A few months back I posted a story about cleaning Catalan Terracotta tiles where I mentioned that Terracotta tiles are made all over the world. To prove the point I thought you might be interested to read about this Mexican Terracotta Tiled floor I cleaned recently at a house in York.
The customer actually had two floors they wanted me to clean, the other was a Victorian Tiled floor which is cleaned using a similar process but I’ll post about that separately. Both floors looked a bit tired but especially the Mexican Terracotta which looked dull and lifeless additionally the Grout had gone black when it should have been a Sandstone colour.
Mexican Terracotta tiles are invariably hand made and made to the same standard as other makes such as Spanish, as a result the porosity levels between each tile can vary greatly which makes them harder to maintain.
Cleaning Mexican Terracotta Tiles
I cleaned the floor using a strong 1:3 dilution of Tile Doctor Pro-Clean with water which is an effective alkaline Tile and Grout cleaner that will clean and strip old sealers from tiles when used in a strong dilution such as on this occasion. I left it to soak into the tile for about ten minutes before scrubbing it in with a black scrubbing pad fitted to a rotary floor machine. This process made a different but the machine couldn’t cope with the “Bull Nose” edges to I had so spend a lot of time cleaning the old fashioned way using a scrubbing brush and a lot of elbow grease. I had the same issue with the grout which being slightly recessed wasn’t cleaned sufficiently by the machine; however I have narrow scrubbing brush that works well for this purpose.
The floor was rinsed with water and the soiled cleaning solution was extracted using a wet vacuum. I could then see those area’s that needed more work and spot cleaned them with more Pro-Clean until I was satisfied all the previous sealer was gone and the tile and grout was as clean as it could be.
The tiles were given a final rinse with water and the wet vacuum used again to extract as much moisture off the floor as possible. The next step would be to seal, however the tiles would need to be dry for that to happen and given Terracotta is notoriously porous and absorbs water quickly l decided after I’d leave the floor to dry out for two days.
Sealing Mexican Terracotta Tiles
Upon my return to the property I ran some quick damp tests, which revealed the tiles were ready to be sealed. I then applied four coats of Tile Doctor Seal and Go which provides a satin finish and really improves the look of Terracotta.
My customer was very happy with the transformation that had occurred to their floor and I think you will agree from the photographs the floor looks much healthier.
