| Protective coating for surfaces coated with flat paint; it also can be used on wallpapers made with colors that do not smear when wet; the coating is made by soaking ordinary laundry starch in a small quantity of cold water to break up lumps; boiled water is then poured on to cook the starch and make it transparent; mix to consistency of cream, let cool, and apply with large paint or calcimine brush; coating should be stippled while still wet to remove brush marks; it may be removed later by using water and sponge.
