Rain activated art uses special hydrophobic paint that only appears when wet.
Benefits & Problems Addressed
Take advantage of rainy days: Activates the streetscape during the rain.
Inexpensive use of unadorned space: Sidewalks offer accessible, unused space for fun, inspiration and art.
Tips & Techniques
Getting Started: See if there are prohibitions and graffiti laws that might be triggered. In general, paint that is temporary & non-damaging and messages that are not advertise are legal. With rain-activated paint, there are only 2 colors (wet & dry gray). Avoid dirty, sealed, non-concrete sidewalks that drain poorly.
Art ideas: For spray on, make stencils of sayings, hopscotch, and games.
Stormwater messages: Use in runoff prevention campaigns to help pedestrians make connections between rain and pollution prevention.
Where to purchase: Rainworks sells temporary paint in a starter kit and full bottle. Google hydrophobic paint (make sure it is non-toxic, non-corrosive and temporary).
