The bumps are from the paint, I believe. I am almost positive they aren't bubbles, because they first showed up after the pour, but they weren't popping like the rest of the bubbles with the blow torch/straw method. I even tried to go in with a toothpick while it was still wet, and scratch out the bumps, but to no avail. Incidentally, the toothpick worked great for picking out stray cat hairs. (I love the boy, but his hair ends up everywhere, even though he was banned from the room for the last few days, and I lint rolled furiously before going in for the pour). Anyhow, the paint was sponged on, so it was a bit uneven to begin with... before adding Envirotex, I sanded it a little by hand, but I am guessing not enough. Sigh. I will see what some hand sanding can do to the Envirotex... so you think I need to flatten those bumps completely before repour?
