The Tools of your Trade: Acrylic Retarder or Slow Drying Medium

  • Acrylic Retarder is a clear, liquid medium that is used to extend the drying time of acrylic paint. (slow down the drying time)
  • It prevents the water from being absorbed into the atmosphere and drying out too quickly.
  • Its works great for getting an ‘oil-like’ finish to your blending.
  • Added straight to the paint, it can be used to mix colours on the canvas surface, as well as creating smooth blending effects.
