Detailed Summary of Case Studies on Plaster Applications
This section elaborates on three practical applications of plaster in construction through case studies, each illustrating distinct challenges, solutions, and results.
Case Study 1: Gypsum Plaster in High-Rise Residential Complex – Mumbai
- Project Overview: A 35-storey residential tower in Andheri East, Mumbai, aimed at enhancing quality while reducing construction time.
- Challenges: Traditional plastering caused delays due to extended curing times and labor inefficiencies.
- Solution: The project transitioned to ready-mix gypsum plaster, which alleviated the need for sand and eliminated curing.
- Outcome: Resulted in a 30% reduction in finishing time, improved safety, and a better finish.
Case Study 2: Lime Plaster for Heritage Restoration – Jaipur Palace
- Project Overview: Restoration of a 200-year-old palace facade that required architectural authenticity.
- Challenges: Cement plaster led to dampness and compromised old lime substrates, necessitating a compatible material.
- Solution: The cement coatings were removed, and lime-sand plaster was reapplied by skilled artisans.
- Outcome: Preserved the palace's heritage aesthetics while preventing moisture issues and enhancing its longevity.
Case Study 3: Cement Plaster with Waterproofing Additives – Coastal Housing Scheme, Kerala
- Project Overview: Development of low-cost housing in coastal Kollam, dealing with moisture issues.
- Challenges: Early paint peeling and dampness due to rain exposure and capillary water rise.
- Solution: Implemented waterproof cement plaster and added a polymer-modified slurry coat.
- Outcome: Achieved durability and significantly reduced maintenance needs, with no flaking observed post-monsoon.

Case Study 1: Use of Gypsum Plaster in High-Rise Residential Complex – Mumbai
Project Overview:
- 35-storey residential tower in Andheri East, Mumbai.
- Objective: Reduce construction time and enhance interior finish quality.
Challenges Faced:
- Delays in conventional plastering due to curing time.
- Labour inefficiencies and inconsistency in manual application.
Solution Implemented:
- Switched to gypsum plaster for all internal walls and ceilings.
- Adopted ready-mix gypsum plaster with no requirement of sand or curing.
Outcome:
- 30% reduction in finishing time.
- Superior finish achieved with less effort.
- Improved worksite cleanliness and safety due to dry application.
Detailed Explanation
In this case study, a 35-storey tower in Mumbai faced delays caused by the curing time required for conventional plastering methods. These delays also led to inefficiencies in labor and inconsistency in the application of plaster. To address these issues, the project switched to using gypsum plaster, specifically a ready-mix option that doesn’t require sand or extensive curing. As a result, they achieved a 30% reduction in the finishing time, a superior finish with less labor effort, and an overall safer and cleaner worksite due to the dry nature of the application process.
Examples & Analogies
Think of it like cooking a meal. If you follow a complex recipe that takes a long time to prepare and cook, you might find yourself overwhelmed. Now, imagine opting for a pre-prepared meal kit that reduces the cooking time and effort. That's what the project did by switching to ready-mix gypsum plaster—making construction quicker and easier while still achieving a great final product.

Case Study 2: Lime Plaster for Heritage Restoration – Jaipur Palace
Project Overview:
- Restoration of a 200-year-old palace facade in Jaipur.
- Requirement: Preserve architectural authenticity with breathable materials.
Challenges Faced:
- Cement plaster caused dampness and damaged old lime substrates.
- Need for material compatible with traditional construction techniques.
Solution Implemented:
- Removed cement coatings and reapplied lime-sand plaster.
- Employed artisans skilled in lime plastering.
Outcome:
- Heritage aesthetics preserved.
- Breathable lime plaster prevented moisture entrapment.
- Increased longevity of facade without further cracking.
Detailed Explanation
This case study focuses on restoring a 200-year-old palace in Jaipur. The original coating of cement plaster was causing dampness and damaging the existing lime substrates, which are historically significant. To preserve the architectural integrity, the cement was removed, and traditional lime-sand plaster was reapplied using skilled artisans. The outcome was the preservation of the palace's aesthetic and structural integrity while ensuring that moisture could escape, preventing further damage and cracking.
Examples & Analogies
Consider restoring an old piece of furniture. If you use harsh modern materials, you might ruin its original charm or functionality. Instead, applying techniques and materials that respect the old craftsmanship will keep the character intact. Similarly, the restoration of the palace required using lime plaster that matched the original method, ensuring that the building retained its historical value.

Case Study 3: Cement Plaster with Waterproofing Additives – Coastal Housing Scheme, Kerala
Project Overview:
- Government low-cost housing near coastal areas of Kollam.
- Frequent rain and high humidity posed durability issues.
Challenges Faced:
- Early peeling of paint and dampness.
- Capillary water rise from foundations.
Solution Implemented:
- Used cement plaster with waterproofing admixtures on both sides of walls.
- Applied a polymer-modified slurry coat as a base.
Outcome:
- Walls showed no efflorescence or flaking after monsoon.
- Increased lifespan of interior paint and finishes.
- Reduced maintenance needs by over 50%.
Detailed Explanation
The final case study highlights a low-cost housing initiative in Kerala, where challenges like high humidity and frequent rain led to issues such as paint peeling and dampness. To address this, the project utilized cement plaster mixed with waterproofing additives on both sides of the walls, along with a polymer-modified slurry as a base layer. This strategic approach notably improved the durability of the walls, resulting in no efflorescence or flaking after the rainy season and significantly extending the lifespan of interior finishes. Maintenance needs were also cut by over half.
Examples & Analogies
Imagine living in a home in a rainy area. If you use ordinary paint without any waterproofing, it will start peeling and look worn out quickly. But if you choose a brand that specifically protects against moisture, your walls will stay beautiful and intact longer. Similarly, the cement plaster with waterproofing additives acted like that protective paint, safeguarding the homes in the coastal housing scheme from the challenges presented by the environment.
