Estimate the amount of grout needed for a tiled area.
For square tiles, the total joint length per square foot is about 24 divided by the tile size in inches. Multiplying by joint width and depth gives grout volume, then weight. Grout is easy to underspecify on first tiling jobs, and running out mid-project stalls progress while the mix stays open only briefly.
Grout Estimate
Grout = joint length x joint width x depth; weight at ~90 lb/cu ft
