A fresco painting is a type of painting done on wet plaster. This is one of the hardest art forms to correct if a mistake is made. Instead of being able to add more paint easily or being able to cover it out with white paint when it’s dry, a mistake in fresco has to be chiseled out. Often, the painter will have an idea of what they want to draw before they start on a fresco.
One of the most famous fresco paintings is the ceiling of the Sistine Chapel in the Vatican. It was done by Michelangelo. The process took a long time, because the builders couldn’t plaster more than Michelangelo could paint in a day. Today, it’s admired by tourists around the world.
