Instead of Portland cement, gypsum is employed as a binding element in gypsum plaster. Gypsum plaster is a white cementing substance made from the mineral gypsum that has been partially or completely dehydrated. Dry gypsum powder becomes cemented when combined with water. It comes in a ready-to-use format and does not require sand. All that is needed is some water. It has outstanding acoustic and thermal properties, as well as leveled and finished walls.

Gypsum plaster creates a smooth interior finish and is an excellent foundation for high-quality paint and wallpaper. It can be used on both smooth and uneven wall surfaces. Unlike typical cement mortar, gypsum plaster is simple to apply and requires less specialized labor. To avoid cracks and peeling, the surface should be properly prepared and the gypsum plaster applied.

Storage of Gypsum

The setting time and strength of gypsum plaster are reduced when exposed to dampness. Gypsum bags must therefore be stored on an elevated, dry platform composed of wood, brick, or concrete. Gypsum plaster has a shelf life of 3-4 months from the date of manufacturing. Its shelf life can be extended by another 6 months if properly stored at the right temperature and humidity.

Gypsum Plaster Thickness

It comes in a range of thicknesses from 6mm-20mm. Gypsum plaster undercoats are normally 11mm thick for walls and 8mm thick for ceilings, with a 2mm final coat. To avoid cracks, a minimum thickness of 6mm gypsum plaster is advised. If a wall requires more than 20mm of plaster built up, an initial dash coat of cement sand plaster for a thickness of 8-12mm is placed, followed by gypsum To achieve a smooth finish, add another 6mm of plaster to the remaining thickness.

Gypsum Plaster Application

Gypsum plaster is applied in the following manner after surface preparation.

Gypsum Plaster is usually sold in ready-to-use bags. In a clean, dry jar, extract the powder, add the water, and whisk for 2-3 minutes.

Make sure the required plaster thickness is less than 13 mm.

Apply hard pressure to the gypsum plaster surface.

Continue to flatten the plaster as it stiffens. When the plaster is hard enough, scrub the surface with a sponge float and water as needed.

To get a smooth finish, trowel the surface gradually.

Continuous moisture exposure to the plastered surface should be avoided.

Painting work should only begin until the surface has completely dried.

Gypsum Plaster Properties

Because it is light, its use for plastering does not add to the structural strain on the building.

Gypsum plaster, unlike cement plaster, does not shrink throughout the drying and hardening process.

It's less likely to crack.

Gypsum is a non-combustible mineral with a high concentration of crystal water. It works as a barrier in the event of a fire, protecting the blockwork, concrete, and steel.

Metal fittings, such as pipes, are protected from rusting by gypsum plaster, which also boosts their endurance.

Because gypsum plaster has a low thermal conductivity, it saves energy and power.

Gypsum plaster has excellent tensile and flexural properties.
