Winsor & Newton Professional Watercolour Mediums-Art Masking Fluid
A removable, slightly pigmented (to make it easier to see on a white background) liquid composed of rubber latex that forms a fast-drying, water-resistant film on watercolour paper and board.
Used for masking areas of work to create highlights or to leave areas for over-painting at a later stage.
Easily removed once dry by rubbing with an eraser, soft tissue or cotton bud
Do not apply on damp or soft sized paper.
Remove as soon as possible after application.
Brushes can be cleaned if washed immediately with water after use, although we recommend a colour shaper, old brush, pen or cotton bud is used to apply the Masking Fluid as it can be extremely difficult to remove from brushes when dry.
