From Daniel Liu of APC on February 6, 2013:
     No special guideline prescribes such a time window. It can be left there as long as no obvious discoloration is observed. I believe the main purpose for blasting is to obtain the specified profile for the coating application. Thanks.

From Ahmed Abd Ellatif of ENPC on February 28, 2013:
Painting can br delayed 2 to 4 hours, depending on relative humidity.If it is high, the surface will be affected.  We will find shadows, which then require reblasting. 

From Greg Howe of LPRI, LLC on February 8, 2013:
     Follow the product data sheet for the specified coating. This will give you profile and cleanliness requirements. Typically, SSPC-SP 1, solvent cleaning, is required to remove contaminants prior to coating.

From Tom Schwerdt of Texas Department of Transportation on August 30, 2012:
    Stainless steel should typically be re-passivated after blasting. After that, it can be left as long as the surface isn't contaminated.

From anthony meglino1 of asap on August 21, 2012:
It can be left less than 24 hours.
