Everything to Know about Working Outdoors with Water Mixable Oils
Oil paints have long been used for their many unique properties like their extended working time and beautiful brush strokes. Although, working with solvents can be hazardous without proper ventilation and clean up takes longer than acrylic and watercolour. With water mixable oil paints, you are able to get the best of both! Easy, cleaning, and working solvent-free, all whilst still getting all the benefits of oil paints. These oil paints still contain oil and are a true oil paint but feature an additive that allows it to be mixed with water. That’s what makes, water mixable oils, like those from Cobra perfect for plein air. They offer benefits for your health and easy clean up. Plus, without solvent – it’s one less thing to pack for painting on the go!
