Winsor & Newton Colourless Art Masking Fluid for Watercolours
A colourless, non-staining liquid composed of rubber latex for masking areas of work needing protection when colour is applied in broad washes.
Apply with a brush, colour shaper or ruling pen. Rinse in water immediately after use as masking fluid dries very quickly. Dried rubber masking fluid can be removed carefully with a colour shaper, eraser or finger tips.
Do not apply on damp or soft sized paper, remove as soon as possible after application, and clean brushes with water immediately after use.
