Tile grout quantity
Estimate grout from tile modules, joint depth, and wet density.
How this works
Joint fraction = 1 − tile area/module area. Liters = tiled m² × joint depth mm × joint fraction.
Example
Using the example inputs, grout with allowance is 3.121106 kg.
- Tiled area
- 10 m²
- Tile length
- 300 mm
- Tile width
- 300 mm
- Joint width
- 3 mm
- Filled joint depth
- 8 mm
- Wet grout density
- 1.8 kg/L
- Extra allowance
- 10 %
- Grout with allowance
- 3.121106 kg
Scope and assumptions
Ideal rectangular grid, full-depth joints. Product coverage and cleaning losses may differ.
