A common question regarding Shou Sugi Ban façades is whether they need regular maintenance. Generally, the answer is no. In Japan, it’s customary to leave Yakisugi façades untreated after installation, as the natural weathering process is considered aesthetically pleasing. However, all wood, including Charred Wood, will weather over time. Carbon layer overtime will loose its protection due to weathering and eventually will turn grey due to UV exposure.
These changes are mainly cosmetic and depend on factors like location, climate, and surface exposure. To maintain the original look of your Yakisugi, applying wood oil or a coating can help slow down the greying process, with recommended touch-ups every five to ten years. This straightforward maintenance requires only a brush, without the need for sanding, staining, or priming. If you need more advice, feel free to reach out.
