Why should we use gypsum plaster instead of conventional sand cement plastering?

Sand cement plastering is a time-consuming and messy affair. You need to procure different raw materials like sand, cement, water and aggregates separately and then mix them on site. Sand cement plastering also requires water curing for at least seven days, which makes the process extremely labour-intensive and time-consuming. What’s more, using fine river sand is not eco-friendly as it involves dredging rivers which causes harm to the environment. So, gypsum plaster is fast becoming the preferred option to plaster internal ceilings and walls. It is ready to use, requires no water curing and is labour-friendly and faster than sand cement plastering. It also delivers a crack-free and smooth finish.

What is the difference between gypsum plaster and POP?

Plaster of Paris (POP) is a hemihydrate calcium sulphate with no additives in it, which means that setting time is unregulated, resulting in a lot of wastage and also formation of cracks. Gypsum plasters contain specially formulated additives to take care of high background suction. So, they are used for application on high, moderate or low suction backgrounds like red bricks, concrete blocks, AAC blocks and RCC. The special additives ensure high spread (coverage) and increased setting time which reduces wastage and eliminates shrinkage cracks.

What is the gypsum plaster durability ?

Lifelong: This plaster is formulated with high purity gypsum having free from lime and other contamination. Other ingredients and aggregates used also are natural. Thus it provides a strong and durability to the back ground.

How does a ceiling system reduce air-conditioning needs and help lower electricity bills?

False ceilings provide thermal insulation by creating an air gap between the soffit and the false ceiling. They reduce the air volume of a room and, as a result, the air-conditioning load. Thus, the air-conditioning requirement is reduced, resulting in lower electricity bills.

How does a ceiling system reduce air-conditioning needs and help lower electricity bills?

Ceilings reflect and diffuse light. A ceiling that reflects and diffuses light well reduces the need for artificial lighting. This results in improved energy efficiency and a better working environment.

What is the key performance criteria while selecting a good ceiling system?

The important criteria for selecting a good ceiling system are: Acoustic performance: A ceiling should have good acoustics. It should enhance required sound, while eliminating or reducing unwanted sound. Light efficiency: A ceiling that reflects and diffuses light well reduces need for artificial lighting. The result is improved energy efficiency and a better working environment. Accessibility and service management: An important function of a suspended ceiling is concealing the plumbing, the air-conditioning system and electrical wiring. A good ceiling system also enables ease of access to such ducts and wires. Other functional parameters: Apart from these parameters, fire safety, moisture resistance, ease in cleaning, load-bearing capacity, installation and environment friendliness are important.

Can drywalls walls be used for external walls?

Gypsum plasterboard based drywalls are suitable only for interior applications (including shaft and bathroom walls).

How strong are drywalls?

Drywalls can be built as strong as you want and are typically strong enough to take the requisite abuse of a normal application.
