Black Chalkboard Surface
Deep black, made to be looked at.
A high-opacity black lacquer for boards where contrast is the product — cafe menus, studio walls, wayfinding, photo sets. Dense pigment keeps the surface reading black rather than dark grey, even after a year of daily cleaning.
Coating build
Primer + black top coat
Total DFT
22 – 24 µm
Writing medium
Chalk & liquid chalk
Why buyers specify it
Built for rooms where the board is the sign.
01
Opacity that survives cleaning
Pigment loading is set for commercial cleaning cycles, so the surface stays dense black instead of fading toward charcoal.
02
Even sheen under shop lighting
Matte level is controlled across the whole coil — no patchy reflections running down a wall of menu boards.
03
Two mediums, one surface
Takes stick chalk and liquid-chalk markers, and wipes back to full black with a damp cloth.
04
Same tolerances as the range
Produced on the same line as our green and whiteboard surfaces, with the same flatness and width control.
