Understanding Gypsum Plaster

Gypsum plaster, also known simply as plaster, is a building material that consists of calcium sulfate dihydrate, derived from gypsum stones through the process of crushing, heating, and hydrating. Chemically speaking, gypsum contains calcium, and sulfur bound to oxygen and water.

The gypsum plaster used for construction purposes is prepared by heating gypsum at low temperatures to drive off some of the chemically combined water. This produces calcium sulfate hemihydrate, also known as plaster of Paris. When we remix this fine white powder with water, it rehydrates and recrystallizes to form gypsum plaster again. This gives us a thick slurry that subsequently hardens into gypsum.

As it sets and hardens, gypsum crystals interlock in different directions forming strong rigid masses. This is what gives gypsum plaster its renowned strength and surface durability, while still being smooth and workable in its wet application state for construction needs.

Uses of Gypsum Plaster

Gypsum plaster is used both internally and externally in construction. Its primary applications include:

• Plastering of wall surfaces as a finishing material over brick, concrete, or drywall structural surfaces. It creates smooth, seamless aesthetic interiors.
• For making architectural designs and decorative cornice and molding features on walls and ceilings.
• Base coat plaster for gypsum boards before applying the final wall paint.
• Model making and casts for shaping ornamental structures.
• Flooring screeds before laying the final flooring.
• Plastering ceilings to create unique patterns and direct light fittings.
• External cement plastering for façade detailing and surface protection against weather.

Importance of Gypsum Plaster

Several beneficial properties make gypsum plaster a preferred choice among builders and interior designers for finishing needs:

• Fire Resistance- Gypsum crystals hold water molecules between their chemical structure. When gypsum plaster is exposed to fire, this chemically combined water gets released slowly as steam, thereby delaying temperature rise. This natural heat resistance allows occupants crucial time to escape in case of accidental fires.
• Temperature Moderation- The water crystals present in gypsum regulate interior temperatures and moisture. During warm weather, excess heat gets absorbed to facilitate the water’s phase change from liquid to vapor, cooling down spaces. In cold weather, the opposite occurs - the crystallization process releases heat to warm up interiors. This maintains comfortable living conditions.
• Noise Reduction- The crystalline composition of gypsum plaster helps to naturally dissipate noise vibrations within structures. Its application on walls also reduces noise penetration for enhanced acoustic insulation.
• Strength- Gypsum mortar and plaster formulations create durable surfaces with high compressive strength and surface hardness. This resistance to indentation, abrasion, and damage makes gypsum suitable for high-traffic areas. Strength also depends on the thickness applied.
• Quick Setting Time- Gypsum products set and reach maximum strength in a matter of hours or days, unlike cement which takes weeks. This allows for fast application, as well as rapid project completion timelines in construction.
• Workability- Wet gypsum is comfortable to work with for extended periods being smooth, pliable to shape, and needing low physical effort to apply. After drying too, it retains its elegant finishing quality. These workability factors enhance productivity.
• Economical Viability- The abundant availability of gypsum rock makes plaster of Paris a very affordable plastering raw material. Being locally producible using simple heating methods, gypsum products are cheaper than many alternative plasters and ornamental materials.
• Aesthetics- Gypsum plaster allows for gorgeous finishing effects. From intricate artistic reliefs, flowers, patterns, and custom 3D modeling to paint-ready blank canvases – gypsum is versatile enough to match a vast array of interior designs and architectural styles.

Factors to Consider Before Buying Gypsum Plaster

 Here are some key factors to consider before buying Gypsum Plaster:

1. Quality - Ensure the Gypsum Plaster conforms to quality standards and certifications. Higher-quality plaster will have greater consistency, strength, and workability. Ask the supplier about quality testing and specifications.
2. Purpose - Consider what the gypsum plaster will be used for (walls, ceilings, patching, molding, etc.). Some types of gypsum plaster are formulated for specific applications. Getting the right variety for the intended use is important.
3. Price - Compare prices from different suppliers. Price can vary significantly depending on the brand, quality grade, and whether it's packaged or bulk. However, don't just choose the cheapest—make sure it meets the quality and suitability needs first.
4. Packaging - Gypsum plaster is packaged as a powder in bags or available in bulk. Assess how much you need and consider storage and handling factors based on packaging type. Bulk is cheaper but requires proper storage facilities.
5. Sand Material - With stucco plasters, consider the type and grain size of sand aggregate that will be mixed with the gypsum. This impacts the final working properties and finish.
6. Reputation of Manufacturer - Check the reputation and reliability of the plaster manufacturer, as this affects consistency and support services. Ask suppliers what brands they recommend.
7. Transportation Cost - Factor in transportation costs if not buying locally. Location and fuel surcharges can add to the overall costs.
