Oil painting on paper:
Is a thing.
1. Tape/staple/pin down
2. Seal w/ diluted acrylic.
- I’m thinking 2 coats golden gloss and 1 or 2 coats normal primer for the tooth. You don’t want the oil to absorb into the paper much if at all.
- or 2 coats prime and seal if the stuff is flex enough. Try both.
Been using Behr premium (100% acrylic) flat white tint base as a gesso, since it’s a one coat primer-paint and flat is absorbent similar to purpose made gesso. Is great for reusing canvases. Coveres them right up. Worried it might not be enough tooth for oil though, or it might peel off if oil is absorbed beneath the primer layer. We’ll see I guess.
Oil over acrylic vs acrylic over oil:
Oil is rigid, acrylic is flexible.
If the acrylic moves under the oil, it will crack.
Acrylic can in fact be put over cured oil. It’s the gloss of the oil that may make it delaminate, not any chemical incompatibility. Sticky primers exist for this purpose, and they come in both alkyd/oil and acrylic versions.
But oil is also removable with solvents while acrylic isn’t, so there is that.
Cured oil paintings are not greasy but are glossy.
Oil paint substrate bond is purely mechanical.
Cured acrylic is porous but is also an excellent glue.
= oil over solidly bonded Behr housepaint used as gesso should not be a problem. We will see.
= acrylic painting over an oil painting whited out with oil based sticky primer should be fine too.
probably my most representative piece for some time. tends to become deadlier when exposed to sunlight.
