Mexican Terracotta is a lot more porous than typical Spanish or Italian clays, because of this it’s more prone to trapping dirt and needs to be sealed to protect it. These Mexican Terracotta floor tiles installed in a house in Lewes, East Sussex were no different and were proving difficult to keep clean; apologies in advance for the photographs, on refection they are not my best.
Cleaning Mexican Terracotta Tiles
The dirt was quite engrained and so a dilution of Tile Doctor Pro-Clean mixed one part Pro-Clean to ten parts water was applied to the terracotta tile and grout and left to soak in. The solution was then agitated using a floor buffing machine fitted with a black scrubbing pad. It’s important to make sure you use the right concentration of floor cleaning product, too little and if won’t be effective and too much will mean your having to wash the floor down more as if you leave any on the floor tile it can upset the sealer. It’s recommended therefore to do a small test before cleaning the entire floor. Once we were happy with the condition of the tiles we used stiff hand held brushes on the grout to give that also a scrub before removing the all the solution with a wet vacuum, rinsing the floor down and then left it dry overnight.
Sealing Mexican Terracotta floor tiles
Once cleaned and fully dried we came back and applied nine coats of Tile Doctor Seal and Go which is a durable low sheen sealer that will protect the grout and tile from staining. We advised the customer that due to its softer clay further top up coats may be necessary. We left what was remaining of the Seal and Go for this purpose and advised them that if the seal faded slightly then this was then the best time to apply a further coat.
