Winsor & Newton™ 75mL Watercolor Permanent Masking Medium

Apply to paper where you want to preserve its original color. Protects the areas you do not want to paint. For masking areas of work needing protection when color is applied in broad washes. Use an old brush to apply masking fluid. Do not use on damp or soft-sized paper. Apply medium to areas you want to protect. Wash brush immediately, before the medium dries. After it has dried on your paper, the covered areas will not absorb any color. Creates a permanent, transparent and water-repellent film.
