Abstract
A sprayable composition and a method of protecting material with the composition is disclosed. The composition comprises a polymer such as hydroxyethyl cellulose, clay, and water to provide a cover layer which, after spraying, is tough, flexible and water-repellent. Other materials such as shredded paper and gypsum can be used in the cover layer. The composition is effective as a cover layer over material such as soil, refuse at a dump site, or grain in a stockpile.
