One. How to repair mold on plywood.
Wood has a porous structure, making it susceptible to absorbing moisture from the air, leading to mold growth. If particleboard develops mold in humid environments, such as during the rainy season, a wood mold remover can be used to eliminate the mold and restore the wood's original appearance.

1. Before operation, thoroughly clean any debris on the surface of the particleboard. Use a cleaning agent, applying it by brushing or spraying. When mold or slight mold growth appears on the particleboard surface, such as mold spots or mold points, use a brush to evenly apply or directly spray the cleaning agent onto the moldy surface of the particleboard. Place it in a well-ventilated area to air dry naturally. After the mold on the particleboard is eliminated, proceed with subsequent processing. For severely moldy particleboard with a long mold growth cycle, repeat the treatment twice, applying the cleaning agent evenly with a brush every 12 hours. Ensure the particleboard surface is slightly damp during operation.
2. For mild mold growth, such as mold stains and spots, the wood treatment agent can be used to soak the affected wood. After soaking and drying, the mold will be removed. For severe mold growth with a prolonged duration, soaking for approximately 30-60 minutes will eliminate the mold.
3. If mold is severe, it is recommended to replace the plywood, as the environmental properties of plywood are generally poor, and mold can potentially pose a health risk.
Two. How to treat black spots on the surface of plywood.
Common causes for black spots appearing on the surface of plywood include:* The wood is not dry enough, leading to mold growth.* Natural drying causes moisture in the adhesive to remain, leading to mold growth.
Methods for treating black spots on particleboard: All boards are dried, and the moisture content is controlled to be no more than 10%; use high-frequency lamination process to quickly volatilize the moisture in the boards after forming.
