U.S. Art Supply Art Masking Fluid, 125 ml (4.2 oz) Bottle - Artist Drawing Gum Liquid Frisket Mask - Watercolor Medium
Mask areas of artwork that need protection when color is applied
A premium art masking fluid that's made with liquid rubber latex that's lightly pigmented. The fluid dries to a light cream color, so it can be differentiated from white backgrounds, as it allows you to see exactly where you've masked. A high quality watercolor medium that conforms to ASTM-D4236.
It's ideal for use by watercolor artists
Quick drying, non-staining liquid frisket mask is easy to apply using a brush, pen or nib. Brushes, pens and nibs can be washed off with soap and water. The dried masking fluid should be removed as soon as possible after use, and it is easily removed by rubbing it off by hand or with a soft eraser. The masking fluid works best on sized paper and is ideal for use by watercolor artists, as it's great for overlying applications of watercolors, gouache and inks. Do not apply masking fluid on damp or soft paper.
