Pine board will still produce oil after high temperature drying. Pine board is a kind of wood containing resin and oil, which will volatilize after drying at high temperature, making the wood lose weight and strength. Although drying can make pine board more stable and durable, its oil components will still be secreted, which will cause oil stains on the wood surface and need proper cleaning and treatment. When using pine board, we should fully understand its characteristics and choose appropriate treatment methods to ensure its service life and beauty.
