When building or renovating your home, choosing the right type of plastering for your interior walls is crucial for both aesthetics and functionality. From the traditional lime plaster used in heritage buildings to modern gypsum solutions, the plastering landscape in India has evolved significantly. Whether you’re constructing a new home in Mumbai or renovating an apartment in Bangalore, understanding the various plastering options available can help you make an informed decision that ensures durability, cost-effectiveness, and visual appeal.
Interior wall plastering isn’t just about creating a smooth surface it’s about selecting the right material that complements your climate, construction method, and long-term maintenance preferences. Let’s explore the different types of plastering for interior walls and help you choose the best option for your project.
Traditional Cement Sand Plaster
Cement sand plaster remains one of the most popular plastering methods in Indian construction. This traditional approach involves mixing cement, sand, and water in specific proportions to create a strong, durable surface.
Advantages of Cement Sand Plaster:
- Exceptional strength and durability
- Cost-effective for large projects
- Suitable for all weather conditions
- Easy availability of materials across India
- Can be used for both interior and exterior applications
Disadvantages:
- Requires skilled labour for proper mixing and application
- Longer curing time (typically 7–28 days)
- Needs extra water curing, which consumes more resources and increases overall cost
- Prone to cracking if not properly mixed
- Heavier weight adds to the structural load
The typical mixing ratio for interior walls is 1:4 or 1:6 (cement:sand), depending on the specific requirements and local practices. In regions like Tamil Nadu and Kerala, where humidity levels are high, cement sand plaster provides excellent moisture resistance.
Gypsum Plaster: The Modern Solution
Gypsum plaster has revolutionised interior wall finishing in Indian construction. This modern alternative offers numerous advantages over traditional cement-based solutions and has become increasingly popular in urban construction projects.
Key Benefits of Gypsum Plaster:
- Better setting time (typically 20-30 minutes)
- Smooth, ready-to-paint finish
- Excellent adhesion to various surfaces
- Thermal insulation properties
- Crack-resistant formulation
- No curing required

Choosing the Right Type of Plastering for Your Interior Walls
Consider Your Climate
In humid coastal regions like Mumbai, Chennai, and Kochi. For areas with extreme temperature variations, thermal insulation properties become crucial.
Evaluate Your Timeline
If you’re working on a tight construction schedule, gypsum plaster’s quick setting time can significantly reduce project duration. Traditional cement sand plaster requires longer curing periods, which might not suit fast-track projects.
Budget Considerations
While gypsum plaster may have slightly higher material costs, it often proves to be more cost-effective in the long run. Its quick application, minimal labour requirements, and elimination of water curing lead to faster project completion and reduced overall expenses. When evaluating costs, it’s essential to consider not just materials but also time, labour, and project efficiency.
Surface Preparation Requirements
Different types of plastering require varying levels of surface preparation. Gypsum plaster requires bonding agent on RCC walls, RCC structures & on joints between Siporex blocks & RCC structures, ensuring proper adhesion and longevity.
Application Best Practices
For Gypsum Plaster Application:
- Ensure surface is clean and dust-free
- Apply bonding agent if required
- Mix plaster as per manufacturer’s instructions
- Level and smooth surface before setting
For Cement Sand Plaster:
- Prepare surface by cleaning and Hydrating
- Apply in two coats – rough coat and finishing coat
- Maintain proper curing for 7-28 days
- Ensure adequate protection from direct sunlight and wind
Maintenance and Longevity
The lifespan of interior plastering depends significantly on the chosen material and application quality. Gypsum plaster, when properly applied, can last 15-20 years without major maintenance. Quality products from established manufacturers like Buildon ensure consistent performance and durability.
Regular inspection for cracks, moisture penetration, or surface deterioration helps maintain the plaster’s integrity. Most gypsum plasters are ready for painting immediately after application, reducing overall project time.
Conclusion
Selecting the right type of plastering for interior walls depends on various factors including climate, timeline, budget, and specific project requirements. While traditional cement sand plaster remains viable for many applications, modern gypsum solutions offer superior convenience, finish quality, and time savings.
For Indian construction projects, companies like Buildon Plasters provide comprehensive solutions ranging from basic gypsum plaster to specialised thermal insulation options. Their products’ proven track record in projects across Mumbai, Bangalore, Chennai, and other major cities demonstrates the reliability of modern plastering solutions.

Frequently Asked Questions
Q1: What is the best type of plastering for interior walls in humid climates?Â
While gypsum plaster offers a smooth finish and faster application, it is not moisture-resistant and is not recommended for wet areas like bathroom walls. For humid climates, it’s best used in dry interior spaces, while cement-based plasters are more suitable for moisture-prone areas.
Q2: How long does gypsum plaster take to dry compared to cement plaster?Â
Gypsum plaster typically sets within 20–30 minutes, and the surface can be ready for painting after about a day, depending on site conditions and ventilation. In contrast, cement sand plaster requires 7–28 days of curing before painting can begin.
Q3: Can I apply gypsum plaster directly on concrete surfaces?Â
It’s recommended to use a bonding agent like BONDIT-151 when applying gypsum plaster on concrete blocks or RCC surfaces for proper adhesion.
Q4: Which plastering type is more cost-effective for large residential projects?Â
While gypsum plaster has higher material costs, it’s often more cost-effective overall due to reduced labour time, no curing requirements, and immediate painting capability.
Q5: What is the coverage area of gypsum plaster per bag?Â
Coverage varies based on the product type and wall conditions. For Buildon’s standard gypsum plaster:
- A 25 kg bag covers approximately 20 sq. ft. at 12mm thickness
- A 20 kg bag covers approximately 16 sq. ft. at 12mm thickness
For Buildon’s Perlite-based gypsum plaster, coverage is higher—around 24 sq. ft. at 12mm thickness. Actual coverage may vary slightly depending on surface smoothness and application method.
