This thin fluid glue typically dries within 10 -30 minutes depending on the thickness of application. Apply with a paint brush, wash brush while still wet. Once glue is dry and clear, press your foil transfer sheet, metal leaf or flakes onto the tacky surface. Remains tacky for several hours and up to several days in humid environments. You can also apply foils, glitter, mica powders, chalk pastel dust etc. while wet if detail precision is not required.
Ideal for non-porous surfaces like picture frames, polymer clay and hard objects. This is a very thin liquid, which means it can absorb into the fibers of very absorbant papers like watercolor paper. That is not ideal, as it needs to sit on top of the surface to remain tacky (there is a thick formula version for that use). You may be able to use it best on paper if the paper is sealed first, such as clear acrylic medium, or by doing multiple layers of adhesive. Works with most semi-absorbant surfaces such as canvas or leather. However, it is made for non-porous surfaces where the thin glue can sit on the surface allowing for gilding fine details (like designs carved into a picture frame or a sculpture).
If you are working with porous surfaces, you may be interested in the thick version of this or deco foil glue instead
