Hello, I have been working with 2 surfaces at the same time and exactly the same resin mix. When I poured resin on canvas (white canvas for painting) there where only few bubbles and after hot gun they where gone, but when I poured resin over wooden board (cutting board for fruits) and went over with hot gun – bubbles would pop but even more came up to surface! It would not stop happening… Is it the varnish on surface of the wooden board or the fact that it’s wood? Or is it because wood got too warm? Its so confusing how the same resin worked out different on different surface 🙁 Any suggestions? Please help!
