Tile Adhesive

Estimate thinset or adhesive bags for a tile job.

About Tile Adhesive

The pounds of adhesive per square foot come from the bag coverage, and total weight is then divided back into whole bags. Notched trowel size changes coverage, so knowing the per-bag yield keeps you from running out mid-floor.

Formula

Tile Adhesive

Bags = area x (bag weight / coverage) / bag weight

coverage per bag
Square feet one bag spreads at the planned trowel size

Assumptions and limits

  • The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
