Winsor and Newton Art Masking Fluid is a colourless and non-staining liquid. Composed of rubber latex, it masks areas of work that need protection when the artist applies over colours with broad washes. It it suggested that you do not use this on damp or soft sized paper and that you remove it as soon as possible after its application. Brushed and tools that have been used to apply it can be cleaned from it, but only if it washed immediately with water after use. Size 75ml
