Dux Quick Dry Gilding Size is a quick setting oil-based leaf adhesive specially designed for gilding all types of metal leaf on a wide variety of substrates. Tack will be reached in approximately 1-2 hours and remain tacky for an additional 1-2 hours for gilding, depending on atmospheric conditions. Warmer temperatures will reduce tack time and the open time for gilding, while colder temperatures will increase the time.
