## What is Grout?

Tile grout is a substance that is used to fill in the gaps between the tiles in order to keep dirt and fluids out. When laying tiles, we leave spaces between them to reduce the likelihood of future breaking or lifting off of tiles owing to floor or wall thermal or structural deformation, tile expansion, or tile movement. Grout is a composite substance made up of cement, lime, and water, as well as sand.

### Volume of Grout Formulas

Space covered by grout = 1 – {WL / [(W + s ) (L + s)]}

The volume of the grout = A × d × (space covered by grout)

Here, W = width of a tile, L = length of a tile, s = grout space

A = area of space in inches, d = depth of a grout

### How do you Calculate How Much Grout I Need?

Follow the simple steps listed below to calculate the Grout. They are as such

1. Check the area of total space to be tiled.
2. Check the dimension of a tile.
3. Check the distance between each tile & the grout depth
4. Use the above-mentioned formula to calculate the quantity of required grout.
5. Finally, the obtained value is the quantity of grout required for your space.

### Grout Estimation Examples with Solutions

Example:

We want to tile the room with a total floor space of 150 square feet. Here the measurement of a tile is 6×6 inches. Space between the tiles from all sides will be 0.3 inches & grout depth will be 0.25 inches. Calculate the amount of grout needed to complete the tiling of the whole floor space.

Solution:

Here, area A = 150 square feet = 21600 square inches

W = L = 6 inch,

Grouting space, s = 0.3 inch, d = 0.25 inch

Now , using the formula:

Space covered by grout = 1 - {WL / [(W + s ) (L + s)]}

= 1 – {36 / [(6.3)(6.3)]}

= 1 – {36 / 39.69} = 0.093

Volume of the grout = A× d × (space covered by grout)

= 21600 × 0.25 × 0.093 = 502.2 cubic inches

= 2.17 gallons
