How to conduct moisture and mildew proof treatment for wooden venetian blind slats?
Moisture and mildew proof treatment for wooden venetian blind slats is crucial for extending their service life, preserving their appearance and ensuring the health of the usage environment. Below are the detailed treatment methods:
Moisture content control: Selecting wood with an appropriate moisture content is the foundation of moisture and mildew proofing. Generally, the moisture content of wood should be controlled between 8% and 12%. Excessively high moisture content makes wood prone to absorbing external moisture and developing mildew, while overly low moisture content may cause wood to crack and split. The moisture content of wood can be adjusted through kiln drying, air drying and other methods.
Wood species: Prioritize wood with natural durability, such as teak and merbau. These types of wood contain natural oils or antibacterial components that provide a certain resistance to mildew and moisture. For example, teak contains oily substances that form a protective film on the wood surface, slowing down moisture penetration.
Cleaning: Thoroughly clean wooden venetian blind slats to remove surface dust, dirt and impurities before any treatment. You can sweep the slats first and then wipe them with a damp cloth to ensure a clean and tidy surface.
Repairing: Inspect the slats for defects such as cracks and wood-boring holes. Small cracks can be filled with wood glue and wood shavings; wood-boring holes should be treated with insecticide before filling. The filling material should be close to the color of the wood to ensure a consistent appearance.
Sealing effect: The main function of primer is to seal the wood surface and prevent it from absorbing excessive water and moisture in the air. Choose a primer with excellent sealing performance, such as water-based sealing primer or oil-based sealing primer. Ensure uniform application without omissions when painting the primer. Generally, 2 to 3 coats are required, with sufficient drying time for each coat before applying the next.
Adhesion enhancement: Primer also improves the adhesion between subsequent coatings and the wood surface. Lightly sand the wood surface to remove burrs and uneven areas before primer application, which can boost the primer's adhesion.
Moisture proof function: Select a topcoat with moisture proof properties, such as waterproof topcoat and moisture resistant topcoat. These topcoats form a dense protective film on the wood surface to block moisture penetration. There are various types of topcoats available, which can be chosen according to the usage environment and requirements of the wooden venetian blind slats. For instance, in high-humidity environments like kitchens and bathrooms, a topcoat with stronger waterproof performance should be selected.
Mildew proof function: Some topcoats are added with mildew inhibitors to inhibit the growth of mildew. Pay attention to the coating thickness and uniformity when applying the topcoat. Generally, 2 to 3 coats of topcoat are also needed to achieve a good moisture and mildew proof effect. Meanwhile, take into account factors such as the drying time of the topcoat, ambient temperature and humidity to ensure the full curing of the topcoat.
Desiccants can be placed inside wooden venetian blind slats to absorb excess moisture. Common desiccants include silica gel desiccants and calcium chloride desiccants. Silica gel desiccants are non-toxic, odorless and chemically stable, making them suitable for indoor use. Desiccants can be placed in special small bags inside the slats or directly in the hollow cavities. Inspect and replace desiccants regularly to ensure their moisture absorption effect.
For wooden venetian blind slats that are prone to mildew, internal treatment with mildew inhibitors is applicable. Mildew inhibitors can penetrate into the wood through soaking, spraying or injection. For example, immerse the slats in a mildew inhibitor solution for a certain period and then air dry them, or use professional spraying equipment to evenly spray the mildew inhibitor inside the wood. This method can reach the inner part of the wood and play a preventive and inhibitory role against mildew.
Choose a suitable installation environment for wooden venetian blind slats. Avoid installing them in areas with excessively high humidity and poor ventilation. For example, in high-humidity areas such as bathrooms, doors and windows with better waterproof and moisture proof performance should be installed or additional moisture proof measures should be taken. At the same time, ensure the structural stability of the installation position to prevent the slats from loosening due to deformation caused by moisture.
Keep the wooden venetian blind slats clean and dry during daily use. Wipe the slat surface with a clean damp cloth regularly to avoid long-term residue of dirt and water stains. Wipe off water droplets or moisture on the slat surface in a timely manner if found. In humid seasons, use a dehumidifier or the dehumidification function of an air conditioner to reduce indoor humidity and lower the risk of the slats getting damp and mildewed.
