After drying (up to 1 hour), it is possible to gild directly for one hour. For a longer lasting or later gilding, the Instacoll Activator (thin layer) reactivates the surface again for the metal adhesion. The activation is dry after a few minutes and keeps the surface treated approximately 1 hour for the respective metal.
