Vallejo Paint - Ultra Matt Polyurethane Varnish 60ml - 26653

Yes, it is designed to be compatible with water-based acrylics, enamels, and lacquers. However, always test on a small, inconspicuous area first to ensure compatibility with your specific paint system.

The varnish is touch-dry within minutes, but allow at least 30 minutes to an hour between coats and 24 hours for a full cure, depending on environmental conditions like humidity and temperature.

Yes, it is suitable for sealed resin 3D prints after the resin has been properly cleaned and cured. It provides a protective matte finish.

Immediately after use, flush your airbrush with water. For stubborn residue, use a dedicated acrylic cleaner or a 50/50 mix of Isopropyl Alcohol and distilled water.

Vallejo Polyurethane Ultra Matt Varnish is formulated to resist yellowing. However, prolonged exposure to direct UV light can affect any clear coat over extended periods.

While it is water-based and has lower VOCs than solvent varnishes, it is still recommended to use it in a well-ventilated area to ensure optimal drying and performance.

Apply varnish in very thin, even coats, using long, smooth strokes. Ensure the varnish is slightly thinned if it feels too thick. Allow sufficient drying time between coats.

This can happen if applied too thickly or in humid conditions. Ensure adequate ventilation and a dry environment. If applied to acrylic paints, ensure they are fully cured. Consider a very thin second coat once the first is dry.

Start with a 10% dilution of distilled water or Vallejo Airbrush Thinner. Gradually add more thinner in small increments until the desired consistency for smooth spraying is achieved. Test on a spare part first.

Ensure the bottle was shaken thoroughly before use to reintegrate the flattening agents. The surface it is applied to should also be clean and free of any residues that might cause a sheen.
