Dux Slow-Set Size is the ideal choice for gilding projects requiring extended working time. This solvent-based oil size reaches proper gilding tack in 10-12 hours and maintains an open window for applying genuine or metal leaf for approximately the same duration. Metal leaf application typically has a shorter open time. Perfect for detailed work or larger surfaces where rushed application isn't an option. Allow a minimum of one week curing time before sealing. One quart size.
