2024年1月5日 · Even though it seems counter-intuitive to put a gloss isolation coat down first then put another matte varnish coat on top. If you left it without the isolation coat the matting agent in the varnish would remain on the surface, the solvent would be absorbed into the ground resulting in a white residue.

2022年2月22日 · An isolation coat is a final coating of medium before you apply the removable varnish layer. This protects the paint layers from abrasion when your removable layer is removed. Also, when it comes to isolation coats, never use anything other than gloss medium. Gloss medium is the clearest and allows more light through.

2012年8月27日 · I was prepared to apply the varnish right onto the acrylic painting, but then did some research and found some people apply a protective "isolation coat" of Golden Soft Gel Gloss, which permanently seals the painting, allowing you to then apply a removable varnish, which can be removed in the future if necessary without damaging the painting ...

2021年1月14日 · An isolation coat is just a non-removable layer that acts as a barrier between the painting and the final varnish. It can be something that you might not normally use as a finishing varnish, but it can just as easily be a different sort of varnish than …

2023年11月16日 · I've been painting in acrylics for years... but only recently started making artworks for displaying too... I have sort of educated myself on varnishing paintings (on canvas and on paper)... but I use an Acrylic varnish (doesn't exactly specify on it what kind), but it is water-based and I found that you can remove is from the painting using water.

2024年3月4日 · One from last year that I directly applied Liquidex Professional Gloss Varnish onto the painting and another that I just completed. I was looking online for what brush to properly apply varnish with (I used a sponge brush last time lol) and they mentioned using an isolation coat in between the painting and the varnish to protect the paint.

Usual process is - painting, isolation coat (often some acrylic medium, yes) and then varnish which is of different chemical composition, like solvent based. Then during removal, solvent will be used to remove varnish, and isolation coat will protect the underlying painting from any chemical reactions or scrubbing.

2023年11月6日 · Well, the fact that it's an acrylic painting and that it doesn't have an isolation coat complicates things. If you're talking about, like, an absolute best practices next step, it'd be to do another layer with a different varnish than the Gamvar, one that uses a different solvent. That'd make the Gamvar layer the isolation coat, effectively ...

2023年2月1日 · I recommend using an isolation coat before varnishing- if you don’t like how the varnish looks or the application didn’t go well, you can remove the varnish without harming the painting. I recommend an isolation coat before varnishing on all works that will be displayed for decades to come. Art restorers can easily remove and replace old ...
