Most of my work these days is a mixture of oil pastels and acrylic paint. These two mediums don’t mix well together, but still can be used in the same painting.
When using oil pastels, it’s the same basic rule as using acrylic & oil paint together. As long as the acrylic paint is underneath the oil pastels or in an area alongside the oil pastels, it’s fine.

You shouldn’t paint with acrylics over oils because the paint will crack as it dries. Same rule applies for oil pastels & acrylic paint. I’m not sure if oil pastels crack, but they are water resistant, which means acrylic paint won’t stick or dry if painted on top of the pastels.

Oil pastels are slightly different than oil paints because they never dry fully. It’s more like the pastels set & firm up a bit over time. Varnishing them helps give the painting a protective coating, but oil pastel paintings can be scratched if not taken care of properly.
I leave my paintings on my drying shelves to air out for a few days before I varnish them. If you try to varnish too soon the oil pastels will smear. I didn’t know this when I first started using varnish instead of fixative spray. I tried to varnish a painting right after I was finished creating it. The oil pastels didn’t have time to set, and I smeared one of my portraits a lovely shade of orange. Oops!! Lesson learned.
The varnish I use is Liquitex. Clear gesso also works well, also, and gives the surface a grungy, gritty feel, which I love. I’ve been using it in my work for years.
I don’t recommend using the clear gesso between layers of oil pastels, like you can with acrylic paint. If you use clear gesso on acrylic paint, it sets those layers, and you can easily paint more on top. Doesn’t work the same with oil pastels. I’ve tried to go back in and fix little areas, but once an oil pastel painting has clear gesso on it, it doesn’t accept new layers easily. So make sure your oil pastel painting is completed before using clear gesso on it.
Thanks for stopping by. I hope you have a lovely creative day.
