It's a special sealer for gilding, natural resins based. It can be applied on 2K Zapon Basecoat, Acrylic Gesso Primer or Natural Bole, as insulator and adhesion promoter of the acrylic Water-based Goldsize for imitation leaf application. It can be applied also before solvent based and oil based goldsize. When clear, it doesn't modify the color of the basecoat; when colored, enhances the warmth of the imitation leaf.
