This is an interesting Terracotta brick tiled floor installed in a house in the village of Alderly Edge. The Terracotta tiles were made in a brick shape which was a popular design found in rural buildings in the 19th century. Although the floor was in good condition the sealer was starting to wear off and being clay Terracotta are porous and trap dirt if not sealed. You can see this in the before photograph below where you can see how the grout and Terracotta has darkened with ingrained dirt.
Cleaning Terracotta Brick Tiles
To get the Terracotta tiles clean and free of any remaining sealer I soaked tiles in a strong dilution of Tile Doctor Pro-Clean and left it to dwell for twenty minutes, Pro-Clean is an alkaline product and so safe to use on tiled floors. Then using a large 17inch black scrubbing pad fitted to a rotary machine and a stiff grout brush proceeded to work the cleaning solution into the tile and grout. The now dirty cleaning solution was removed using a wet vacuum and the floor rinsed down with hot water. Some stubborn areas were spot treated using the same process and once happy with the overall condition of the floor the tiles were thoroughly rinsed three times using hot water to remove any trace of cleaning product prior to sealing and then left to dry overnight.
Sealing Terracotta Brick Tiles
I returned the next day to seal the floor testing it first with a damp meter to make sure it had dried. I then started to seal the tiles and with Terracotta being a very porous material it took eight coats of sealer to do the job. I used Tile Doctor Seal and Go which is a topical sealer that gives Terracotta a subtle gloss finish, it’s also water based so it doesn’t leave a smell as it dries.
This Ceramic tiled bathroom with shower was installed at house Wilmslow and was overdue a refresh. You can see from the photographs below that the bathroom was looking tired and the tile and grout was discoloured with mould and acid build-up from washing products.
Cleaning Ceramic Tile and Grout
The Ceramic tiles and grout were treated using a strong 2:1 dilution of Tile Doctor Pro-Clean which is a strong alkaline Tile and Grout cleaning product. The solution was decanted into a bottle with a trigger spray attachment which when sprayed onto the wall allows the cleaner to mix with air making it lighter and allowing it to stick better. The solution was then worked in using a stiff scrubbing brush by hand before being rinsed off with water; this process was repeated a number of times until we had managed to clean all the areas and then left to dry.
The grout looked better but I was unable to shift some of the staining so we decided to apply a white Grout Colourant, it’s a time consuming process but I think you will agree it made a big difference. Additionally the grout colourant product we use also forms a barrier over the surface making the grout much easier to clean going forward.
The last step was to remove the silicone sealant from along the top of bath and replace with new.
This Terracotta tiled floor installed in a house in Wilmslow had become black and discoloured in areas due to the customer being badly advised on what sealer to use themselves; this resulted in the sealer staying tacky and turning black over time
Cleaning Discoloured Terracotta Tiles
To remove any remaining sealer and deep clean the Terracotta tile we used a strong dilution of Tile Doctor Pro-Clean worked into the floor with a buffing machine fitted with a black scrubbing pad. Pro-Clean is an ideal cleaner for natural floors due to its alkaline formula which doesn’t eat away at the tile like an acidic cleaner, it’s also very good for cleaning up grout however I find that’s best tackled manually using a stiff brush.
Last step in the process was to remove the soiled cleaning solution with a wet vacuum and then wash the whole floor down with clean water in order to neutralise it before sealing, we then left the floor so it could dry overnight.
Sealing and Colouring Terracotta Tiles
The next step was to seal the Terracotta floor and for this we applied Tile Doctor Seal and Go which is a water based sealer recommended for Terracotta floors, it provides stain protection and a low sheen that lifts the look of the floor. Seven coats were required due to the porosity of the Terracotta tile.
