Dux Quick-Dry Sizewill reach tack in approx. 2 hours and will remain open for gilding for 2 to 3 hours. In very dry and warm environments, it may reach tack in as little as 1 hour and the open time for gilding may be greatly reduced. It produces excellent results with genuine and metal leaf and is recommended for small projects or when time is limited. Allow to cure for 24 hours before sealing.
