Another panel from The Monochromes group, recently completed:
I posted about the progress on this painting here and here. Now the sides have been painted silver and I've successfully applied two coats of gloss varnish.
I'll be honest: I do not enjoy applying varnish! There are so many factors involved in getting it right. Studio conditions must be just so: hot but so humid; and windows closed and ceiling fan off to eliminate dust blowing around. Using a high quality brush is very important, as is preventing bubbles. I thin the varnish with 25% water. I have to work quickly. In this environment, the varnish takes ages to cure. But when it's done correctly, the painting is luminous. Success!
