Mont Marte Masking Fluid, 120ml, Easy Peel

Mont Marte Masking Fluid is an artist-grade liquid mask designed for watercolor and mixed-media. It creates a removable barrier on your paper to protect white areas and fine details while you paint, keeping those areas clean for precise results.

It works well with watercolor, ink, and acrylics on paper. The formula is flexible enough for layering, making it ideal for detailed masks and intricate shapes.

Apply a thin, even layer with a brush or pen. Avoid overloading or flooding the area, and let it sit smoothly on the surface to prevent cracking or peeling later.

Masking fluid dries quickly to a rubbery finish. Allow it to dry completely before painting over it. You can apply additional masking fluid in layers once previous layers are dry to preserve more areas.

Peel it off gently once fully dry. It should come away cleanly without leaving a residue on the paper when used as directed.

Yes. The masking fluid is designed to hold back the masked areas so you can apply your paint freely, then reveal clean, white spaces or protected details after removal.

Yes. Its non-staining formula and clean removal help beginners, while still delivering professional results. As with any art product, use in a well-ventilated area and keep away from eyes and mouth.

Keep the cap tightly closed and store upright in a cool, dry place away from direct heat or sunlight to prevent the liquid from drying out or becoming unusable.

Compared to alternatives available on Fepy, Mont Marte’s 120ml version emphasizes easy application, quick-dry performance, and clean removal. For smaller or larger volumes, you can compare the listed options: Mont Marte Masking Fluid 60ml (for travel or smaller projects), Daler-Rowney Masking Fluid (different viscosity and coverage), and Winsor & Newton Masking Fluid (premium brand with its own characteristics). See the specific product pages for exact details:

It's great for watercolor washes with fine detail work, preserving white highlights in botanical illustrations, architectural drawings, and any piece where you want crisp masking of delicate areas.

Ensure it was fully dry before painting over it. If it’s stubborn, gently re-dry in a warm, ventilated area, then peel away slowly. If residue remains, a soft rubber of eraser or a gentle wash with water can help remove any remaining film.

Coverage depends on how thickly you apply the fluid and the size of the masked areas. The 120ml bottle provides multiple masking sessions across several projects, especially if you mask fine lines and smaller details rather than large blocks.
