Water-mixable oil paint

All surfaces that are free of grease and are somewhat absorbent, such as paper, cardboard, cotton, linen and wood, can be prepared with Gesso. With an open woven canvas, it is recommended to apply a layer of Amsterdam acrylic binder first. This seals the meshes of the canvas so that the Gesso does not come through at the back.

Yes, the oxygen absorption and thus the ageing process is slowed down by a final varnish. At the same time, the final gloss level is determined and the paint is protected against atmospheric contamination. Cobra water-thinnable oil paint dries like traditional oil paint through the absorption of oxygen, a chemical process. After the paint is completely dry, this oxidation process will not stop and an ageing process takes effect. Eventually, this can become visible as crackling. After the paint is completely dry (with normal layer thickness about one year, with very thin layers several months earlier, with thicker layers several years) it is therefore advisable to apply a final varnish. Oxygen absorption, and thus the ageing process, is slowed down by the varnish layer.

This is not recommended. The surface of both products is too closed, so that the oil can hardly or not at all anchor itself in the acrylic film. The adhesion of the oil film will not be sufficient.

Traditional oil colours and Cobra can be combined to a maximum ratio of 1/5 (i.e. up to 20% of traditional oil colours). Up to a ratio of 1/5: oil 1/Cobra 5.
