Chalkola Liquid Chalk Markers can be used on practically any medium, but if you want to erase your art easily, you should use a non-porous surface. The term non-porous means that any kind of liquid and air cannot penetrate the material, and they just remain on the surface.
Here are some examples of non-porous surfaces:
- Sealed tiles
- Varnished wood
Make sure to always test your marker on a small area of the surface first, as sometimes it can be quite tricky to determine a porous surface from a non-porous one. For example, wood is porous but if it’s been varnished or covered with polyurethane it becomes non-porous. If in doubt, check first if water will roll off the surface without it sinking in. If it does, then it’s a good medium for liquid chalk markers. You can also learn: How to Remove Liquid Chalk Marker from a Porous Surface
