Occasionally I get a call to pop down to Sandbanks on the Dorset Coast which is well known for containing the most expensive property in the UK outside of London. This particular residence had a Travertine tiled hallway which was badly in need of renovation, it had become very soiled and dirt had become trapped in holes that has opened up in the stone over time and now needed cleaning and filling.
Cleaning and Filling a Travertine Tiled Floor
I began by applying a dilution of Tile Doctor Pro-Clean which was left to soak into the floor for ten minutes before being worked into the tile and grout using a Numatic buffing machine fitted with a medium brush. I then dried the floor using a hot air gun and filled the holes with Harbro Stone Filler which is an epoxy filler as hard as the stone itself. I carefully scraped off the excess filler before leaving it to set overnight.
Burnishing Travertine Tiles
The next day I used 17″ wet and dry paper to remove the excess filler and to cut out some of the deep scratches in the travertine. This I followed by honing and polishing the floor using Tile Doctor burnishing pads which are diamond encrusted and come in a setup of four pads which are applied one after the other from Coarse, Medium, Fine and then Super Fine to restore the surface polish.
Sealing Travertine Tiles
On the third day I returned to seal the Travertine tiles using Tile Doctor Colour Grow which is a colour enhancing impregnating sealer that soaks into the pores of the stone occupying them and in doing so preventing dirt and soil from becoming ingrained into the stone. Colour Grow is also a colour enhancing product that brings out the colour in the stone
I suspect they have been using a weak acidic supermarket cleaner on the floor and that’s why small holes have been opening up in the Travertine which is a calcareous stone containing lime that can be disolved in acid. Hopefully you advised them to use Tile Doctor Neutral Cleaner instead.
