wallsand

Wallsand is a construction sand used primarily for wall-related applications. It is selected for its graded particle size and cleanliness, making it suitable for mortar, plaster, and renders that form the exterior or interior skin of a structure.

Composition and grading: Wallsand is largely silica-based, consisting of quartz grains of varied shapes. It is typically washed and screened to remove clay, silt, and organic material, with a grain-size distribution matched to mortar or plaster specifications.

Applications: In masonry, wallsand is mixed with cement (and sometimes lime) to produce mortars that bond bricks or blocks. It is also used in plastering and rendering to create smooth, durable wall finishes.

Production and standards: Sourced from natural deposits such as rivers, beaches, or crushed rock, wallsand is sold in general-purpose or plastering grades. Standards assess fineness, silt and clay content, cleanliness, and moisture to ensure workability and curing performance.

Safety and handling: Dust from silica-containing sands can pose respiratory hazards, so handling should include appropriate dust control, PPE, and compliance with occupational health guidelines. Proper storage guards against contamination and moisture-induced clumping.
