Essential Wood Preserving Tip:
To ensure optimal wood preservation, it is crucial to treat all wood, both new and old, with a fungicidal wash or multicide wood cleaner before applying a wood preservative. This eliminates existing spores in the wood grain, preventing the establishment of mold, algae, and fungi. Although wood preservatives offer protection against future growth, they may not effectively eradicate already established spores within the wood.
