What’s happening to a paint when it “cures” after drying?
In: Chemistry
Most house paint these days isn’t just pigment in a liquid: it’s a polymer. Basically like a wet plastic. When it cures, it hardens and goes from liquid to a solid. This allows it to generally be a little waterproof/resistant, stain resistant, and it has some elasticity to prevent scuffs and some marking from being permanent.
