    Constructing the dream house is something that every person aspires to. Constructing a home with aspired structural integrity and elegance requires the building professionals and homeowners to take the required measures. Gypsum plaster is a commonly used material that provides the home with the required interior and ceiling finishing. An experienced professional with the skill and understanding can use gypsum plaster appropriately and create decorative finishes like crown moulding and cornices.

    The gypsum plaster is used to prepare thick layers on the exterior walls that provide them with the required water resistance. It is a material that facilitates the creation of a variety of objects like sculptures, figurines, and decorative pieces. The fire resistance of the gypsum plaster makes it a suitable fit for firewall and fire door creation. Multiple other uses of gypsum plaster make it a suitable material for creating the finest structures. One must have the required understanding regarding gypsum plaster to employ it sensibly. Through the following passages, different aspects of gypsum plaster and common mistakes one must avoid while using them will be depicted with the required details. 


    Gypsum Plaster- A Brief Introduction


    Gypsum is a soft sulfate mineral that is the primary constituent of gypsum plaster. With its white powdery-like texture, it is ready for application when mixed with water. It is a versatile material that is widely preferred by building professionals and homeowners for its distinct qualities and relatively low cost. Here are some of the advantages of gypsum plaster that make it the best choice:-

    • Smooth and Even Finish: Gypsum plaster enables the user to create a smooth and even finish required for painting and wallpapering. 
    • Ease in Application: It gets ready for application after mixing with water, providing it with the required ease in application. 
    • Fire-resistance: The fire-resistance of the gypsum plaster makes it an appropriate material for providing the required resilience against fire. 
    • Soundproofing: It is an appropriate material to create the required shield against noise.

    Different Types of Gypsum Plaster


    Following are the types of gypsum plasters that are used widely in the market:-

    Perlite-Based Gypsum Plaster: Gypsum, a soft sulfate mineral, and perlite, a volcanic glass expanded by heat, are the main constituents of perlite-based gypsum plaster. Added perlite to this gypsum plaster makes it lighter and more insulating. 

    Following are the benefits of using perlite-based gypsum plaster:-

    • Lightweight: It is lightweight and less likely to form cracks. Its lightweight also provides it with the ease of application. 
    • Added Insulation: The insulation properties of perlite enable it to reduce energy costs. 
    • Better Approach to Plastering: The use of perlite-based gypsum plaster is a better alternative to traditional plastering and is less likely to develop holes or cracks. 

    Vermiculite-based Gypsum Plaster: A mixture of gypsum, a soft sulfate mineral, and vermiculite, a mica-like mineral expanded by heat, creates the vermiculite-based gypsum plaster. The added vermiculite makes this gypsum plaster more insulating and fire-resistant. The following are the advantages of using vermiculite-based gypsum plaster:-

    • Incombustibility: These are less prone to ignition and contribute to the creation of fireproof buildings. 
    • Compressibility: The compressibility of this gypsum plaster makes it easy to apply and shape the surfaces. There are fewer chances of cracking by the use of vermiculite-based gypsum plaster. The compressibility of this material also contributes to the creation of long-lasting structures. 
    • Non-reactive: The non-reactiveness of this gypsum plaster makes it an ideal material for use in labs and areas prone to chemical residue. 
    • High Cation Exchange Capacity: A vermiculite-based gypsum plaster effortlessly absorbs the moisture from the air. This gypsum plaster provides better drainage properties to the material.

    Block Joining Mortar


    It is used to join concrete blocks and is a heterogeneous blend of cement, sand, and water. With its application as a thin layer between the blocks, it serves its purpose. Its application creates a stronger bond between the blocks and provides the required resistance against damage and cracking. There are multiple types of block joining mortar having specific properties, making them suitable for distinct applications. The following are the advantages offered by block joining mortar:-

    • The mix feature of the mortar eliminates the requirement for storage. 
    • The application of mortar makes the walls more strong and improves their durability. 
    • The use of block mortar facilitates a regulated heat flow through walls. 
    • There are no cases of seepage and water percolation during and after the material’s application. 
    • One can achieve better levelling and prevent the surface from shrinkage or cracks.

    Common Mistakes That May Cause Adverse Effects


    Despite the benefits, one should be cautious while using the gypsum plaster. Making a mistake in the application may cause adverse effects, which may require additional input from the user. The following are the things one must consider to avoid unintended outcomes while using gypsum plaster:-

    • Quality of Gypsum Plaster: One must select the best gypsum plaster available. Gypsum plaster must have the required precision in its constituents. The quality of the material increases the likelihood of delivering the desired outcomes to the user. Without the same, there is a high likelihood of compromising the structure’s integrity. 
    • Making an Appropriate Selection of Gypsum Plaster: There are different types of gypsum plasters, each catering to their purpose. Making an appropriate selection is important to have the desired outcome. For example, the gypsum plaster suitable for interior use does not provide the desired outcome for exterior applications. 
    • Mixing the Plaster Incorrectly:  There must be a required proportion of water added to the gypsum plaster to provide it with the required efficacy. Any imbalance causes difficulty in application or does not serve the purpose of application. 
    • Not Providing Enough Time for Plaster to Dry: Plaster must be dried before it is subjected to other applications like painting or another finish on its surface. If adequate time is not provided peeling or bubble formation are common. 
    • Not Sealing the Plaster: Gypsum plaster is a porous material which proactively absorbs water and moisture. If not sealed properly, it becomes damp and mouldy. 
    • Not Using Appropriate Tools and Safety Equipment: The use of the required tools is necessary to apply the gypsum plaster evenly on the surfaces. One also needs to wear dust masks and goggles while working with them to avoid dust projections on the skin and eyes.

    Concluding Remarks


    Gypsum plaster is a material that allows users to create even surfaces for the surfaces. Different types of gypsum plaster serve distinct purposes. Appropriate use of gypsum plaster allows users to have the best possible outcomes from using them and avoid unintended outcomes.
