Terracotta is an interesting type of stone manufactured using a variety of techniques dependant on the country of origin which leads to a number of differences such as Spanish Terracotta being less porous than its Mexican counterpart: the former is semi-hand made and finished in a factory kiln, while the latter is completely handmade. Spanish Terracotta is therefore a lot less than porous and ultimately, of a higher quality.
Cleaning Spanish Terracotta Tiles
I cleaned both sets of Terracotta tiles using the same process, which involved the application of our reliable alkaline cleaner known as Tile a Doctor Pro Clean, diluted with five parts of warm water. Once the solution had been left to dwell for a short period, it was scrubbed into the tiles to remove all dust, dirt, and general muck. This created a slurry of cleaning residue, which I promptly soaked up using a wet vac. A wet vac machine is an essential tool when it comes to cleaning porous tiles since, unlike a traditional mop and bucket, it sucks the excess trapped dirt out of the clay and thus provides a superior clean.
Following this, I applied a small amount of our heavy duty remover, known as Tile Doctor Remove & Go, to deal with some of the more stubborn stains and paint splashes, before rinsing with clean water and wet vaxing in a similar fashion to before.
Sealing Spanish Terracotta Tiles
Once the clean had been completed I left the tiles to dry completely. This can take 12 to 24 hours depending on numerous factors including whether a Damp proof Membrane and underfloor heating has been installed which can really help reduce drying times. Letting the tiles dry completely before sealing is paramount as moisture can cloud the sealer and affect its performance.
Upon my return to the property I ran some quick damp tests, which revealed the tiles were ready to be sealed. I then applied several coats of Tile Doctor Seal and Go, our topical sealer which provides a satin finish and accentuates colour. A new coat of this product is recommended every six months on Terracotta to ensure the continuous protection of the tiles’ soft clay particles.
