Not only do we carry out the deep cleaning and restoration of all types of natural stone, we can also carry out repairs such as the filling of holes in stone, whether it be limestone, marble or as in this case Travertine. Travertine in particular is prone to a natural process of erosion know as pitting, this results in holes developing that easily fill up with dirt and muck over time and can be a real problem to maintain.
Burnishing and Cleaning a Travertine Tiled Floor
To get the floors clean and restore the polished appearance of the Travertine I decided to apply a set of Tile Doctor diamond encrusted burnishing pads. The process involves the application of four different pads applied in sequence from coarse to very fine, rinsing in-between each pad to remove dirt. As the floor had been installed in the Kitchen and the Hallway it made sense to split the work into two parts and work on each area separately.
The first pad is a coarse 400 grit pad that is attached to a rotary machine running at slow speed and with only water for lubrication. The pad is applied to the stone to removes minor scratches, sealers and dirt. It’s run over the entire floor and afterwards the floor is rinsed with water which is then extracted with the soil using a wet-vacuum.
I then repeated this same procedure with the second pad, which is a Medium 800 grit pad used to remove dirt from minor scratches and holes in the stone. After rinsing again, I went onto the third burnishing pad in the sequence which is a Fine 1500 grit pad that starts to rebuild the polish on the Travertine. I gave the floor another rinse and used the wet vacuum again to extract the water and soil from the floor. The last 3,000 grit super fine pad was then applied with a small amount of water sprayed onto the floor, this last pad really builds a nice shine on the stone.
Sealing a Travertine Tiled Floor
Once the burnishing process was completed the floor was left to dry off fully overnight and I came back the next day to continue with the work. I took a few moisture readings to confirm the floor was dry and then applied a single coat of Tile Doctor Colour Grow to seal the tiles. Colour Grow is a colour enhancing sealer that impregnates into the pores of the stone protecting it from within and improving the natural colours of the stone in the process. I particularly like to use it on Travertine as it really does bring out the brown shades in the stone.
Filling Holes in a Travertine Tiled Floor
Once the first coat of sealant had dried I started the work to fill the holes throughout the installation using appropriate colours of stone filler resin. I purposely delayed doing this until the first coat of sealer was in place in order to prevent excess resin from being absorbed into the tile and causing unwanted staining. There were quite a few holes to fill so it took a while to complete, the filler also needs several hours to dry and harden even when assisted with a fan. Excess filler is then polished off using a 17” rotary scrubbing machine fitted with a white polishing pad and any dust is carefully vacuumed up before applying a second coat of sealer. The floor was then allowed to dry before a final polish with a new 3000 grit pad to achieve a high sine finish.
Once the cleaning process was complete and the first coat of sealant had dried I then commenced the repair work by filling all holes throughout using appropriate colours of stone filler resin, the first coat of sealant is to stop the excess resin from being absorbed into the tile and causing staining, the filler is allowed to dry and harden for several hours assisted with a fan on site. Excess filler is then polished off using a 17” rotary scrubbing machine and a white buffing pad. Any dust is carefully vacuumed up before applying a second coat of sealant. This is then allowed to dry before a final polish with a new 3000 grit burnishing pad to achieve a deep sine finish.
My hall and kitchen floor has been down for 12 years and has been a high traffic area. The Tile Doctor has literally made it look like new again. Holes filled, smooth, shiny and new again! My fully tiled bathroom has also been rejuvenated, wall tiles, shower tiles and floor tiles. The water now beads on the tiles like a freshly waxed car, and the walk-in shower has been perfectly resealed. Money very well spent.
Thank you so much! Mr.J. White, Rushden
