The Sennelier Drawing Gum (commonly known as Masking Fluid or Liquid Frisket) is an essential tool for watercolor and ink artists looking to preserve crisp, white areas or specific details on their paper. Packaged in a convenient 75ml bottle, this high-quality fluid is formulated by Sennelier, a brand trusted by fine artists since 1887

This masking fluid applies easily and dries quickly to form a protective film. Once your paint or ink is completely dry, the rubber cement film can be gently removed by rubbing with a finger or a dedicated gum eraser, revealing the clean, unpainted paper underneath. It’s the perfect solution for creating highlights, sharp edges, and detailed negative spaces.

Directions for Use:

1. Application: Shake well before use. Apply the masking fluid directly to dry paper using a clean brush, ruling pen, or applicator. For best results and to protect your brushes, dampen the brush hairs with soap and water before dipping into the fluid, and wash immediately after use.
2. Drying: Allow the fluid to dry completely until it forms a solid, rubbery film. This usually takes a few minutes depending on application thickness.
3. Painting: Apply your watercolor or ink washes over the top of the dry masking fluid.
4. Removal: Once your paint layer is fully dry, gently peel or rub the masking fluid off with your finger or a soft rubber cement pickup/eraser. Do not leave the fluid on the paper for extended periods (e.g., more than a few days) to prevent staining or tearing of the paper surface.
