Lichen, moss and other plant-based staining is a common sight on patios exposed to the UK climate. For many property owners, it’s a very difficult task to keep patios looking great in the face of the natural effects of the environment. However always happy to help Tile Doctor is available to provide the professional cleaning and sealing needed on a regular basis.
This Sandstone tiled patio in Rushden was certainly a prime candidate for restoration. Not only was it completely covered in lichen and moss, but it was also cracked in parts and missing grout. The patio would therefore need not only cleaning and sealing, but also re-grouting.
Cleaning a Stained and Damaged Sandstone Patio
To begin the restoration, I opted to power jet wash the entire area to remove as much of the initial layers of moss. Then, I mixed a strong dilution of Tile Doctor Pro Clean, which is a powerful and reliable alkaline cleaner suitable for use on both internal and external natural stone tiles. This was applied liberally to the patio and scrubbed into the stone to cut through the particularly stubborn stains. The two photos below show the fantastic result.
Re-grouting and Sealing a Sandstone Patio
After completing the cleaning phase, I allowed the patio to dry completely overnight before returning to re-grout the entire area with mortar. To finish off I applied a fresh sealer in the form of Tile Doctor Seal and Go Extra, which an acrylic-based, fully breathable sealer appropriate for outside use.
The below pictures show the final result. As you can see, it was a complete transformation – and my very happy customer will agree! With the right products and methods, it’s possible to bring new life back to weathered patios.
