Thanks to Trish Grantham encouraging me when she visited recently, and finally having a well ventilated studio to work in, I used Envirotex Lite for the first time the other evening. It's a thick glossy resin coat that's traditionally used for bar tops. I believe it's also used for creating fake water in architectural models.
I mixed the two gloopy solutions provided and whipped them together with gusto, as the directions said. Then I poured the resin in a coil shape on the surface of two paintings on wood. Eric and I filled in gaps and made sure it got to the edges with a couple of stiff business cards.
Then came the most magical bit. The wet surface was a mass of tiny bubbles because of the mixing action, and the way to get rid of these was exhaling on the resin; the carbon dioxide dissolves the bubbles, leaving a surface as clear and smooth as glass. You can also sweep the bubbles with a propane torch flame to dissolve. Trish said that's what she does, and I can see how exhaling inch by inch from a couple of inches away might be a challenge with her large pieces - not to mention toxic.
We put them under a jerry-rigged tent to protect from dust. I can't wait to see how they turn out.
