Crayola Sidewalk Chalk is a molded chalk made of Plaster of Paris and color pigments. Although it is designed to be used on sidewalks and driveways, the chalk contains colorants, which may stain clothing and other household surfaces. If the chalk is used on a newly poured sidewalk or driveway, there is a possibility that the open surface pores in the concrete could absorb the colors.

We suggest testing the Crayola Sidewalk Chalk in an inconspicuous area and then try washing it away with water. In most cases, the chalk markings wash away with the first rainfall if it is used on a paved or poured surface that is more than two years old.

Crayola offers stain removal suggestions as a service to consumers. You can find this information by going to http://www.crayola.com/canwehelp/staintips/stain.cfm.

Please bear in mind, all the stain removal suggestions we offer have been tested in our laboratory but we are unable to guarantee the results. We recommend you test our suggestion in an inconspicuous area first.

Crayola® manufactures two types of chalk, extruded and molded.

Extruded chalk, such as Crayola Anti-Dust® White Chalk, primarily contains calcium carbonate. Molded chalk, such as Crayola Children's Chalk (available in white or colored), is a softer chalk, and is not dustless.  This type of chalk is recommended for children's chalkboards as well as construction paper, cardboard boxes and paper bags. 

Crayola Sidewalk Chalk is a molded chalk that is not intended for use on chalkboard surfaces. It does not include calcium carbonate. This product contains plaster of paris which has a gritty texture and may scratch your chalkboard.

The wife of the founder of our company, Alice (Stead) Binney, coined the name CRAYOLA Crayons. The name comes from "craie", the French word for chalk, and "ola" from oleaginous. This has been our trademark name since 1903 when our company was founded and remains one of the most important pieces of our heritage. The first box of Crayola Crayons was produced in 1903 as an 8 count box. It sold for a nickel and contained the colors red, orange, yellow, green, blue, violet, brown and black.
