How important is canvas absorbency in Alla-Prima painting? I don’t find many painting tutorials(books/internet) discuss about the absorbency of the canvas. but while actually painting, I find that absorbency affects a few things. I used to paint over a self-prepared canvas where, i used to prime a cloth with ‘glue+plaster of Paris’. This used to be a pretty absorbent surface. it lacked the ‘luminosity/slickness’ but I could clearly paint over it with another layer of paint with minimal disturbance to the underlying paint layer(particularly when the underlying layer is very thin and still wet). This gave a lot of flexibility on the over painting(not archival at all!).
Recently i started using proper ready-primed canvas. i think ready primed surface has a reasonable absorbency that was helpful in over-painting. But i disliked the canvas texture, so i decided to add another coat of acrylic gesso to add some texture. But it seems to get too slick to paint over acrylic gesso. after a laying in a turpentine wash, i can cleanly swipe it off and get a white ground again(barely noticeable stain remains), it is that slick. it seems to feel a bit rubbery. In some books I read that lead priming(though toxic) is the best surface to paint on. In some of the photos of lead primed canvas, I can see them to be slightly porous – I assume its slightly more absorbent. I could be wrong here. I have never used lead priming.
I can see in some video tutorials, painters over-painting with ease over the thinner underlying layer with minimum disturbance.
I am really confused whether the issue is with my technique or with the canvas absorbency. I need some guidance here. Should the canvas be that slick and should I look at my painting technique rather than the surface? Is there any other gesso-like primer that will solve the absorbency problem?
