Maries Masking Fluid / Gum (100ml) MW-1100
Marie's Art Masking Fluid is used to mask areas of the paper, making them resistant to water colour. Sections treated with Art Masking Fluid must be allowed to dry before overpainting. Once dry, these areas remain protected and cannot be penetrated by colour. Do not apply on damp or soft sized paper. Remove as soon as possible after application....
