Can acrylic paint be applied to a linen support? I know that many artists do paint with acrylic on linen ...but that doesn't mean it's technically correct. I like the texture of linen and would like to use acrylic paint on linen. However, I have read that the "oily" content of linen makes it less ideal than cotton canvas for acrylic paint ...causing the paint to come off of the support over time. Is this true ?
I just looked at some older test paintings on linen, and did not see any signs of delamination of the acrylic products.

The acrylic gesso should be thin enough to absorb into the support and surround the fibers. If the acrylics do not do this, they will delaminate, even off of cotton duck canvas.

You raise a valid question when referring to the lignins in the linen. I think these do prevent the kind of complete absorption into the fibers as you see with cotton canvas. However, we don't see any evidence it is enough to allow for later delamination, but again, if the acrylic gesso or other priming coats are not thin enough or put on in the correct manner, there may be cause for concern.

Our common recommendation is to first size the support with GAC 100, one of our specialty polymer mediums. Apply two coats of this, followed by 2 or more coats of Gesso.
