If you want a polished stone floor to keep its appearance, then it will need a regular maintenance plan in place, without it the stone will lose its polish and start to look dull and un-inviting which was the story with this Travertine tiled floor installed throughout much of the grout floor of this house in the village of Great Wilbraham near Cambridge. I was able to find out from the owner that the floor was last treated six years ago with Lithofin Stain Stop which is a solvent based impregnating sealer which like all sealers will wear off after a few years. Naturally this depends on the amount of wear the floor receives and what tends to happen is this process occurs more rapidly in the high traffic areas leading to an uneven appearance. The best course of action now would be to remove what was left of the sealer and re-polish and seal the floor. During my inspection of the floor I had noticed a number of irregular holes in one of the Travertine tiles which needed filling with a colour matching filler; this worked out quite well and as you can see from the photographs below the result looked entirely natural. After protecting the clients skirting boards with protective film we proceeded to burnish the floor through with a set of Tile Doctor Diamond encrusted honing pads. During the application of the first coarse pad we also added a strong dilution of Tile Doctor Pro-Clean combined with NanoTech Ultra-Clean to aid the removal of sealer residues from the pores of the Travertine. The floor was then rinsed and the soiled solution extracted using a wet vacuum. With the sealer remove we were now able to concentrate on building up the polish on the stone by applying the remaining pads from Medium, Fine through to Very Fine, each lubricated with a little water and ensuring to rinse in-between the application of each pad. With the floor now clean and the polish restored the last step was to protect it so it would keep its appearance for as long as possible. There are a number of solutions for this but for a long durable shine I opted to work Tile Doctor Shine Powder into the Travertine. The powder is applied liberally to the floor and then ground in using a slow speed floor rotary machine fitted with a white or tan buffing pad lubricated with water. The shine on the floor has now been restored and the client has a beautiful and durable finish to their Travertine tiles. Mick Conlon Cambridge Tile Doctor
