A significant body of research in conservation science, and more than 40 years of actual use, has repeatedly proven that high quality acrylic gesso provides excellent adhesion for oil paints and can be considered a fully archival and suitable ground for oil painters to work on. Golden makes several grounds that are appropriate for this purpose, including:
Evidence suggests that adhesion is rarely the issue when using oils over a wide range of acrylic products, and most oil paints should adhere well to the majority of our gels, paints, and mediums. Almost all acrylic paint films, regardless of sheen, are still porous enough to allow oils to penetrate sufficiently and form a reasonably strong bond. The real concern with oils is their tendency to crack as they become increasingly brittle and inflexible with age. This is true regardless of whether the oils are on top of acrylics or more traditional materials. Because of this, we do not recommend using oils over a very thick application or texture, of any material, without some concern. The reason is that these materials will likely change over time, as well as expand and contract in response to the environment, at a different rate then the more fragile oils can accommodate. Ultimately it is these factors, rather than the use of acrylics per se, that leads to the potential of cracking.
To lessen these risks, while also maximizing adhesion, we strongly recommend the following
