Proper Methods for Preserving Raw Wood

Many people assume that raw wood must be stored in extremely dry conditions, away from wind, cold, and especially water, fearing that moisture will cause mold and decay. However, with the right preservation techniques, wood can even be submerged in water for years without damage. Today, Bestwood is here to share expert methods for preserving raw wood.

1. Drying Methods – Reducing Moisture to Prevent Fungi & Insects
Lowering the wood's moisture content to below 25% helps prevent mold growth and insect infestation.

Natural Drying (Air Drying)
Wood is placed in a drying yard where it dries naturally using environmental conditions. This method is cost-effective and helps reduce warping and deformation.

Kiln Drying (Artificial Drying)
Wood is stacked inside a kiln where heat and steam are introduced to speed up moisture evaporation. This controlled process prevents cracking, warping, and fungal growth while ensuring consistent moisture levels across all pieces, significantly reducing drying time and costs.

2. Chemical Treatment – Enhancing Wood Durability
Beyond moisture control, chemical preservatives are applied to the wood’s cut ends to prevent moisture loss and minimize insect and fungal damage. This technique also reduces end cracks and enhances the wood’s lifespan.

bestwood's Southern Pine Pressure-Treated Wood undergoes regular third-party testing every season, ensuring its quality and effectiveness in resisting decay and pests.

3. Water Storage Method (Timber Ponding) – Long-Term Preservation in Water
In this method, wood is submerged in calm, slow-moving water or storage ponds.
The wood remains in a saturated state, preventing cracks from drying.
High moisture content lowers oxygen levels, making it difficult for decay fungi and wood-boring insects to survive.
Natural oils and resins are gradually released, enhancing durability.
Traditionally, this method was reserved for high-value species such as Taiwan Red Cypress, Hinoki Cypress, and Taiwan Incense Cedar.

Additional Considerations for Wood Preservation
Wood storage techniques vary depending on the specific use case:

Stacking & Storage – Plywood should be laid flat, not stored vertically.
Wood Sculptures & Carvings – Waxing is recommended for religious statues.
Wooden Furniture & Flooring – Regular cleaning and proper maintenance extend lifespan.
By following the right preservation techniques, wood can maintain its strength and beauty for generations. If you need expert advice on wood selection, treatment, or maintenance, Bestwood’s 30+ years of experience ensures we can provide tailored solutions for all your needs!
