Chartpak Miskit Liquid Frisket Masking Fluid — 35ml Fluorescent Orange, Waterproof Precision

This liquid frisket sits between artist-grade masking solutions and everyday studio supplies: a bright, easy-to-see orange formula that covers precisely and rinses clean from tools. Formulated for use on hard-sized watercolour papers, photographic surfaces, and similar media, it creates a waterproof barrier that you peel or rub away when your paint layer is dry. The vibrant colour helps trace where you've masked, and the 35 ml jar keeps a compact, refillable supply at hand. Made in the USA and labeled to conform with ASTM D4236, it contains natural rubber latex — read the cautions if you have latex sensitivity.

How do I apply this frisket so masked areas stay crisp?

Apply Miskit with a synthetic or natural brush, ruling pen, or masking applicator while the surface is dry and clean. Work steadily: the fluorescent orange lets you track coverage, and thin coats avoid cracking when removed. Allow the fluid to dry fully before watercolour washes to prevent bleeding under the mask.

• Brush or pen application for controlled lines and shapes
• Thin, even layers reduce peeling or flaking
• Dry completely to guaranteed resist of subsequent washes
• Remove gently by rubbing or peeling once paint is cured

Will this frisket damage paper or photographs when removed?

When used as directed on hard-sized watercolour paper and compatible photo papers, the frisket pulls away without tearing or lifting the paper fibres. Removing it after paint has fully dried helps prevent surface abrasion. Test on a scrap or inconspicuous area if working on delicate or valuable originals.

• Safe for hard-sized watercolour papers when applied and removed properly
• Compatible with many photographic and mixed-media surfaces — test first
• Remove only after paints are thoroughly dry to avoid surface stress
• Gently rub or pick at an edge; avoid scraping aggressively

How do I clean brushes and tools after using Miskit liquid frisket?

The formula cleans from brushes, pens, and tools with warm water and soap while the frisket is still wet. Once dried, the rubbery residue can be softened with water then washed away; avoid solvents for routine cleanup. Keep a jar of water and a rag nearby while working to prevent buildup on bristles and nibs.

• Wash wet frisket from tools with soap and warm water
• Soak dried residue briefly in water before scrubbing it free
• Avoid harsh solvents; they are unnecessary for standard cleanup
• Maintain brushes by removing masking fluid promptly after use

Caution: this product contains natural rubber latex which may cause allergic reactions in sensitive individuals. Conforms to ASTM D4236. Store the jar tightly closed to prevent skinning and clean the rim before resealing to maintain freshness.

Who is this for? Artists, illustrators, and hobbyists who need a visible, reliable masking fluid for watermedia will appreciate Miskit’s fluorescent orange visibility and dependable resistance. It's well suited to plein-air painters marking highlights, studio illustrators protecting fine detail, and anyone working on small to medium-sized watercolour sheets or compatible photo papers.
