Oil Paint
Grounds / Priming
Hi,
i see some manufacture selling non-absorbent acrylic gesso for oil painting, the idea behind it is to overcome sink in with regular absorbent acrylic gesso. it maybe good for direct painting style, however i have few questions:
1, the adhesion between oil and acrylic is mechanical interlocking mechanism, if acrylic sucks oil into them, it means the surface area for adhesion is increase like 3D compared with if acrylic not absorb oil that adhesion is only at surface like 2D. so does this mean the adhesion of non-absorbent acrylic gesso is weaker?
2, with absorbent gesso, if painting in layer, because it sucks oil into ground, it systematically fat over lean as the lower layer gives oil so it becomes leaner once applied. however if it is not absorbent, then the layer will not gives its oil, so it may becomes more critical to judge oil content of each tube? which is very difficult.
hope to see your comments!
