In various embodiments novel coatings for the protection of a paint booth are provided. In certain embodiments the coatings comprise a maltodextrin, a humectant; and pH adjuster. In certain embodiments the coatings can optionally additionally comprise a thickener, and/or a defoamer, and/or a surfactant and/or one or more preservatives. In certain embodiments the coating is a clear coating comprising a maltodextrin, a thickener (e.g., an xanthan gum thickener), a defoamer (e.g., a silicone defoamer), a surfactant (e.g., a nonionic surfactant such as an ethoxylated alcohol surfactant), a humectant (e.g., glycerine), a pH adjuster/humectant (e.g., triethanolamine), and one or more preservatives (e.g., of a combination of as 5-chloro-2-methyl-4-isothiazolin-3-one and 2-methyl-4-isothiazolin-4-one (KATHON LX®), an aqueous dipropylene glycol solution of 1,2-benzisothiazolin-3-one (PROXEL GXL®), potassium metabisulfite, etc.). 1.
