A transparent extender to mix with Jo Sonja's Artists' Colors to achieve ragging, marbling and graining effects. May also be used as a painting medium to add translucency and slight texture to decorative painting details. "Kleister" is a folk art term for producing faux finish techniques. Kleister medium gives more body to paint and extends the drying time, and you can mix with Jo Sonja's texture paste in a one-to-one ratio to increase the textural properties.
