What is The Operation Procedure of Gypsum Plastering

Gypsum plastering, also known as plaster of Paris or POP, is a widely used material in construction for its excellent fire resistance, soundproofing properties, and ease of application. It is a white powder that is made from the mineral gypsum and can be used for both internal and external walls.

Gypsum work in Qatar has gained popularity due to its fire resistance and durability, making it a popular choice for commercial and residential buildings. In this blog, we will discuss the operation procedure of gypsum plastering in detail.

  • Preparation of Surface

The first step in the gypsum plastering process is the preparation of the surface to be plastered. The surface must be clean, dry, and free from any dust, dirt, or loose material. Any cracks or holes in the surface should be filled with a suitable filler, and any protrusions or unevenness should be smoothed out.

  • Application of Primer

Once the surface is prepared, a primer is applied to it. A primer is a thin layer of material that helps the plaster to adhere to the surface and ensures a smooth finish. The primer can be applied using a brush, roller, or spray, depending on the size of the surface.

  • Mixing of Plaster

The next step is to mix the plaster. Gypsum plaster is typically mixed with water in a ratio of 1:2, which means one part of plaster is mixed with two parts of water. The mixture should be stirred well to ensure that there are no lumps and it has a smooth consistency. It is essential to use clean water for mixing the plaster.

  • Application of Plaster

Once the plaster is mixed, it can be applied to the surface. The plaster is typically applied in two or three coats, depending on the thickness required. The first coat is known as the scratch coat and is applied using a trowel. The scratch coat is used to provide a rough surface for the second coat to adhere to.

The second coat is known as the brown coat and is applied once the scratch coat has dried. The brown coat is used to level the surface and provide a smooth finish. The third coat, known as the finish coat, is applied once the brown coat has dried. The finish coat is used to provide a final smooth finish.

  • Finishing

Once the final coat has dried, the surface can be finished. This involves sanding the surface to remove any rough spots and ensure a smooth finish. The surface can then be painted, wallpapered, or tiled, depending on the desired finish.

  • Clean Up

After the plastering is complete, it is essential to clean up the work area. Any excess plaster should be removed, and the tools used for plastering should be cleaned. This will ensure that the tools remain in good condition and are ready for use the next time.

In summary, gypsum plastering is a widely used material in construction for its excellent fire resistance, soundproofing properties, and ease of application. The operation procedure of gypsum plastering involves preparing the surface, applying a primer, mixing the plaster, applying the plaster in two or three coats, finishing the surface, and cleaning up the work area. By following these steps, a smooth and durable finish can be achieved. From intricate ceiling designs to modern wall partitions, gypsum work in Qatar has come a long way and is constantly evolving to meet the changing needs and preferences of the customers.
