What is the difference between paint drying and curing?
This is because PAINT DRY and PAINT CURE are two different things. Paint “DRY” happens when the solvents evaporate from your paint coating leaving the paint feeling dry to the touch even though it is not 100% dry. Paint “CURE” happens when your paint coating has reached it’s maximum hardness and is completely 100% dry.
How do you know when paint is cured?
To check if your paint is cured, use the fingernail test. In an inconspicuous area, press your fingernail into the coating. If it leaves an indent, your paint is not fully cured. If no indent is visible and the surface is hard, your paint has most likely cured.

Why does paint not stick to wall?

Why is my fresh paint peeling?
Water causes damage to a freshly painted wall when the surface is exposed to a lot of water over time. Or perhaps there is water finding the wall from within as well. In detail, when water enters through the coats of paint it will detach it from the surface. That’s the reason why cracking and peeling occurs.
