I watched Mark’s “oiling video” but it does not address a problem I ran into and I was hoping one of you guys might be able to help.
I finished a workshop painting recently on a MDF panel coated with a few layers of acrylic gesso then painted using Graham walnut oil based paints that someone asked if they could have for their home.
There were no solvents used at all, some linseed oil used to adjust the paint consistency.
Before giving it to them, I thought I would put a thin layer of linseed oil on it to bring some of the matte areas back to life (it had dried for about three weeks). I did this before with good results, however, this time it worked as usual on 4/5 ths of the painting, but on the bottom 2 inches of the painting the oil beaded up like water. I ended up having to sponge it off the next day with a cotton rag so it didn’t dry that way. I don’t know what caused this.
Is it a problem, which would prevent me from giving the painting to a friend?
I could paint another but they really liked this one, and as this is more of a quick (2 hours about study) not an attempt at accurate realism, the next one would be probably be noticeably different.
