All grease-free and somewhat absorbent surfaces can be used for painting with water mixable oil paint, provided they are prepared with a universal primer. Usually, stretched canvasses are already provided with this preparation. Untreated surfaces such as paper, cardboard, wood, cotton and linen, can be prepared with Gesso 1001 from Talens. This is an excellent universal primer on a pure acrylic basis. When preparing open woven canvas yourself, it is recommended to first apply a layer of Amsterdam acrylic binder. This seals the meshes of the canvas so that the Gesso does not come through at the back.
