1、Apply a coat of paint to the surface
Charcoal wood is processed in a high-temperature environment, where the polysaccharides (cellulose) within the wood decompose at high temperatures, forming monosaccharides that adhere to the wood surface. As the surface rapidly grows, it is prone to further decay. Additionally, charcoal wood has a weak ability to absorb and retain water, but a strong ability to absorb free water. To mitigate these effects, it is recommended to apply three coats of paint to the surface of the charcoal wood to protect it.
2、Regular cleaning

Regular cleaning is essential for both outdoor and indoor use of charcoal wood. If charcoal wood is not cleaned regularly, it may develop cracks and minor deformations, affecting its structural strength. When cleaning charcoal wood, it is generally recommended to use a brush and a specialized cleaning agent.
3. Regular maintenance
Due to its use in outdoor environments, charred wood is prone to cracking and minor deformation, which is a normal phenomenon and does not affect the structural strength.
based on the application environment of charcoal wood, maintenance should be performed approximately every 1 to 1.5 years, typically using specialized water-based or oil-based wood coatings.
