Abstract
The present invention provides a method and kit for the treatment of surfaces, such as the skin surface of a user, to impart hydrophobic characteristics upon the surface. The treatment of surfaces to impart hydrophobicity protects equipment, personnel, and animals from the effects of aqueous solutions such as water, toxic slurries, concrete, acids and bases.
