Gypsum vs. Plaster of Paris: What’s the Difference and Which One is Right for You?

When it comes to construction and interior design, two popular materials often come into the spotlight: gypsum and plaster of Paris (POP). Both have unique properties that make them indispensable for various applications. Understanding the difference between gypsum and plaster of Paris is crucial for choosing the right material for your project. This blog will guide you through their differences, benefits, and applications to help you make an informed decision.

What is Gypsum?

Gypsum is a naturally occurring mineral composed of calcium sulfate dihydrate. It is widely used in the construction industry due to its versatility and eco-friendly nature.

Key Features of Gypsum:

• Natural Origin: Extracted from natural deposits.
• Fire Resistance: Gypsum is inherently fire-resistant, making it ideal for safety-focused applications.
• Durability: Offers a robust and long-lasting finish.
• Eco-Friendly: Non-toxic and recyclable.

What is Plaster of Paris?

Plaster of Paris, commonly referred to as POP, is derived from gypsum. When gypsum is heated to approximately 150°C, it loses water and forms a quick-setting material known as plaster of Paris.

Key Features of Plaster of Paris:

• Quick Setting: POP sets faster compared to other materials.
• Smooth Finish: Provides a fine and smooth surface ideal for decorative work.
• Lightweight: Easy to handle and apply.
• Versatility: Widely used for moldings, sculptures, and false ceilings.
