pastel as underpainting for oil?

[Adriano Maggi]

I forgot the last one!

[Claudemir Bonfim]

Very interesting.

I only paint directly on the canvas.

What do you fix the pastel with to prevent it mixing with the paint?

[Adriano Maggi]

I usually use hair spray becouse it smells good ,but any fixative for charcoal will do.

I use hair spray to fix my charcoal drawings too, that is not as toxic as the other sprays, I use them for years and I never had trouble doing it. The point is, you cannot trust some brands.

Hi Claudemir
if you are seying that sometimes it doesn't work,then you just have to
touch the charcoal and try another brand.

Hello Adriano

You asked me to comment here, but I haven't got an answer for you regarding the technique of putting pastel under oil painting. The only thing that does concern me is how hairspray might react with the oil paint - what it might do to the painted surface after time. Perhaps you should do some research into more environmentally-friendly art fixatives that have been tested to use with oil paint. I am sure there's something out there.

Also, although I hate to stick my oar in, I am not sure why you would want to cover up a good, finished and satisfying pastel work with oil - why not just do an oil painting as well as the pastel.
