Grumbacher - Acrylic Retarder

Acrylic Retarder

Blend acrylics like oils with extended open time for seamless transitions

Acrylic paint's rapid drying time solves storage problems but creates blending challenges. This retarder extends your working window without compromising paint body or color intensity. The full-bodied, colorless medium integrates completely into acrylic colors, slowing surface skinning while maintaining proper flow characteristics for brushwork.

Mix small amounts directly into paint on your palette, a little goes surprisingly far. The medium proves particularly valuable for atmospheric gradients, portrait work, and any technique requiring extended wet manipulation. Colors remain workable long enough for genuine blending rather than rapid layering that mimics the effect.

Grumbacher formulates this retarder to extend drying time predictably across their color range without leaving the tacky, unstable surface that excessive water creates. You maintain control over paint consistency while gaining the time techniques like scumbling and soft edges actually require. Particularly useful in warm, dry studios where standard acrylics can set up before you've finished a stroke.
