Achieving a Perfect Finish with Cement Plastering
Plastering with cement is the most prevalent method for achieving a flawless finish, smooth surfaces, and robust building walls in any construction endeavor. This process involves applying a thin layer of cement mortar, an adhesive material, to walls and roofs. Various forms of plastering exist, including lime, gypsum, cement, and clay plastering.
Cement stands as a critical component and a ubiquitous material in real estate construction projects. Among its many applications, plastering houses is a prominent one. The type of cement employed directly impacts the lifespan of a building, emphasizing the importance of selecting the right cement for optimal plastering results.
Choosing the Best Plastering Cement
Portland Pozzolana Cement (PPC) and Ordinary Portland Cement (OPC) represent the two most frequently used cement grades for plastering. While the specific cement type can vary based on the building's needs, PPC cement generally holds the superior position due to its numerous advantages. Its enhanced water resistance protects the structure from cracks and fractures. Although softer than OPC cement, PPC provides an enhanced finish. Another critical factor influencing plastering outcomes is the cement plastering ratio. Building types influence plaster requirements. Typically, if plaster thickness surpasses 15 mm, two coats are applied. When plastering a home's exterior, masonry or white cement can be used for decorative purposes. Ultimately, the optimal plastering cement depends on the specific project requirements.
Understanding Various Cement Grades
Varying cement grades represent differences in the mix's strength, highlighting the necessity for distinct grades. The market offers three primary cement grades: Grade 33 (IS: 269), Grade 43 (IS:8112), and Grade 53 (IS: 12, 269). Grade 33 cement is commonly used for plastering while Grade 43 finds applications in flooring, precast elements, and plastering as well.
Cement mortar plays another essential role in achieving a smooth plaster finish. Composed of sand, cement, and water, mortar's strength depends on the cement-to-sand ratio. Precise wall plastering relies heavily on cement mortar. Beyond plaster, cement mortar also constitutes masonry blocks like bricks, plaster walls, and slabs.
