Winsor & Newton - Water Colour Permanent Masking Medium

Water Colour Permanent Masking Medium

Permanently isolate delicate watercolor details with masking medium

Isolate delicate highlights or create permanent white lines without leaving raw paper exposed. Winsor & Newton's Permanent Masking Medium bonds with watercolor paper to create water-resistant barriers that stay in place permanently, functioning more like an opaque white paint than traditional removable masking fluid. This opens possibilities beyond simple reservation techniques.

Mix it directly with watercolors to create tinted masking layers that add color while blocking subsequent washes. The medium maintains paint-like handling properties, flowing smoothly from brush or pen for controlled application in fine details, delicate patterns, or precise linear work. Once dry, it resists water completely, allowing you to layer washes freely over masked areas without disturbing protected sections.

Botanical illustrators use it for intricate vein patterns and stamens. Abstract painters build complex layered compositions where early marks remain visible beneath later applications. The permanent nature means you're committing to your marks, but that limitation encourages decisive, intentional mark-making. Apply it wherever you need waterproof white or tinted elements that integrate permanently into your painting's surface rather than peeling away to reveal what's underneath.
