Isolation coat on acrylic paintings

Postby MiChelleAngella » Sun Nov 11, 2012 12:19 pm

Hi, I have yet another dilemma..
Usually I varnish my acrylic paintings when they're completed, and I always apply an isolation coat using soft gel gloss medium before I apply the varnish. [I never skip that process ever, because it serves as a protective layer between the painting and the varnish].
But this time I realize I didn't have enough soft gel medium [gloss]...
and I have to take the paintings to a gallery in two weeks...
[the art shop won't get the gloss medium until 3 weeks time.. they only have matte gel medium available]

My question is this:
Can I use a [matte] gel medium as an isolation coat as well?
[or is that a big no-no]

Another question is:
Must I take the chance and apply the varnish directly to the painting without any protective layer between?

EDIT: I made some tests on some smaller paintings and ruled out matte medium as an isolation coat, as well as varnishing directly on painting... that's definitely out for me..

Sorry, Michelle, I cannot be of any help as I have never varnished a painting. :?

I guess it's a matter that I live in a place with hot weather that can be hard on an acrylic painting, so to make sure it's protected from the heat and dust, I feel much better when I varnish it [as it becomes a seal] plus it brings back the vibrant colors as when the painting was wet.
Perhaps when I relocate to europe I might not need to varnish the paintings, but i'm sure I will still want to anyway. :)

I use a matte spray sealer that does the same thing. The sign I painted a couple of years (summers) ago is still doing great and it is outside unprotected from the weather. Summer before last we had temperatures of over 100 degrees F for 103 days in a row (a record) and we had freezes that winter. It is still holding up. (I thank God. :D )

I suppose it is really up to the artist, however. One cannot be too careful when it comes to their work. Whatever works, huh. :D

That's something I could look into.. [thanks for the suggestion]..
I've used Krylon spray on my graphite drawings and that's good stuff, but i've not had success with spraying paintings... would you recommend a matte spray that I could try? Thanks! :)

Michelle, I've used the Krylon matte sealer on most of my paintings. "Rust-oleum" also makes a matte spray sealer which seems to be the same to me.(just a little more expensive - may be more of an industrial grade, I'm not sure) That is what I used on the sign.(about 4 good coats) You might try that.

I hope that's of some help, Michelle. :D

Hey Michelle,

Don't know if this is too late to be of any help, but I also seal with acyrlic sprays. I have used both types, matte & gloss with great success. I like "Clear Coat" or use "Top Coat" (applied with an airbrush). The most important thing for me is to apply two thin coats with lots of dry time. I spray them laying flat so I don't have to worry about runs.

One of the advantages of using a different sealer base is that it's easier to remove just the finish if necessary (ie... acrylic water based as opposed to oil based varnish).

never too late :)
I like the idea of application with an airbrush.. i've never thought about that, and it's been a dream of mine that one of these days, i'd like to get an airbrush set..
Thanks for your suggestion Sharla :D
