ABSTRACT OF THE DISCLOSURE Spray booth walls and like surfaces subject to accumu- lations of waste solids can be protected by a subsequently removable barrier layer coating deposited from an aqueous solution of one water soluble copolymers of: (A) from 15% to 90% by weight (calculated with ref- erence to the copolymer) of at least one nitrogen-free ole- finic monomer, and (B) from 85% to 10% by weight (calculated with ref- erence to the copolymer) of at least one linearly polymer- izable monomer containing at least one tertiary amine func- tion. The copolymers preferably are at least partially neu- tralized with acid and/or quaternized, so that the pH of the total composition is not greater than 7.
