Besto Ready-Mix Plaster is a pre-blended material composed of high-quality Ordinary Portland Cement, graded sand, and specialized additives. These specifications are in accordance with the relevant Bureau of Indian Standards (BIS) codes to ensure quality, durability, and performance in construction applications.
Ready-mix plaster offers a streamlined and quality-controlled alternative to traditional on-site plaster mixing, providing a consistent and high-quality finish for both internal and external surfaces.
This specification covers the requirements for ready-mix plaster used for plastering walls, ceilings, and other concrete surfaces. The material is designed for application on various substrates, including brickwork, concrete blockwork, and AAC blockwork.
Store in a dry, covered place away from moisture to prevent lump formation. The shelf life is generally around 12 months from the date of manufacture when stored under appropriate conditions.
