Slow-drying extender for acrylic colours. 100% acrylic medium that increases translucency and working time for blending and glazing acrylic paints. Use alone or blend with acrylics in any ratio. Useful for wet-in-wet blending. Improves brush-ability. Working time depends on surface absorbency and environmental conditions. Do not apply thickly. Dry completely before re-coating to avoid lifting. Do not use as a varnish. Always test for your application. Apply above 49F/9C. Clean with soap and water.
