There are numerous reasons which can be counted when we are talking about the crumbling plaster. It is required to look first at the causes of the Peeling plaster before diving into the remedies. Here, we will list down some of the very important causes of the crumbling Plaster.

1. Increasing dampness or moisture in the walls: This can be considered the primary reason for the crumbling or peeling plaster. When moisture enters the plaster, the plaster begins to get thicken and start falling apart from the wall.

Let’s try to discuss this in a little detail. Why Dampness occurs in walls?

Dampness occurs in walls due to seepage. Seepage generally indicates the flowing of water or any gas in a little quantity from the small pores or holes of any hard object.

Water Seepage takes place due to the following factors:-

  •  Holes in the drainpipe, leakages in the washroom, cookhouse, or storage tank.
  • Leakages in the water distribution channel, bathroom washbasin, and drainage pipeline.
  • Washroom tile flooring leaks also constitute wall seepage.
  • Malfunctioning of gas, and water connections.
  • In case the outer walls of the infrastructure are not plastered.

Deformed Glassdoor framework or window structure or liners can also result in wall seepage.

2. Old Age: Plaster gets weaker as it gets older and can start falling apart.

3. Shaking or Moving: If there’s a lot of vibration from things like construction work or heavy machines nearby, the plaster can get damaged and start to crumble.

4. Structural Issues: Cracks in the building’s structure can cause stress on the plaster, making it crack and crumble.

5. Bad Application: If the plaster wasn’t put on properly when the building was made or fixed, it might not stick well and could eventually fall off.

6. Chemicals: Sometimes, chemicals like cleaning products or pollutants in the air can react with the plaster and make it break down.

7. Temperature Changes: Big changes in temperature can make the materials in the wall expand and contract, which can lead to cracks and peeling plaster.

8. Bugs: Certain pests, such as termites or carpenter ants, can damage the wood that holds the plaster, causing it to become loose and fall apart.

So, this was a basic outlook of the causes of the crumbling or eroding plaster.
