Aquafine Art Masking Fluid is a fast-drying medium that protects white areas in your watercolour paintings for later overpainting. It forms a water-resistant film that can be removed easily once dry by rubbing with an eraser, soft tissue, or cotton bud.

For application, use an old brush, pen, or cotton bud, as the fluid is difficult to clean from brushes once dry. If left standing, a skin may form on the surface, but breaking it reveals the fluid beneath. The consistency may thicken over time, so remove it from your artwork promptly.
