Terracotta tiles are made all over the world and not surprisingly are very popular around the Mediterranean which is where these Catalan Terracotta Tiles were imported from.
They had been installed in a large former farmhouse outside of Halifax in West Yorkshire about twenty years earlier and had never really been subject to an effective maintenance regime. They were now looking very tired and dirty indeed and well overdue a deep clean and reseal.
Cleaning Spanish Terracotta Tiles
I cleaned the floor using a 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 got most of the dirt off but the pad didn’t have good contact with all the tiles as many were convex in shape as Catalan tiles often are. This became apparent after rinsing the soiled cleaning solution off the floor with more water and extracting the soil with a wet vacuum.
To make sure all the missed areas were cleaned I applied more Pro-Clean and scrubbed them by hand with a scrubbing brush. I also took the opportunity to clean the grout as well which was a long job as the tiles were only 6 inches square so there was a lot of grout to do.
The little white tile inserts between the Terracotta tiles are called Tacos and they came up particularly well during cleaning.
Sealing Spanish Terracotta Tiles
Once the clean had been completed I left the tiles to dry off for two days before returning to seal them. It’s important that the tiles are bone dry before applying a sealer as any moisture can cause unexpected results.
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, our topical sealer which provides a satin finish and really improves the look of Terracotta floor.
My customer was very happy with the finished result and I think you will agree the floor looks so much brighter and healthier.
