AK Interactive 3Gen - Retarder

The bottles identified by labels with a grey circle comprise specially formulated mediums to modify the properties of paints.

AK Interactive Retarder is an additive used to slow down the natural drying time of acrylic paints. It extends the "open" (working) time of the paint, preventing it from drying too quickly so you can easily blend colours, create smooth gradients, and perform brushwork without rushing.

It comes in 18ml bottles.
