Using a sealer is essential to protect gilded surfaces from scratches and tarnishing. Shellac is a cost-effective option that serves as a fast-drying primer; however, it is only suitable for indoor use. On the other hand, Kölner Leaf Protect is specifically designed to seal imitation leaf materials, preventing oxidation without causing any adverse reactions. It is excellent for use on all compositions and genuine leafs, eliminating the risk of discolouration. Once applied, it dries to a clear, semi-gloss finish that preserves the lustre of the underlying leaf. Its unique acrylic formula allows quick drying and easy cleanup with warm water and soap.
