Having an effective sealer in place is essential for ensuring the long term condition of tiled floors in fact a lack of sealer can make cleaning the tiles exceptionally difficult as the sealer prevents dirt becoming ingrained in the tile.
Cleaning a Dirty Terracotta Tiled Floor
When I arrived at the property and saw the tiles first hand it became clear that a professional clean had been in need for a long time: greasy looking stains were particularly prevalent and covered large areas of the kitchen floor.
To remove I mixed a strong solution of Tile Doctor Pro Clean, which is a multi-purpose, high-alkaline cleaner, stripper and degreaser, and, working in small areas, applied it to the floor. Working in small sections was important because the stone is very porous and quickly soaked in any product laid down. I scrubbed the cleaner into the stone using a rotary machine fitted with a black scrubbing pad, with the dirt and stains coming away nicely. Pro Clean is highly versatile and can be used for similar cleaning purposes on most types of natural stone floor.
After cleaning each section, I quickly removed the excess dirty water and chemicals with my wet vax machine. Once the whole floor had been cleaned I rinsed it several times with fresh water just to make sure all cleaning chemicals were gone. I then left the floor to dry completely for 36 hours.
Sealing a Terracotta Tiled Floor
When I returned to the property, I conducted several damp tests to check for any areas of the floor that needed further drying. As is almost always the case, there were a few areas that remained slightly damp, and I set about speeding the drying process along using my heat gun. In fact, it actually took me more than three hours to get the floor completely dry, but this was worth the effort as even the slightest excess moisture can damage the performance of the sealer.
Once the floor was finally dried I began sealing the floor with one coat of Tile a Doctor Colour Grow sealer. Colour Grow is an impregnating sealer that penetrates deep into the pores of the stone, thus acting as a shield against ingrained dirt, and also raises the colour of the tiles to provide an aesthetically appealing appearance. sealer. After sealing with Colour Grow, I left the floor to dry for couple of hours and then applied six coats of Tile Doctor Seal & Go, which is a topical sealer that builds up durable protection on the surface of the tiles.
