Initially, the single-colour coating composition contains a first dye, a thickener, a surfactant or a mixture of surfactants with hydrophilic-lipophilic balance (HLB) less than 9 or greater than 11 and binder. All components are dispersed or dissolved in an organic solvent and water.

Additional decorative effects are achieved by sliding the surface using a putty spittle or some other instrument while the coating composition is still in liquid or quasi-liquid state. The set for applying the decorative coating onto the surface contains the said composition and a label.
