Water-mixable oil paint

Mediums for water mixable oil paint affect the properties of paint and are often indispensable for the long-lasting construction of your painting. Varnishes are important to seal and protect your painting. Discover our range of water mixable oil paint auxiliaries.

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.

Technically-speaking the difference lies in the binder. With alkyd paints this is an alkyd resin dissolved in white spirit. With Cobra water mixable oil colours this binder consists of drying oils.

Its use results in the following differences:

• Alkyd paint dries considerably faster than Cobra water mixable oil colours, as a result of which there is less time to work wet-on-wet.
• Solvents are necessary for alkyd paint in order to thin the paint and clean the equipment.
• For Cobra water mixable oil colours no volatile solvents are necessary. Water can simply be used.
• With the use of pure alkyd paint, the brush stroke is more flowing.
  

When using pure Cobra water mixable oil colours the brush stroke remains 100% during drying.

What brushes you need for water mixable oil colours depends on the technique applied and your personal preference.
