Scientific American 13, 10.12.1853
A Frenchman has discovered a substitute for paint over plaster. A coat of oxide of zinc mixed with size, and made up like a wash, is first laid on the wall, ceiling or wainscot; and over that a coating of chloride of zinc, prepared in the same manner as the first wash, is applied. The oxide and chloride immediately effect a sort of combination, forming a cement, smooth and polished as glass, and possessing the advantage of oil paint without its disagreeable odor.
