Does anyone have recommendations for some chalk that resists water very well?
I’d love any recommendations of brands, specific chemicals or properties to look for, or maybe questions that I would need to answer about the environment.
I’m planning to use my chalk on my asphalt driveway.
Krylon makes “marking spray chalk” that is temporary and takes anywhere from a few days to a couple weeks to fade. It’s what we used to paint the train tracks on our parking lot for a kiddie train at our fall festival event.
