Dux Slow Set Oil Size is designed for projects that require an extended open time for gilding, making it perfect for intricate work or large-scale projects. Unlike quicker-drying alternatives, this oil size takes 10-12 hours to achieve the appropriate tackiness, allowing for a more flexible and forgiving application period. It is compatible with both genuine and imitation metal leaf, ensuring excellent results. For optimal performance, a minimum curing period of one week is recommended before applying any sealant.
