Does Oil Paint Adhere Weakly to Oil Primers? Or is this a Case of the Blind Leading the Blind?
We often joke that much of the internet is filled with inaccurate information, but sometimes, the errors are overwhelmingly glaring, especially from websites offering paid instruction. Here is one example regarding preparing supports for oil painting. See if you can spot the errors.
In the middle of 19th century, when connection with Old Masters’ methods was completely lost, many misleading techniques of painting and priming methods occurred. Artists started to use Oil Based Primers, which caused significant damage to paintings and dramatically reduced the age of many works from that time. Most of the works painted over Oil Primer, adhere to the ground very weakly, and some paint is already falling off. The fact is, that the Oil Ground has a glossy surface that does not absorb oil from the paint, thus painting layers are very poorly attached to the oil ground, and after sufficient drying time, it can easily separate from it. The connection between the ground and a paint layer is unstable, especially in a multi-layered impasto painting.

Frequently Asked Questions (FAQs)
What do painters do to support canvas?
Painters typically prepare canvas supports by stretching them tightly over wooden frames. The canvas is secured with staples or tacks to the frame, ensuring a smooth and firm surface, crucial for stable painting application. In the traditional preparation for oil paintings, painters apply sizing to tighten the canvas further and prevent oil penetration. The sizing may consist of animal collagen glue (rabbit skin glue), polyvinyl acetate (PVA), or vinyl acetate-ethylene (VAE) dispersions. Artists may apply an acrylic dispersion primer for acrylic paintings, commonly sold as “acrylic gesso.”
What do you put on canvas before oil painting?
There are two standard methods for preparing canvas to receive oil painting. The first method is to size the canvas with an adhesive such as rabbit skin glue and then apply an oil ground. The second method Before beginning oil painting, a primer, commonly gesso, is applied to the canvas. The primer prepares the surface in both scenarios by providing a slightly textured layer that oil paint can adhere to more effectively. The ground stiffens flexible canvas supports, making it less responsive to environmental changes, such as humidity and temperature. It also protects the canvas fibers from the corrosive nature of oil paint, enhancing the longevity of the artwork.
How do you prepare a surface for oil painting?
To prepare a surface for oil painting, the artist first ensures it is clean and free from dust or grease. Then, a primer layer is applied to create a suitable texture for oil paint adherence. Additional sealing and priming steps may be necessary for surfaces like wood to prevent absorption and ensure a smooth painting surface.
