Zieler : Artists Masking Fluid : 60ml : Blue

Zieler Artists Masking Fluid is a blue pigmented liquid made from rubber latex and pigment, used to mask areas of work that need to remain protected while watercolour is applied in broad washes. The blue tint makes it easier to see on white paper than traditional white masking fluid, while working in the same way.

It can be applied to paper with a brush or pen and, once dry, removed with an eraser. For best results, it should not be applied to damp or soft-sized paper, and it should be removed as soon as possible after use. Brushes can be cleaned with water if washed immediately after application.
