How to Use the Mapei Grout Calculator
- Enter tile dimensions (in millimeters): Length and Width (e.g., 300 x 300 mm).
- Enter joint dimensions (in millimeters): Joint Width and Joint Depth (e.g., 3 mm and 6 mm).
- Enter the total area to be tiled (in square meters, e.g., 10 m²).
- Click "Calculate Grout".
- Read the result: The calculator shows the total grout needed in kilograms and the number of 1 kg bags required. A formula breakdown is also provided.
Important Notes:
- All inputs must be positive numbers. Use metric units (mm for dimensions, m² for area).
- The calculator assumes a grout density of 1.5 g/cm³.
- Results are rounded up to the nearest whole bag.
