DecoArt One Step 59ml DS69-3 crackle medium is a water-based medium designed to create aging effects with cracks and fissures on painted surfaces in a single pass. Applied over dry acrylic base paint, it produces visible cracks in 2 to 4 hours as it dries, and can be further enhanced with waxes or patinas. The product cleans easily from brushes with soap and water before drying. It is the indispensable finishing product for restoration projects of vintage furniture and decorative pieces.
