Catalyzed varnish is a durable finish but still needs proper care. Avoid paper towels, which can scratch the surface, and instead use a soft cloth. For the first 30 days, handle with extra care while the varnish continues curing. After this period, maintain a humidity level between 40% and 45% to prevent wood movement, which can cause unsightly gaps. A thoughtful care routine preserves the varnish’s shine and protects against everyday wear.
