Sioo:X Light Grey is an advanced wood protection treatment that gives timber a natural, silver-grey weathered appearance while enhancing its durability. Inspired by the natural aging of wood, it uses a patented silicate-based formula that penetrates deeply into the timber, forming a protective barrier against moisture, UV radiation, and biological decay. Over time, the treatment continues to cure and develop its distinctive light grey tone, offering a long-lasting, low-maintenance finish that is both environmentally friendly and aesthetically refined.
