Sealer over acrylic painting on canvas.

What type of sealer is best to use over acrylic painting on canvas? I have tried many different things and some dry tacky and some will seem dry but will stick to other paintings if stacked next to each other and some show circles from bubble wrap when mailed. I have asthma and am trying to get away from using the spray acrylic sealers because of the fumes. Do you have any idea of a good product to try? Thank you in advance.

Varnishing an Acrylic Painting

Acrylics will stick to acrylics and any plastics. So yes, the bubble wrap would definitely leave impressions. You'll need to isolate the canvas in a paper wrapper before adding the bubble wrap.

When I stack my painting against each other, I use cardboard between them.

I use brush on acrylic polymer varnish for my canvas work. Look for a varnish that will remain flexible such as Liquitex Acrylic Polymer Varnish (water-based). Do not use varnishes meant for rigid surfaces.

I think you'll enjoy working with this varnish.
