Depends on the type of paper, watercolor painting, and glazing.
The average lifespan of an acrylic painting is 20-30 years. However, with proper care and display, they can last much longer. If an acrylic painting is placed under UV-protective glass or acrylic, it can last over 100 years.
Watercolor paintings on paper will last anywhere from 50 to 300 years, depending on the quality of the paper and the painting itself. If the painting is kept out of direct sunlight and protected from moisture, it will last much longer.
Oil paintings can last for centuries, as long as they are properly cared for. The varnish used on oil paintings protects the paint from oxygen and UV light, which can cause the paint to fade.
To ensure that your painting lasts as long as possible, it is important to display it in a way that will protect it from the elements. For example, if you have a watercolor painting, it should be placed behind glass to protect it from moisture. Oil paintings should also be behind glass, but in a frame that allows for ventilation to prevent the paint from yellowing.
