Final answer:

Frescoes resist moisture due to being painted on wet plaster, forming a chemically stable bond that makes them a part of the wall.


Explanation:

Frescoes are not affected by moisture because they are painted on wet plaster, allowing the paint to chemically bond with the plaster as it dries, making it a permanent part of the wall. The buon fresco technique, where pigment is applied to wet plaster, creates a stable bond that withstands moisture without requiring additional binders. Due to this chemical reaction, the pigment becomes fused with the wall, making frescoes resistant to moisture damage.
