Test Surface for Erasability
Before using Crafty Croc Liquid Chalk Markers, we highly recommend you test the surface you are planning to write on if you are unsure of its erasability.
To test, follow these easy steps:
- Find an inconspicuous area on the surface to test your markers.
- Place a small dot or line on the surface.
- Repeat with all colors. It pays to test all colors as some may leave more obvious shadowing than others depending on the color of your surface.
- IMPORTANT: Wait 24-48 hours. Patience is required! This is important as shadowing is caused by the surface absorbing the liquid over time. It may wipe off with no issues if left for just an hour but leave shadows after sitting for a day.
