I recently finished up my sister-in-law's Charlotte Skyline acrylic painting with an isolation layer and two layers of varnish, to help protect the three large canvases while they are shipped to her and on display in her apartment for years to come.
Because I had never done this step to an acrylic painting before, having only minimal experience with acrylic and using only making small paintings (or ones not even on canvas, but just on acrylic paper), I first had to buy the supplies.
I bought a new flat brush, Golden polymer varnish, and Golden soft gel gloss. (I also bought Golden soft gel matte, thinking I could use that as an isolation layer - only to later read on the label "DO NOT USE AS AN ISOLATION LAYER," at which time I went out and bought the soft gel gloss as a replacement.)
I used the Golden brand website to find instructions for how to apply the isolation layer and varnish layer. The directions were also on the labels.
I applied an isolation layer to my "test painting" first - "Find a Proverbial Mountain," the much smaller acrylic painting I completed in November 2016. I let that dry for a couple days, and then added a layer of varnish on top. When that painting survived just fine with no ill effects, I decided I was ready to try tackling the large skyline triptych.
I followed the same procedure on the larger painting, following the directions on the label for ratio of soft gel gloss to water, and applying it in a thin isolation layer. It was white at first, but dried clear.
After I'd given that a couple days to dry, I went in with the polymer varnish (also diluted with water according to the label instructions). I did one coat to all three paintings, let it dry for 24 hours, and then added a second thin coat on top.
I then let it sit on my table for two weeks to make sure it was all fully dried and cured. I knew I would have to wrap the canvases in plastic and bubble wrap (not to mention packaging them in cardboard boxes) in order to ship them to North Carolina, so I wanted to make sure they were completely dry and ready before I did any of that.
They turned out great! And now I have the supplies on hand to do the same steps to any future acrylic paintings as well, to make sure they're all protected and will last a long time.
