Advantages and disadvantages of Gypsum Plaster

Advantages of Gypsum Plaster

  1. Easy to apply and shape – Gypsum plaster goes on walls and ceilings smoothly and can be easily molded into different shapes, making it convenient for decorative purposes.
  2. Quick setting time – It sets and dries faster than many other plasters, which helps speed up the construction process.
  3. Smooth finish – Once dried, it leaves a uniform, velvety surface that doesn’t usually need sanding, creating a high-quality look with less effort.
  4. Non-combustible material – Being non-flammable, gypsum plaster can help slow the spread of fires, adding an extra layer of safety to buildings.
  5. Resistant to mold and mildew – It doesn’t support the growth of fungus or bacteria, keeping indoor spaces healthier and reducing maintenance work related to moisture damage.

Disadvantages of Gypsum Plaster

  1. Not suitable for damp areas – Gypsum plaster doesn’t hold up well in places with a lot of water or moisture, like bathrooms or basements. It can absorb water and get damaged.
  2. Can crack over time – Over the years, gypsum plaster might develop cracks because it doesn’t flex much. This means it can’t move with your house if it settles or shifts.
  3. Slower drying process – It takes more time for gypsum plaster to dry compared to other types, which means you have to wait longer before you can paint or finish the wall.
  4. Poor impact resistance – If something hits a wall with gypsum plaster, it can easily get dented or get a hole because it’s not very tough against knocks or bumps.
  5. Limited outdoor use – Gypsum plaster isn’t the best choice for outside walls because weather like rain, sun, and wind can harm it, making it not last as long.

That’s it.
