Due to the high adhesive strength of the binder, acrylic paint and the various gel mediums are ideally suited for working with different materials. A prerequisite for good adhesion is that the surfaces of the materials to be glued are grease-free and somewhat absorbent. The most durable result is achieved if the materials are completely encapsulated by the paint or gel, especially in connection with adhesion when it concerns less porous materials such as sand, pebbles, glass, etc., but also more porous materials such as paper and cardboard are then protected against harmful external influences. If the natural colour of the material must remain visible, use one of the gel mediums.
