Spray Chalk instantly turns to powder as it comes out of the can to let you create cool sidewalk chalk designs with a spray can effect. Its versatile formula goes where sidewalk chalk can't, including grass, asphalt, snow and concrete. Easy-to-clean design fades to a white color naturally in seven days and dissolves in the rain or with a hose for simple cleanup. Plus, its blendable colors can be layered together when wet to create fun, unique effects. Washable, nontoxic colorants allow you to safely color around vegetation and pets. Spray Chalk is perfect for turning outside surfaces into playing fields, games, signs or outdoor masterpieces.
