One of the most common causes of damage in internal plaster walls is leaks in plumbing or roofing. These leaks can go undetected for a long time, causing damage to the plaster and other building materials. 

Flooding is another common cause of damage, and it can happen due to heavy rains, storms, or even broken pipes. Humidity and condensation can also cause damage, especially in areas with high humidity or poor ventilation. To determine the source of the damage, it’s important to inspect the walls and the surrounding areas for signs of moisture or leaks.

Once the source of the damage has been identified, it’s essential to assess the extent of the damage. This involves inspecting the plaster for cracks, warping, or other signs of damage. It’s also important to determine the type of plaster and the best course of action. Safety precautions must be taken when assessing the damage, as the plaster may be unstable and could collapse.

Removing Water Damaged Plasterboard

Removing damaged plaster is the next step in the plastering process. This can be done manually with a hammer and chisel or with a power tool such as a rotary hammer. It’s important to remove all of the damaged plaster, including any that may have become loose or unstable. 

Preparing the walls for re-plastering involves cleaning the surface, removing any remaining debris, and ensuring that the walls are dry and stable. Disposing of damaged plaster safely is also important to avoid contaminating the environment.
