Atelier Interactive Slow Medium extends wet-in-wet blending time, increases translucency and improves acrylic flow. Ideal for glazing and other techniques which require thinner paint and longer working time. Atelier Interactive Slow Medium Thick is excellent for outdoor sketching but is not as popular for indoor painting.

Atelier Low Viscosity Retarder makes blending with, particularly wet-over-wet & wet-over dry, acrylic colours easier. Atelier Low Viscosity Retarder is an additive, so only a certain amount can be mixed before the mixture becomes unstable.
