Sanding Time
Estimate how long it takes to sand a surface.
About Sanding Time
Total sanding time is the surface area times the passes and the per-square-foot rate, then divided among workers and converted to hours. Sanding is tedious and slow, so a realistic time estimate helps schedule a drywall or refinishing job.
Formula
Sanding Time
Hours = area x passes x minutes per sq ft / workers / 60
- passes
- Number of sanding passes over the surface

Assumptions and limits
- The result is derived only from the 4 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.
