Slow Dry Medium 250ml
Holcroft Slow Dry Medium is used to add to acrylics to slow down the drying time and increase the open time of acrylic paints. Particularly useful when painting wet-over-wet over dry techniques. Makes blending acrylics easier. As this medium does not contain a binder; only a certain amount of additive can be mixed with the acrylic paint before is becomes unstable. Do not add excessive medium or the paint will not cure.
Recommended volume is no more than 10%.
Shake bottle gently before use. Clean up with soap and water.
