REDWUD CONSTRUCTION INTERIORS

❌ Avoid These for Plastering: • Coarse sand (used for concrete): Too rough for smooth finishes. • Desert sand: Too fine and smooth; poor binding. • Sea sand: Contains salt which can lead to corrosion and poor bonding unless thoroughly washed. • Dirty or clayey sand: Leads to cracks, poor adhesion, and low strength. Tips Before Using Sand: 1. Sieve the sand to remove larger particles. 2. Wash if needed to remove clay, silt, or salt. 3. Do a “silt content test” – silt should be less than 6% for plastering sand. 4. Follow the plaster mix ratio: Commonly 1:4 or 1:6 (cement:sand) depending on application.
