The drying retarder College is a pasty additive that delays the drying time of acrylic paints and gels and thus ensures longer workability (especially in the wet-on-wet painting technique). With an addition of about 20% drying retarder, the drying time of the acrylic paints increases by about 50%. The Retarder College must not be used pure (maximum addition: 30%)!
