Mont Marte Masking fluid is a paint resisting medium that acts as a mask to keep watercolour paper white. Plus, it has a non-staining formula with a slight yellow tint, so you can see exactly where youre going with it. Once the masking medium is dry and youre finished painting over it, peel or erase to reveal the crisp edges and clean white paper underneath.
