How does eucalyptus wood’s tannin content affect staining or finishing?
Eucalyptus wood is prized for its durability and attractive grain, but its high tannin content can pose challenges for staining and finishing. Tannins, natural compounds found in the wood, often react with certain finishes, leading to discoloration or uneven absorption. When applying water-based stains or finishes, tannins may bleed through, creating blotchy or darkened areas. To prevent this, use a tannin-blocking primer or shellac-based sealer before staining. Oil-based finishes tend to interact less with tannins, offering a more uniform result. Sanding the wood thoroughly and testing finishes on a small area can also help achieve a smooth, professional look. Understanding these factors ensures a successful project when working with eucalyptus wood.
