You would think that the answer would be an unqualified yes, but the name “liquid chalk markers” refers to the effect of these markers, not their composition.
Liquid chalk markers are designed to be used mainly on non-porous surfaces such as glass, metals, plastics, ceramics, and other materials that don’t permit the passage or air or water.
Old Style Chalkboards:
Chalkboards used to be made of sheets of slate, which is a porous material. If you used liquid chalk markers on these boards you would have a very frustrating experience when you tried to remove it.
The Modern World!
Luckily, most modern chalkboards are made of porcelain enamel, a non-porous material that is lighter in weight and lasts longer than traditional slate. It is easy to use liquid chalk markers on their surface and clean up is a breeze with just a damp cloth to wipe away the markings.
If you don’t know what your chalkboard is made of try rubbing it with a damp cloth. Slate and other porous materials will retain the moisture while a non-porous board will quickly dry. If you have a slate chalkboard or other porous material that you feel is the perfect surface to show off your chalk markers you can seal it with an inexpensive aerosol sealer available at craft stores.
