This mouldy filled Travertine tiled bathroom was located in a house in Glasgow and as you can see from the photograph below was completely covered in mould right round the whole bathroom, there was also some staining from the dyes in soap etc.
Cleaning a mouldy Travertine tiled bathroom
Firstly we cut out all the mouldy silicone with a sharp knife and once this was done we mixed a strong solution of Tile Doctor Pro-Clean in a spray bottle and sprayed the cleaning product onto the walls, we used a spray as the air makes the solution lighter and stick onto the tile. Once this was done the Pro-Clean was scrubbed into the stone with stiff brushes and a lot of elbow grease using small nail brushes to allow us to get into all the tiny dimples in the filled travertine. Travertine is a natural product so Pro-Clean being a strong alkaline product is ideal for cleaning natural stone as even mildly acidic cleaners can eat away at the stone.
Sealing Travertine Tiles
Once the tiles were cleaned they were then sealed with two coats of Tile Doctor Colour Grow which is a colour enhancing sealer which is designed to protect the stone whilst lifting the colours out.
The grout was still discoloured following the cleaning process so to get it looking fresh again and after the stone was sealed we applied white grout colourant which brought the grout back to perfect white. This was done after sealing to stop the colourant absorbing into the tiles when they were un-protected making it easier to wipe off. The grout colourant we use looks natural and also forms a barrier over the grout making it easy to clean.
Once everything else was complete we finished the job off by renewing the white silicone up the corners of the walls and around the bath; the end result was a huge transformation that both us and the customer were more than happy with.
