Is Your House Damp? Check the Plaster First!

Have you ever felt like your house feels stuffy, cold, or even moldy, even though it's not the rainy season? One of the causes could be substandard wall plaster!

Why is Plastering Important?
Plastering is a layer of cement applied directly to the surface of a brick or concrete wall before finishing and painting. Its function is not only to level the walls, but also:

• Prevents moisture from outside from entering the room
• Protects bricks from premature decay or cracking
• Provides a good base for finishing processes (plaster and paint)

Signs of Problematic Plaster
If you find these signs at home, your plaster may need to be re-inspected:

🔸 Walls feel cold and wet to the touch
🔸 Mold or moss stains appear in the corners of the walls
🔸 Wall paint peels easily
🔸 There's a musty odor indoors

Causes of Plaster Failure

1. Incorrect mortar composition
   Too much sand or water can make the plaster brittle and easily absorb water.
    
2. Not using instant mortar
   Instant mortar has a more stable mix and better adhesion than manual mortar.
    
3. Not using a waterproofing layer
   For exterior walls or walls near bathrooms, a waterproof coating is mandatory to prevent moisture.
    
4. Rushed application process
   Walls that haven't dried when plastered or painted will retain water.

The solution?
✅ Use quality instant mortar for a solid, moisture-resistant plaster finish.
✅ Add a waterproofing layer to the exterior walls.
✅ Ensure the plaster is completely dry before proceeding to the plastering or painting stage.
✅ Consult your building materials supplier if you have any doubts about product quality.
