1. Cracking

Cause: Rapid drying, structural movement or incorrect mix ratios can contribute to cracks in plaster.

Fix: Gypsum plaster has a controlled setting time and can help reduce shrinkage-related cracks when mixed and applied correctly. Significant structural cracks should be assessed and repaired separately before plastering.

2. Blistering and Bubbling

Cause: Trapped air, surface contamination or moisture beneath the plaster can cause blistering and bubbling.

Fix: Proper surface preparation and strong bonding are essential. Gypsum plaster can help create a more uniform finish when applied to a clean, suitable substrate without trapped air or active moisture.

3. Efflorescence

Cause: Efflorescence occurs when soluble salts migrate to the surface due to moisture movement through the wall.

Fix: Gypsum plaster requires no water curing, which can help reduce moisture introduced during the plastering process. However, the underlying source of moisture must be identified and treated before application.

4. Delamination

Cause: Poor adhesion between the plaster and the substrate can cause the plaster layer to detach or peel away.

Fix: Gypsum plaster can bond strongly to suitable brick, block or concrete surfaces when the substrate is properly prepared. Remove dust, loose material and other contaminants before application.

5. Crumbling and Powdery Surfaces

Cause: A weak plaster mix, poor-quality materials or improper curing can lead to surface dusting, crumbling and powdering.

Fix: Gypsum plaster can provide a stronger and more durable surface when mixed and applied as recommended. A weak or unstable substrate should be repaired before plastering.

6. Uneven Finish

Cause: Poor workmanship, inconsistent mix quality or uneven application can result in an irregular wall finish.

Fix: Gypsum plaster spreads easily and can help achieve a smoother, more polished surface. Proper levelling, application technique and final finishing remain essential for the best result.

7. Slow Drying and Dampness

Cause: Conventional cement plaster may require prolonged curing and drying, which can extend construction timelines and contribute to moisture-related delays.

Fix: Birla White Gypsum Plaster sets quickly, typically within approximately 25–30 minutes depending on site conditions and product guidance, and requires no water curing. This can help reduce construction time and minimise curing-related dampness.

Always follow the product manufacturer's technical instructions for mixing, application, setting time and drying requirements.

Gypsum plaster offers practical advantages that make it a preferred choice for many modern construction projects. Its quick-setting property can save valuable time, allowing work to progress faster without compromising the quality of the finish.

Since gypsum plaster requires no water curing, it can significantly reduce water usage and minimise curing-related delays. The smooth finish it provides may also reduce the need for additional putty before painting, depending on the selected paint system and the final surface condition.

Gypsum plaster is also suitable for a range of residential and commercial interior applications. It can provide durable, aesthetic and more sustainable results when applied to suitable surfaces by following the manufacturer's instructions.

After plastering, proper surface preparation remains important before applying wall putty or paint. Explore the correct wall finishing and putty application process for the next stage of your project.
