I’ve been having a great time experimenting with resin coatings for my ink and acrylic work. I started with birch boards as a base, which is recommended, but I’ve had success with both board and tightly stretched canvas.
What I love is the way it makes colors pop! It certainly adds to the production of a piece in terms of time and technique, but it’s worth it. I use ArtResin, which is odorless and easy to mix up, though you DO have to heed the directions and wear shoes and gloves (sigh). I use a heat gun rather than a gas torch to run over the surface to remove bubbles, and seems to work. I’ve also had bad experiences using blue painter’s tape on the sides, to keep small droplets from forming and hardening. Instead I go over the drips with gloved hands to get rid of them, then sand off the dried remainder with a circular sander.
I still a,ternate between work with resin and paintings on raw canvas- tension between warmth that draws you in and a cool barrier through which to view the piece.
