Plastering Sand
Overview:
Plastering sand is a fine-grain sand specifically used for plastering walls and ceilings. It provides a smooth and durable finish, ensuring strong adhesion with cement and other binding materials. Sourced from riverbeds or crushed aggregates, this sand is free from impurities, making it ideal for construction and finishing applications.
