Have a really tricky surface to paint? Ultra Grip/Bonding Agent allows for Fusion™ to adhere to surfaces that are typically not for painting such as a lacquered surface, melamine, thermofoil or laminate. Non toxic, waterbased Ultra Grip™ makes painting the impossible, possible! How to use Ultra Grip™ Apply Ultra Grip™ using a brush, a roller, an applicator pad, or a sponge. No matter what you apply with, be aware that Ultra Grip™ will hold texture and that texture can show through to the final layer of Fusion Mineral Paint. To avoid this, apply Ultra Grip™ in a very thin layer. The product is milky in the bottle, but should be clear when applied. Let it dry 12-24 hours before painting for best results, but you can paint after 2 hours of application. Is Ultra Grip™ a primer?Ultra Grip™ is an adhesion primer, so it helps Fusion stick to slippery surfaces. It's not a transition primer, for painting over dark or bright colours. For that we recommend Fusion Transition or Sterling Mineral Paint. Ultra Grip™ will also not stop bleed through from tannins or rust. For that, we recommend Zinsser BIN shellac-based primer.
