Does plaster get damaged by water?

Although the level of decoration can vary greatly, water has the power to destroy the work of even the most skilled plaster craftsman. When three-layer plaster gets wet, even slightly, the surface usually shows some visual signs. A brown stain may appear on ceilings or walls. With intensive soaking, the surface may begin to bubble due to the chemical reaction of lime.

As the surface dries, it can harden and the surrounding paint will begin to peel off.

Water damage can be minor and isolated in the

surface layer of the wall, or it can penetrate the entire three-layer structure, causing the brown color to wrinkle and scratch the layers that come off the mesh. In some cases, the mesh may also be damaged and show rotten wood or rusty metal underneath the layers of plaster.
