Pictures below of a job we did cleaning and re-sealing a 25m2 Saltillo Terracotta tiled floor installed in the kitchen of a house on a working farm outside Abridge, Essex. The owner had been applying coats of sealer for the last 10 years or so and over the course of time a bad build-up of layers of sealer had occurred causing and un-even and darkening effect on the tile (see picture below).
Cleaning Saltillo Terracotta Tile
Removing the old sealer to get back to the bare Terracotta surface was incredibly hard work, normally we can get most of the sealer off with a strong dilution of Tile Doctor Pro-Clean but in this case something a lot stronger was required so we applied Tile Doctor Remove and Go (which is a coatings remover designed for taking off sealers and other coatings from tile) mixed 50/50 with Nano Tech Ultra-clean which adds tiny abrasive particles to the mix. We applied the resulting solution and let it soak in for 30 minutes before tackling it with scrubbers and a steamer, gradually over the course of three days we managed to remove all of the sealer. We rinsed the Terracotta down with clean water to remove any trace of chemical and neutralise the floor before sealing and then left it to dry out.
Sealing Saltillo Terracotta Tile
We left the floor for 10 days to dry out and came back to seal it using two coats of Tile Doctor Colour Grow which is a colour enhancing sealer that protects the tile as well bringing out the natural colour in the tile.
I left the floor to cure overnight, and came back the next day to finish sealing with Tile Doctor Seal and Go, Seal and Go is a water based sealer so it doesn’t give off an odour when it’s drying and also offers durable stain protection together with a low sheen finish. In the end the floor actually took seven coats of Seal and Go before it was fully sealed, this naturally took a long time to apply as you have to wait for it to dry before applying the next coat. Needless to say this was a very long job but the difference was remarkable and the owner was very happy with the result.
