The picture shows an Travertine patio that was installed at a property in Hackney E5 around ten years ago and it had never been sealed. Over the year’s pollution and weather etc had taken its toll on the stone leaving the travertine stained with lichen, dull and grey as opposed to their original white/cream colour. Had the patio been sealed it would have provided some protection from the elements.
We have adopted new working practices since the COVID-19 epidemic so we can work safely inside or outside but given the excellent weather this year this was an ideal and much easier to maintain social distancing.
Cleaning a Travertine Tiled Patio Floor
During day 1 on site I started by sweeping away loose stones and other debris you typically find on patios. Then Tile Doctor Patio and Brick Driveway cleaner was applied neat to the stone and left for two hours. This is a very strong product designed for use by professionals which cuts through the dirt and was ideal for this situation. There are certain precautions you do need to take when using it such as wearing PPE and you must keep it away from ponds etc.
Using water to lubricate, the solution was then scrubbed into the stone using a coarse 200-grit pad fitted to a rotary machine and followed up with a lot of rinsing and extracting with water and a wet vacuum.
To refine the surface after the coarse Travertine the 200-grit pad I followed with 400, 800 and then 1500-grit burnishing pads in sequence rinsing with water and extracting after each pad was applied. This process is known as burnishing and closes the pores in the stone giving it a polished appearance. By this point the Travertine looked way better and we were starting to get the smooth finish back.
Sealing a Travertine Tiled Patio Floor
The client wanted a natural appearance so two coats of Tile Doctor Ultra Seal were applied to seal the stone. Ultra-Seal is an impregnating sealer that soaks into the stone, protecting it from within yet without changing the appearance of the stone leaving a completely natural look.
