Our expert answers
Hi Bill. I assume you are referring to ‘purpleheart’. Purpleheart naturally darkens over time, to a dark purple colour. To retain the brighter purple colour longer keep the piece out of direct sunlight – UV rays are purpleheart’s enemy. I’d use a water-based lacquer or water-base polyurethane. Any leading brand will do – brands I’ve used include General Finishes, Livos and Sherwin-Williams. Good luck on your finishing.
