A corner guard is used while plastering a wall to protect the sharp edges of the corners from damage, ensuring a clean, smooth finish and preventing chips or cracks that can occur from impacts or wear and tear, particularly in high-traffic areas; essentially, it acts as a reinforcement to the vulnerable corner points of the wall. Key points about using a corner guard: Prevents damage: The guard absorbs impacts and prevents chipping, scratching, or tearing of the plaster at the corners, which are prone to damage due to everyday activities like moving furniture or accidental bumps. Improves aesthetics: By keeping the corners clean and intact, a corner guard enhances the overall appearance of the plastered wall. Durability: Corner guards are often made from sturdy materials like plastic or metal, which can withstand regular wear and tear. Suitable for high-traffic areas: In places like hallways, hospitals, or schools where walls experience more frequent impacts, corner guards are particularly important.
