Hi

I've been using Glass Cast 50 for a couple of projects and  I seem to get lots of air bubbles in the set resin. It looks great when poured.
I mixed by weight, clean mixing cups, stirred for 4 minutes and used a heat gun to remove surface bubbles. The room was kept at 20c
The picture is a side view of the layer.
Any ideas what I'm doing wrong?




bubbles.

Hi

I had heaters running in the room and the thermometer was saying 20c. The resin was poured as a second layer so the majority of the resin was well away from the wooden sides.

The first pour was done a week ago and I lightly sanded the surface  and cleaned with paper towels  before this pour.

Thanks
