NEVER use any chalk markers on chalkboard paint or low-quality porous chalkboards. Test in a corner first.. Use new upgraded ink that brings more vivid colors. Colors are vibrant, and long lasting!. Liquid chalk markers can be erased easily by wiping the area with a damp cloth or paper towel.(ERASABLE ON NON-POROUS SURFACE ONLY!). Always thoroughly shake your marker if you haven’t used it recently (with the cap on) to make sure the powder and liquid are well mixed. This ensures a smooth flow and bright colors. If it’s runny, shake a little more.
