Making gradients with Amsterdam Acrylic Retarder and Slow Drying Medium

Use Amsterdam Retarder 070 to maximise the time the paint is wet. Without compromising on the quality of your paint. If you use a maximum of 5% retarder in your acrylic paint, the consistency of your paint will be the same.

If you want your paint to dry even slower, use Amsterdam Slow Drying Medium 071. You can add as much of this medium as you wish. But, the more you use, the more transparent your paint becomes. This can of course also be an effect you like.
