Matisse Extender Medium

Matisse inks can be thinned with water adding to their versatility, however we recommend an addition of Matisse Ink Extender when water resistance is required as the thinning with plain water will lower the amount of acrylic binder present, weakening the ink's water resistance. Adding water alone will also increase the drying time. Up to 25% of Matisse Ink Extender can be added for thinning.
