An aqueous, reversible and storable coating for protecting spray cabins from enamal overspray consists of a mixture containing 5 to 80 wt. % of a C8 carboxylic acid and/or the alkali metal salt of a C8 carboxylic acid, 1 to 40 wt. % of a pH regulator consisting of alkanol amines and/or alkali metal hydroxydes, 1 to 15 wt. % of a laminar silicate and/or polyacrylate and/or carboxymethylcellulose, the remainder being water. The mixture may also contain ordinary additives, and has a pH between 6 and 10 and a viscosity of 30 to 50 DIN.sec. The invention also relates to a process for producing these coatings.
