Grout

How many kg to grout the tiles.

How we calculate it

What you enter

  • Area (m²)
  • Tile length (mm)
  • Tile width (mm)
  • Tile thickness (mm)
  • Joint width (mm)

Formula

kg/m² = (Tile length + Tile width) ÷ (Tile length × Tile width) × Tile thickness × Joint width × 1.8
kilograms = kg/m² × Area

Example

The default values from the form, run through the same engine:

To buy
3.2 kg

What to watch out for

Grout usage rises with joint width and tile thickness, and falls with tile size. Large porcelain on a thin joint needs very little.
