How The Calculation Works
Formulas, material coverage assumptions, waste buffers, and rounding standards.
Grout volume depends on tile dimensions: smaller tiles (e.g. 4"x4") require significantly more grout than large-format tiles (12"x24") due to increased joint linear footage.
We compute total joint volume in cubic inches and multiply by dry grout density (~0.060 lbs/cu in) with a 10% cleanup buffer.
