15mm Wide Tip Liquid Chalk Markers for LED Chalkboards,Glass,Menu Boards & Window Signage

Bold. Bright. Wipe-Clean. No Dust.

Traditional chalk crumbles, smears, and leaves a dusty haze across your board and your clothes. Liquid chalk markers eliminate every one of those problems.

No dust. No residue. No mess.

Whether you’re running a café menu board, decorating a retail window display, or creating eye-catching LED signage, this marker delivers professional results without professional complexity.

Frequently Asked Questions

Q: What surfaces do these markers work on?

A: These markers are designed for non-porous surfaces: LED chalkboards, glass, mirrors, acrylic, sealed chalkboard panels, and glazed ceramics. They are not recommended for porous surfaces such as raw wood, uncoated paper, or unsealed chalkboard paint — the ink will absorb and become difficult or impossible to remove.

Q: How do I erase the marks?

A: Simply wipe with a damp cloth or wet paper towel. For stubborn marks or dried ink, use a slightly wet sponge with light pressure. On glass, a window cleaner spray works perfectly. No solvents or special erasers needed.

Q: Do the colors glow on LED boards?

A: Yes. The neon pigment formula is specifically optimized to fluoresce under LED backlighting, producing vivid, glowing color on illuminated chalkboards. Results are most dramatic in dim or dark environments.

Q: How do I activate the marker before first use?

A: Shake the marker well for 30 seconds, then press the tip down firmly on a scrap surface several times until ink flows to the tip. This primes the valve and ensures smooth, consistent ink delivery from the first stroke.

Q: Is the ink dusty or messy like traditional chalk?

A: No. The liquid chalk formula produces zero dust. It is completely dust-free during use, making it safe and clean for food service counters, children’s classrooms, and any environment where chalk dust is a concern.

Q: What line widths can I achieve with the 15mm chisel tip?

A: The chisel tip gives you two line widths in one: use the broad flat face for wide strokes up to 15mm (ideal for bold lettering fills and backgrounds), or use the angled edge for narrower, more controlled lines. It’s the versatility of a brush with the consistency of a marker.
