Markal Paintstik Solid Paint Marker — Fluorescent Red Pack of 12 for Rough, Oily & Wet Surfaces, UV-Visible

These Paintstiks are a compressed solid paint in a convenient stick form that delivers vivid, long-lasting fluorescent red marks on metal, wood, concrete, rubber and many other tough substrates. Supplied as a pack of twelve, they fit standard Markal no. 101 and no. 102 holders for controlled application and reduced hand fatigue. The formulation performs in a wide temperature span and is designed for high-visibility layout, inspection, and colour-coding tasks.

How does the Paintstik perform on rough or dirty surfaces?

The solid paint core is dense and durable, so it transfers reliably across textured, greasy, or wet materials where pens and liquid markers fail. Its body lays down a generous, opaque stroke that resists smearing and stands out under industrial lighting.

• Marks through oil and light water contamination for clearer lines.
• Opaqueness hides substrate colour and texture for consistent visibility.
• Good adherence to metal, concrete, plastic, and wood.
• Fluorescent pigment increases visibility in low-light and inspection settings.

Will the fluorescent red show under black light and typical shop lighting?

Yes — the Paintstik’s fluorescent pigments react under ultraviolet light for a bright glow, while remaining highly visible under standard workshop and daylight conditions. That makes it useful for QC checks, night work, and marking inspection points that need quick identification.

• Glows under black light for easy UV inspections.
• High-visibility colour under fluorescent and natural light.
• Consistent appearance across varied lighting scenarios.

How do I use the Stick and holders for best results?

Insert the Paintstik core into a compatible Markal holder (no. 101 or 102) to stabilise the stick and control stroke width. Use steady pressure and a single pass for a bold line; rotate or exchange cores as they wear down to maintain line quality.

• Fits Markal no. 101 and no. 102 holders for grip and precision.
• Apply steady pressure for continuous, even marks.
• Replace core when tip narrows to preserve stroke width.
• Store capped or in holders to prevent contamination and breakage.

What temperature and material limits should I expect?

The Paintstik remains usable in a broad temperature window, making it suitable for indoor and outdoor tasks in variable climates. It bonds to a wide range of substrates but is intended for marking rather than long-term decorative coating.

• Functional range: -50°F to 150°F (-46°C to 66°C).
• Works on metal, wood, glass, plastic, concrete, rubber, cardboard, and paper.
• Not meant as a structural sealant or permanent paint finish.

Who is this for: Professionals and tradespeople who need durable, high-visibility layout and inspection marks — riggers, welders, construction crews, fabricators, inspectors, and maintenance teams will find these fluorescent Paintstiks useful. The pack of twelve keeps supplies on hand for job sites and busy shops where fast, reliable marking on rough, oily, or damp surfaces is essential.
