Grumbacher mediums thicken or thin paints without harming their adhesive, binding, or film-forming qualities, and allow artists to achieve increased flow and rapid or slow drying. Also proven to guard against yellowing and cracking.

ZEC Medium —

Accelerate the drying time of your painting with this clear and colorless colloidal oil painting medium. Grumbacher ZEC Medium maintains the consistency and hue of the colors and holds any desired texture. In normal applications, paintings dry to the touch in 4 to 6 hours. ZEC should be diluted with Pure Gum Spirits of Turpentine or Grumtine only. It is not compatible with petroleum solvents, paint thinners, or odorless paint thinners. Mixtures of ZEC in excess of 1:1 will result in a brittle, dry paint film.
