The Winsor & Newton Art Masking Fluid is a popular choice for artists who want to protect certain areas of their watercolor paper while applying color washes.

The fluid dries to a matte finish and is washable, making it easier to remove once the painting is dry. It peels off cleanly without damaging paper but should only be applied on dry, well-sized paper to avoid tearing or lifting the surface.
