Q1: What is the best type of plastering for interior walls in humid climates? 

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, we can use buildon gypsum plaster but it’s best if 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? 

Gypsum plaster typically sets within 20–30 minutes, and the surface can be ready for painting after about a day or two, 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? 

It’s recommended to use a bonding agent like Plaster Bond+, 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? 

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? 

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
