Alla Prima oil painting

I am an Alla Prima painter and i was wondering what medium mixture you used to tone/seal the canvas in your demo, and what suggestions you would have to get the best results.



Answer:
Hi Sam!

In the example within the site, Painting in oils Alla Prima I didn't use a toned canvas, though I mention it. The canvas, being store bought is already sealed with an acrylic gesso. You can use an acrylic underpainting (toning) of the canvas before starting in oils. It serves the purpose of toning and sealing. It can help push a predominant color in your composition.

Most gesso today on store bought canvas is an acrylic product, which serves a dual purpose. It penetrates the canvas fibers and seals it to prevent the oils in oil paints from contacting them. (They would rot otherwise) And secondly, to provide a smoother surface to paint from. In the example, I added an additional 2 coats to get my egg shell smooth finish using the process discussed both in the e-book, and the site.

I hope this helps!
