Removing Grout Haze from a Travertine Tiled Floor

The photograph below taken at a house in Henley-on-Thames shows a Travertine tiled floor covered with grout haze smears across the surface of the tile. The tiler should of dealt with this after laying the floor however removing grout smears from natural stone is tricky as normally you would use acid but Travertine is very sensitive to acid so I suspect the tiler decided against it in-case the tiles were ruined.

Refurbishing Travertine Tiles

The first step was to give the floor a general wash to remove any grit and to get the grout clean so we started by applying a mild dilution of Tile Doctor Pro-Clean which was spread over the floor with particular attention paid to getting the solution into the grout lines where it was scrubbed in with a stiff brush. Next we removed any trace of product by using a wet vacuum and rinsing thoroughly with clean water. To remove the grout haze and restore the surface polish the floor needed to be burnished which is done using four diamond encrusted burnishing pads applied in the correct sequence of grits from coarse through to super fine. First using coarse pad number 1 we put some clean water on the floor and using our rotary machine slowly burnished the area making sure that we passed over each tile around four times. The coarse pad cuts into the surface grime of the floor and also removes sealers and in this case the grout haze. The resultant soiled water is rinsed away with clean water which in turn is removed using a wet vacuum. This process is then repeated with the remaining pads to hone and polish the floor, rinsing between each pad until a nice polish is built up on the tile. The floor is then given a final rinse and once we were satisfied that all the slurry had been removed we left the floor to dry.

Cleaning Travertine and Limestone Tiles

I returned the next day to seal the Travertine Tile for which I used two coats of Tile Doctor Colour Grow which is an impregnating sealer that will occupy the pores in the stone preventing contaminates getting in there; Colour Grow also brings out the colours in the stone and in this case has done well to bring out the deep brown colours.
