A non-removable, water repellent liquid designed for masking specific areas of paper, making them resistant to water and colour. When dry, the medium will repel washes and omit are as, preserving the original colour. Excellent for detail. Apply directly to the paper or tint with small amounts of watercolour. Allow to dry completely before overpainting. Show more
