You can prevent this scenario as well as creating a smoother surface for painting (oil , acrylic – not so much for watercolor lol) by creating a thin undercoat of color that goes on all over before you paint.

The last couple of steps, I hang the piece in a separate room to dry for several days. This is probably the most important step as this much medium will create quite a bit of fumes if your using oils. Not only is is going to be man oh man stinky, but it could be dangerous to breath as well. I work with ventilation while I’m painting and I move pieces with lots of paint / medium to a separate drying area between stages so that I keep not only myself safe, but my family, friends, and pets too.
