How does temperature affect wood preservatives?

Higher temperatures enhance the penetration and effectiveness of wood preservatives due to several factors related to the chemical and physical properties of the preservatives and wood.

When temperatures rise, the viscosity of liquid preservatives typically decreases, allowing for better flow and greater penetration into the wood fibers. This improved flow enhances the ability of preservatives to fill voids and cavities within the wood, leading to more effective protection against decay and insect damage. Additionally, elevated temperatures can increase the reactivity of certain chemical components in the preservatives, promoting better bonding with the wood substrate.

Thus, warmer conditions facilitate deeper absorption and more effective treatment, ensuring that the wood is well-protected against environmental threats. As a result, this makes higher temperatures particularly beneficial during the application of wood preservatives.
