Grumbacher is dedicated to making sure that the original paint attributes are not compromised, but enhanced through the use of painting mediums. These mediums thicken or thin without harming the color's adhesive, binding or film forming qualities. Myriad effects such as increased flow and rapid and slow drying of color may be achieved. The oils, resins and solvents in these mediums have been selected to guard against yellowing and cracking, and have proven themselves over many generations of use.
