Can I use clear nail polish to seal acrylic paint on canvas? Overall. Yes, you can use clear nail polish to seal tiny rocks painted with acrylics. I hope that this makes it easier to start and have fun with stone painting.
Can hairspray seal acrylic paint?
Acrylic paint, tempera paint and other types of paint that you might use on rocks cannot be sealed with hairspray. Hairspray is neither permanent nor waterproof and some formulations of hairspray and paint react badly to each other and could cause your paint to melt or get gooey!
