OPC is suitable for general-purpose plastering, while PPC offers enhanced workability and durability, making it suitable for plastering in areas prone to water exposure.

Lime Cement

Lime cement, also known as hydraulic lime, is made by burning limestone and is known for its excellent workability and breathability. Lime cement plaster is suitable for historic restoration projects and traditional construction methods where breathability and flexibility are essential. It allows moisture to evaporate from the plastered surface, preventing moisture buildup and mould growth. Lime cement plaster is also preferred for its aesthetic appeal and ability to create smooth finishes.

Gypsum Cement

Gypsum cement, also known as plaster of Paris, is a type of cement that is primarily composed of gypsum. It is widely used for interior plastering applications, such as finishing walls and ceilings in residential and commercial buildings. Gypsum plaster sets rapidly when mixed with water, allowing for quick installation and finishing. It provides a smooth, uniform surface that is easy to paint or decorate.

Masonry Cement

Masonry cement is a blend of Portland cement, lime, and other additives designed specifically for masonry applications, including plastering. It offers excellent workability, adhesion, and durability, making it suitable for plastering exterior walls, brickwork, and block walls. Masonry cement provides good weather resistance and bond strength, making it suitable for plastering in areas exposed to harsh environmental conditions.

Polymer-Modified Cement

Polymer-modified cement is a type of cement that is blended with polymer additives to improve its adhesive properties, flexibility, and durability. Polymer-modified cement plaster offers enhanced resistance to cracking, shrinkage, and water penetration, making it suitable for plastering exterior walls, facades, and areas prone to movement or structural stress.

When selecting the appropriate cement for plastering, it’s essential to consider the specific requirements of the project, including the type of substrate, environmental conditions, desired finish, and performance characteristics needed. Consulting with a qualified engineer or contractor can help ensure the proper selection and application of cement for optimal plastering results.

What Is The Standard Cement Plaster?

Standard cement plaster typically refers to a plastering mixture made primarily of Portland cement, sand, and water. This mixture is commonly used for interior and exterior plastering applications in construction. The proportions of cement, sand, and water can vary depending on factors such as the desired strength, workability, and finish of the plaster.

The standard ratio for mixing cement plaster is typically 1 part cement to 3 or 4 parts sand, although variations in the ratio are common depending on the specific requirements of the project. Water is added gradually to achieve the desired consistency for application.

Standard cement plaster offers several advantages, including:


  • Strength and durability: Portland cement provides excellent bonding strength and durability to the plaster, ensuring long-term structural integrity.


  • Versatility: Cement plaster can be applied to various substrates such as brick, concrete, and masonry, making it suitable for both interior and exterior surfaces.


  • Resistance to weathering: Cement plaster offers good resistance to weathering, moisture, and environmental factors, making it suitable for exterior applications subject to harsh weather conditions.


  • Smooth finish: With proper application and finishing techniques, cement plaster can provide a smooth and uniform surface ready for painting or decorative finishes.


  • Cost-effectiveness: Cement plaster is generally more cost-effective compared to other types of plastering materials, making it a popular choice for construction projects.


Standard cement plaster is a versatile and widely used plastering material known for its strength, durability, and suitability for a range of construction applications. However, it’s essential to ensure proper mixing, application, and curing procedures to achieve optimal results and long-lasting performance.

Importance Of Plastering

Plastering plays a crucial role in construction and building maintenance, offering several important benefits:


  • Protection: Plastering provides a protective layer over the structural elements of buildings, such as walls and ceilings, shielding them from weathering, moisture, and physical damage. It helps to extend the lifespan of the underlying materials and maintains the structural integrity of the building.


  • Aesthetic Appeal: Plastering enhances the appearance of interior and exterior surfaces, providing a smooth, uniform finish that serves as a base for painting, wallpapering, or decorative treatments. Well-executed plastering can significantly improve the visual appeal of a building, creating a pleasing and cohesive look.


  • Surface Preparation: Plastering ensures that surfaces are properly prepared for subsequent finishes or treatments, such as painting, tiling, or wallpapering. It helps to create a clean, level, and uniform substrate, eliminating imperfections and irregularities that could affect the quality of the final finish.


  • Insulation: Certain types of plastering materials, such as thermal plaster or insulating plaster, can improve the thermal and acoustic insulation properties of buildings. These specialized plasters help to regulate indoor temperatures, reduce energy consumption, and enhance occupant comfort.
