughly to eradicate any cleaning solutions first; the results as you can see has caused a terrible patchy mess .
Cleaning a Victorian Tiled Floor
The floor was tested for moisture first which established it was dry and also established a baseline as to what to look for later. The next step was to remove any sealers present which proved very difficult because the sealer had only been applied 6 months earlier and applied thickly with a roller. I used three litres of Tile Doctor Remove and Go in total to strip 6 m2 applying it, letting it soak in and then scrubbing it in to get the sealer off. It took multiple rounds of scrubbing but once the sealer was removed I then went over the floor with Tile Doctor Grout Clean-Up to remove any grout smears and mineral deposits and then gave the floor a thorough rinse with plenty of clean water. To make sure I had given the floor a thorough clean the floor was then finished off more Remove and Go mixed with Tile Doctor NanoTech Ultra-Clean to make it more effective and then steam cleaned. The floor was then rinsed again with another two rinses with fresh cold clean water which was then removed with a wet vacuum I worked.
Sealing a Victorian Floor Sealing
The floor was left to dry out and I came back on two occasions to check if it was dry enough to seal. The first time I visited was three days later and the floor had a high moisture level, I tested again after five days and the readings were ok to carry on with the sealing stage. The customer wanted a satin finish so I went ahead and sealed the floor with several coats of Tile Doctor Seal and Go with great results as you can see.
