Winsor & Newton Watercolour Medium Art Masking Fluid 250ml
Winsor & Newton Art Masking Fluid is a lightly tinted liquid, used to temporarily mask and preserve the paper when applying color, as it prevents the paint adhering to the paper. Especially useful when trying to create fine details.
Do not apply on damp or soft sized paper. Remove as soon as possible after application. Brushes can be cleaned with water if washed immediately after use.
