Kaleidoscope School Board Black Paint is a matt black coating specially made for surfaces like chalkboards. It allows chalk writing to show up clearly and erases cleanly. The paint is highly resistant to abrasion and frequent erasing. It has a low gloss or “no glare” finish, so writing is easy to read under different light conditions. Because it’s durable and washable, it holds up well in classrooms and places where people use it often.
