Understanding the Basics: Acrylic and Oil Paints
Before diving into the question of painting oil over acrylic, it is important to understand the basic properties of both acrylic and oil paints. Acrylic paints are water-based mediums that dry quickly and can be easily cleaned up with soap and water. They are often praised for their flexibility and resistance to cracking. On the other hand, oil paints are oil-based, take longer to dry, and require solvents for cleanup. They provide richer, more vibrant colours and better blending capabilities. Both types of paints have their unique charm and offer different benefits to the artist.
The Science Behind Painting Oil Over Acrylic
There is a fundamental rule in painting known as 'fat over lean', which means that each subsequent layer of paint should contain more oil (fat) than the layer below. This is to ensure proper drying and to prevent cracking. Since acrylic paint is water-based (lean), it is technically feasible to paint oil (fat) over it. However, the underlying acrylic layer must be completely dry before proceeding, as the oil paint layer will restrict the drying of the acrylic layer, leading to potential cracking or peeling.
Practical Tips: Oil Over Acrylic Techniques
If you decide to paint oil over acrylic, there are some practical tips to keep in mind. Start with a thin layer of oil paint, gradually building up the thickness. Avoid using heavy, thick layers of oil paint over acrylic, as this can cause the paint to crack as it dries. Also, remember to wait until the acrylic layer is completely dry before applying oil. This could take anywhere from a few hours to a few days, depending on the thickness of the acrylic layer.
