# What is the difference between UV damage and heat damage on a wall? | Time Paints

UV damage shows as fading, loss of sheen, and a chalky powder on the surface, while the paint stays attached to the wall. Heat damage shows as cracking, blistering, and peeling from the wall expanding and contracting. UV is a color problem; heat is a physical-failure problem, and they often happen together.
