What is Mont Marte Gloss Varnish?
Mont Marte Gloss Varnish is a clear, glossy finish that you can apply over your paintings or craft projects to protect them from dust, UV rays, and moisture. I love how it enhances the colors, making them look vibrant and fresh, while adding a professional shine.
Why I Chose Mont Marte Gloss Varnish

Key Features to Consider
- Gloss Finish: The high-gloss effect really makes my paintings pop, especially acrylic and oil artworks.
- Durability: It offers a tough, protective coating that helps my pieces withstand handling and environmental factors.
- Application: I usually apply it with a soft brush or spray, and it spreads smoothly without streaks or bubbles.

Then, I apply thin, even coats—usually two coats for the best protection. Between coats, I let it dry completely. Ventilation is important since even though it’s water-based, I prefer a fresh workspace.
Things to Keep in Mind
- Always test the varnish on a small, inconspicuous area or a practice piece before applying it to your final artwork.
- Avoid applying too thick a layer to prevent drips or uneven gloss.
- Store the varnish in a cool, dry place to maintain its quality.
