Need help with oil painting on masonite
CGreen3331
I have not had much experience with oil painting on masonite. I have read
a couple of books on this topic but they have conflicting methods. Is it
true that I will need to coat the board with glue sizing before and after
the coatings of acrylic gesso primer to keep it from rotting from the oil
paint?
I have already applied the gesso primer to the board without the glue
sizing but I have not started painting yet. Is there any way to save the
board at this stage if the glue sizing is needed?
Please give me your opinions on this matter.
Thanks,
Patricia

not a painting group. I guess you are one of those who don't
think that photography is an art. Go away.

Sorry about this message being posted to the wrong group. Although I am
not sure how you interpreted my question (for help not rude remarks) as a
'I guess you are one of those who don't think that photography is an art.
Go away.' derogatory slam against photography. So I would like to
apologize to you, Morton. I never meant to hurt your frail ego.
And I would like to apologize to the rest of the group for my posting of
this second message which has nothing to do with (as Morton so mannerly
pointed out) the group's charter. I just get angry when people act that
way (it usually means they are hiding the fact that they don't know
anything).

You don't need to seal a masonite panel if you use acrylic gesso--just be
sure and paint edges and back. Use glue sizing only if you use an oil
priming or real gesso (chalk, gypsum, hide glue--mainly for egg tempera
nowadays).
Be sure your masonite is UNTEMPERED! Tempered masonite uses impregnated
resins to make it waterproof for outdoor use and gesso will eventually
peel off with age (and your painting!). You can tell by an old trick a
lumberyard salesman showed me: if you can dig your fingernail into the
fibers at one corner, then it's untempered. If you can't make a dent, it's
tempered!
In the future, be sure and rough up the surface of the untempered masonite
with medium sandpaper (80-120) so the acrylic gesso has something to hang
on to.
By the way, there are conflicting opinions among museum conservators about
painting oils over acrylic gesso. Some say only use oil priming.
Personally, I have oil paintings from 20 years ago painted on acrylic
gesso on masonite and they look terrific. So, take your choice!
The above is as good advice as you'll get--but be warned: everybody has an
opinion!!
