If you’re like me, you’d most likely buy a quart of flat Behr paint from Home Depot for about $13. If you buy a $10 container of BB Frosch chalk powder, that quart would cost about $23 to mix yourself, much less than the $34.99.

Chalk, a sedimentary rock, is a soft form of limestone that is not well cemented and thus is often powdery and brittle.
