The photographs below are from a Victorian tiled hallway floor at a house in Northampton where I was called in by the owner to inspect the floor for restoration, deep cleaning and re-setting of all loose tiles covering around 3sq metres.

Cleaning Victorian Tiles
The initial process was to vacuum and remove any loose debris before applying Tile Doctor Oxy-Gel to the entire area. Oxy-Gel is a strong alkaline based gel cleaner/stripper which is safe to use on tile and grout and being gel based it’s very easy to control. The gel was left to get to work on the dirt for ten minutes before being scrubbed into the tile with a black stripping pad fixed to a rotary floor machine. The resultant slurry and dirt was then rinsed with water and removed using a wet vacuum. The floor now free of dirt and old sealers was now prepared ready for repairs and re-grouting.
Grouting Victorian Tiles
The next step was to remove small sections of loose tiles and then re-fixing and re-grouting as required. We took care to replace tiles into their original position to ensure they sat together correctly. Once the section was replaced I removed the tiles in the next section and repeated this process until the 3sq metres of loose tiles were all reinstalled.

I allowed the grout to dry for a few hours before polishing off excess grout with a cloth and removing difficult grout smears with a weak solution of Tile Doctor Grout Clean-Up. The floor was then rinsed again using water to remove any trace of products and then dried using the wet vacuum.

Sealing Victorian Tiles
I returned a few days later to ensure the floor was completely dry as dampness can be issue with this type of tile, I then vacuumed the floor and gave it a light clean with Tile Doctor Neutral Cleaner to make sure it was spotless before sealing.
Once the floor had dried I took damp readings and when satisfied the floor was dry again I applied three coats of Tile Doctor Colour Grow Sealant for a light sheen finish and to enhance the natural colour of the floor. Colour grow is a penetrating sealer that protects from within by soaking into the pores of the tile stopping dirt from becoming ingrained there, it also enhances colour.

We recommend using a specialist cleaning product such as Tile Doctor Neutral Tile Cleaner for the regular cleaning of sealed tiles. Never use a steam cleaner on a sealed Shower and if you wish to use another product always read the label in detail first, most supermarket tile cleaners are only suitable for Victorian tiles as many are acidic and this will erode and reduce the life of the sealer over time.
