Charred timber cladding, also known as Shou Sugi Ban, is an attractive and durable choice for exterior timber cladding. The process of charring timber not only gives it a stunning, deep-black aesthetic but also improves its natural resistance to weathering, insects, and rot. While charred timber cladding is relatively low maintenance, it still requires some care to ensure it remains beautiful and lasts for many years. In this blog, we’ll outline key maintenance tips to help you keep your charred timber cladding in excellent condition.
Understanding the Benefits of Charred Timber Cladding
Before we dive into maintenance tips, it’s important to understand why charred timber cladding is such a popular choice. The traditional Japanese Yakisugi technique, which involves burning the surface of the wood, creates a protective layer that enhances the timber’s durability. This charred layer helps prevent moisture absorption, makes the wood more resistant to fire, and offers protection from pests.
One of the key advantages of charred timber is its ability to weather naturally, requiring far less upkeep than untreated wood. However, like all exterior surfaces, it benefits from regular inspection and cleaning to maintain its appearance and performance.
1. Regular Inspections Are Key
While charred timber cladding is highly durable, regular inspections are essential to catch any potential issues early. We recommend inspecting your cladding at least once or twice a year, especially after extreme weather conditions such as heavy rain, snow, or high winds.
Look out for signs of damage, such as cracks, chips, or areas where the charred surface may have worn away. If you notice any exposed wood, these areas may require additional treatment or sealing to maintain the protective benefits of the charred layer.
2. Cleaning Your Charred Timber Cladding
Charred timber cladding naturally repels dirt, but occasional cleaning can help keep it looking its best. To clean your cladding, follow these simple steps:
- Use a soft brush or broom to remove any loose dirt or debris from the surface. Avoid using anything too abrasive, as this could damage the charred layer.
- For more stubborn dirt, you can use a mild detergent mixed with water and gently scrub the surface with a soft cloth or sponge.
- Rinse thoroughly with clean water to avoid leaving any soapy residue.
Avoid using high-pressure washers, as these can damage the charred surface, reducing its effectiveness and longevity.
3. Protecting Against UV Exposure
While the charring process enhances the wood’s resistance to many environmental factors, prolonged UV exposure can still cause the charred surface to fade over time. If you notice that your cladding is losing its deep black colour, applying a UV-resistant finish can help restore its appearance and protect the wood underneath.
There are several specialist oils and treatments designed specifically for charred timber, which can be applied to refresh the surface and add additional UV protection. This type of maintenance typically only needs to be done every few years, depending on the level of sun exposure your property receives.
4. Re-Charring for Long-Term Maintenance
One of the most unique aspects of charred timber cladding is that it can be re-charred if the surface becomes too worn or damaged. This process involves carefully burning the surface of the wood again to restore its protective layer. While re-charring is not a frequent requirement, it can be a great way to extend the lifespan of your cladding and keep it looking pristine for many years.
We recommend hiring professionals to handle any re-charring to ensure that it’s done safely and effectively.
5. Sealing and Finishing
Depending on your aesthetic preference and the environmental conditions in your area, you may want to apply a sealer to your charred timber cladding. Sealers provide an additional layer of protection against moisture and UV rays. However, many people prefer the natural, untreated look and choose to let the timber weather naturally.
If you decide to use a sealer, be sure to choose a product designed specifically for charred wood to avoid damaging the charred surface.
