Paint and water are insoluble, and an easy way to identify if your plaster is damaged by water is to look for peeling paint or air bubbles that burst and flake off. Water-damaged gypsum occurs (obviously) when water is present. A little water is not a problem, you can clean it right away.

When three-layer plaster gets wet, even slightly, the surface will usually show some visual signs. A brown stain may appear on ceilings or walls. With intense soaking, the surface may begin to bubble due to the chemical reaction of lime. As the surface dries, it may harden and the surrounding paint will begin to peel off.
Water damage effects may be minor, isolated from the surface layer of the wall, or can penetrate the entire 3-layer structure, causing brown and scratched layers to fall off the batten to crumble. In some cases, the batten may also be damaged, showing rotten wood or rusty metal under the layers of plaster. Before repairing the damaged drywall, first fix the cause of the leak, clean the affected surface and make sure that it is completely dry. If the area is larger, it makes sense to replace the old damaged plaster with a new layer.
Print and seal the surface to block bleeding stains. When it is completely dry, you can paint the plaster. Softened drywall is the most forgotten sign of water damage to the wall. Softening occurs when the back of the drywall is soaked, but the outside looks normal.

There is a good chance that water damage has occurred behind the wall; like the other indicators, this could lead to mold.
If the damage to your wall is excessive, call someone who knows how to repair plaster walls damaged by water. Over time, water can be absorbed from the foundation masonry (or into the outer stone walls) and damage any plaster applied to it. Using a bucket of clean water and a sponge, wash the surrounding area as a final cleaning exercise, and then let the water-damaged plaster wall dry completely. There may be invisible problems due to water damage lurking behind the wall, such as mold, rot and electrical hazards.
In most situations, a pipe or gutter has been damaged or removed from its location, allowing water to flow where it shouldn't go. Simply eliminating salt buildup will not address the underlying problem and an expert should be consulted to determine the extent of the damage and what potential damage could occur if left untreated. There is a slight risk that water will continue to flow through the hole, but if you are aware of the threat, you can take steps to mitigate the damage with towels.
