As with all natural stone products our stone benefits from a simple clean and maintenance routine. Frequency will depend on the type of installation and its location.

  • We recommend regular sweeping to remove garden / surface debris when dry, washing with a mild detergent, and rinsing with clean water.
  • Choose your brush wisely; steel wool or wire brushes for example can damage the stone leaving marks on the surface.
  • Algae, lichens and other flora will develop in damp and shaded areas.¬† These spots may require cleaning on a more regular basis; a mild biocide solution will help the cleaning process and should be applied annually.
  • We would not recommend the use of jet or pressure washers. While they clean the stone effectively they can damage the surface of the stone and jointing, and destabilise the installation.
  • If a deep, more intensive clean is required then we suggest contacting a specialist cleaning contractor. ¬†Please contact us for proven and recommended suppliers.
  • It is important to acknowledge that a general toning down of colour will occur due to the natural weathering process, and is perfectly normal.
  • Surface treatments can be applied to preserve the appearance and assist cleaning of the stone. We recommend that the customer seek advice from the treatment manufacturer prior to use.
