Gypsum plaster powder is a popular building material widely used in Malaysia for its versatile and cost-effective properties. However, like any construction material, it comes with its own set of challenges that need to be addressed for successful application and long-lasting results.

One common challenge faced when using gypsum plaster powder in Malaysia is poor adhesion to the wall surface. This can be attributed to various factors, such as high humidity levels, uneven wall surfaces, or inadequate surface preparation. In humid environments like Malaysia, moisture can accumulate on the walls, affecting the drying process and compromising the adhesion of the plaster. Similarly, if the wall surface is uneven or contaminated with dust, it becomes difficult for the plaster to bond effectively.

To overcome this challenge, proper surface preparation is crucial. The walls should be cleaned thoroughly, removing any dust, dirt, or loose debris. Additionally, it is recommended to apply a suitable primer to improve adhesion and create a uniform surface for plaster application. This will ensure better bonding and durability of the gypsum plaster.

Another challenge faced when using gypsum plaster powder is cracking or shrinking of the plaster after application. This issue can arise due to factors such as improper mixing ratios, inadequate curing time, or excessive thickness of the plaster layer. Cracking not only affects the aesthetic appeal of the plaster but also reduces its stability and durability.

To address this challenge, it is important to follow the manufacturer's instructions regarding mixing ratios and curing time. The gypsum plaster powder should be mixed with water in the correct proportions to achieve the desired consistency. It is also essential to allow sufficient time for the plaster to cure and dry properly before any further finishing or painting is done. Furthermore, applying the right thickness of plaster in multiple layers instead of a thick single layer can help minimize the risk of cracking.

One more common challenge is surface blemishes or uneven textures in the plastered walls. These imperfections can be caused by inconsistent application techniques, improper tools, or inadequate workmanship. Uneven textures or blemishes can make the walls look unappealing and require additional efforts for remediation.

To overcome this challenge, it is vital to ensure proper training and skill development of the workers involved in the plastering process. Using the right tools, such as trowels and floats, is crucial for achieving a smooth and even finish. Proper application techniques, such as spreading and flattening the plaster evenly, can also help in minimizing surface blemishes.

In conclusion, gypsum plaster powder is a widely used building material in Malaysia due to its versatility and cost-effectiveness. However, it is essential to address the common challenges that arise during its application to ensure long-lasting and aesthetically pleasing results. By ensuring proper surface preparation, following correct mixing ratios, allowing sufficient curing time, and using appropriate application techniques, these challenges can be effectively tackled, leading to successful plastering projects in Malaysia.
