How does the wood grain structure influence preservation?

Tight grain patterns play a crucial role in the effectiveness of preservative penetration. When wood has a tight grain structure, it typically has fewer voids or gaps between the fibers, which can facilitate a more even and thorough absorption of preservatives. This means that the protective chemicals can penetrate deeper into the wood, thus enhancing the material's durability against environmental factors, fungi, and insect damage.

In contrast, coarse grained woods, while they may absorb some preservatives, often have larger gaps that can lead to less uniform penetration. This can result in areas of the wood being under-protected, which is a concern for long-term preservation. The belief that all grain patterns absorb preservatives equally is misleading; variations in grain structure significantly impact how well a preservative can be retained and utilized by the wood. Additionally, the idea that tight grains require less preservative overlooks the fact that while they may absorb effectively, they still need an adequate amount of preservative to ensure full protection.
