Its clear formula improves adhesion while allowing the original surface to remain visible, making it ideal when you want to preserve the natural appearance of your project. Apply an even coat with a brush or sponge, then allow it to dry completely before adding paints, pastes, papers, or other decorative products. Suitable for use on wood, cardboard, MDF, canvas, metal, glass, and many other surfaces. Jar contains approximately 150 ml.
