It means you have 30 min working time (half hour) at room temp (70 F I
think). Check the records for exact details but generally the working
time will also change very significantly for colder or hotter
temperature. Something like double at 60F or half at 80F. Generally we
like to use the B-2 product for 2 hours nominal time. That stuff takes
at least half a day to set up in my cool basement but is very quick
outside on a hot day.
