Accurate job planning starts with knowing how long your blasting will take. Factors like nozzle size, air pressure, abrasive type, and desired surface profile all influence production rates—and guessing can lead to costly scheduling errors. Our Blast Time Calculator estimates the time required to blast a specific surface area under your chosen conditions, helping you plan projects, allocate labor, and forecast equipment usage more accurately. By using this tool, you can set realistic timelines, reduce downtime, and keep projects on budget from start to finish.

Job Inputs
If you measured in square meters, select “sq m”.
Base production rates assume near-white metal on steel at ~100 PSI.
Productivity drops as pressure falls. Interpolates from ~50→100 PSI data.
Two operators roughly double the area/hour (all else equal).
%
Accounts for technique, steady pace, and typical short pauses.
%
Covers pot refills, staging, minor delays, weather, etc.
