Overview:
Dossary sand is a high-quality type of sand known for its fine texture and excellent purity. It is widely used in construction, plastering, and masonry work due to its smooth consistency and superior bonding properties. This type of sand is often preferred for high-end finishing applications where uniformity and strength are essential.
Why You Should Use It:
- High Purity: Contains minimal impurities, ensuring a smooth finish.
- Excellent Bonding: Enhances adhesion in mortar and plaster applications.
- Uniform Particle Size: Provides consistent texture for superior finishes.
- Multi-Purpose Use: Suitable for concrete, masonry, and rendering.
- Low Shrinkage: Reduces the risk of cracks in plaster and concrete.
