LUKAS Drying Retarder (liquid form) slows the drying time of acrylic paints, extending their “open time” to allow for longer wet-on-wet painting techniques. The amount added influences the paint’s transparency – the more retarder used, the more transparent the colours become. Once dry, it forms a waterproof layer.

Acrylic paints typically dry very quickly, with thin layers setting in as little as five minutes and thicker layers drying overnight. For artists who want more time to blend or work wet-on-wet, drying retarders provide an effective solution to control this fast drying behaviour.

• Slows the drying time of acrylic paints
• Ideal for extended wet-on-wet techniques
• Keeps paint workable for longer periods
• Affects the viscosity and transparency of paint
• Dries to a waterproof finish
