Winsor & Newton Watercolour Art Masking Fluid is a latex-based masking liquid which is slightly yellowish so easy to see. It can be easily removed with an eraser.
This Winsor & Newton Watercolour Art Masking Fluid should be used when you want to use colour washes but not cover key details. It makes the paper water-resistant and can be used over previously painted areas, or on white paper. It acts like a protective skin.
NB Do not use on damp or unsized paper.
Price per bottle.
