Plaster Ratio Guide
Choosing the correct ratio of Cement to Sand is vital for the strength and finish of the wall.
- 1:3 – Very rich mix, used for repair works or external weather-prone areas.
- 1:4 – Standard mix for ceilings and external walls.
- 1:5 – Commonly used for internal brick walls.
- 1:6 – Economical mix for internal walls with good quality bricks.
Formula Explained
Volume = Area × Thickness
Dry Volume = Wet Volume × 1.33 (Adding 33% for bulkage & wastage)
Cement = (Ratio Part / Total Ratio) × Dry Volume × 1440 kg/m³
Dry Volume = Wet Volume × 1.33 (Adding 33% for bulkage & wastage)
Cement = (Ratio Part / Total Ratio) × Dry Volume × 1440 kg/m³
