Forms a fast-drying, water-resistant film on watercolour paper and board, easily removed when dry by rubbing with an eraser, soft tissue or cotton bud.

Directions: To be applied directly to paper or board. An old brush, pen or cotton bud should be used to apply the Masking Fluid as it is extremely difficult to remove from brushes when dry.
