Masking fluid allows the artist to block out areas so that they do not want to accept colour. Used to create striking white highlights or areas for over-painting at a later stage. 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. An old brush, pen or cotton bud should be used to apply the Masking Fluid as it is extremely difficult to remove from brushes once dry.
