Cement plaster is a mixture of cement, sand, and water used to create a smooth surface on walls and ceilings. It is commonly applied to both interior and exterior surfaces, providing a durable and weather-resistant finish. The plaster hardens as it dries, forming a strong bond with the underlying material. This type of plaster is favored for its versatility and ease of application. It can be used for various purposes, including leveling uneven surfaces and providing a base for paint or wallpaper. Additionally, cement plaster is often used in construction for its fire-resistant properties.
