Craft Gilding Glue is a water-based adhesive that turns translucent and sticky when it dries. Can be used on porous and non-porous surfaces (e.g. paper, plastic, wood, glass, leather, and canvas.) It takes about 15 minutes to a few hours to dry depending on the thickness applied. Instructions: Before applying the glue, make sure the surface is clear of dust and oil. Apply a thin, even coat of glue to the surface and let it dry. The glue will turn translucent when it dries and it will start to become sticky. Apply the gold leaf after the glue has completely dried. Wash the brush or sponge with water and mild soap immediately after use. WARNING: inhaling the vapor can cause headaches, nausea, and irritation to your nose, throat, eyes, and skin. Keep out of reach of children.
