Coverage per bottle per coat

Enter this project assumption in ft². The current imperial default is 200 ft².

Joint and waste allowance

Enter this project assumption in %. The current imperial default is 15 %. Minimum: 0. Maximum: 50.

Bottle volume

Enter this project assumption in fl oz. The current imperial default is 24 fl oz.

Price per bottle

Methodology

Transparent calculation

BuildMeter converts every input to a consistent internal unit, applies the selected allowance, and rounds products up to whole purchasable units.

Coat-equivalent area = tiled area × coats × allowance factor. Bottles are rounded up from product coverage.

FAQ

Tile Grout Sealer Calculator questions

Why use tiled area instead of grout-line length?+

Many product labels publish approximate coverage by tiled area. A grout-line method is more detailed when joint geometry is known.

Do all grout products require sealing?+

No. Some grout systems are designed not to need a penetrating sealer.

Can sealer damage tile?+

Residue can haze some surfaces. Test the application and follow cleanup instructions.
