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.

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.

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.

Stainless steel should typically be re-passivated after blasting. After that, it can be left as long as the surface isn't contaminated.
