How many pounds of sand does it require to sandblast 1 sq ft of metal surface?

More information is needed to answer this question. There are too many variables:
* How much compressed air do you have available (volume - cfm)? * What type of blast system are you using to blast? Siphon? Pressure? * What size blast nozzle will you be using? * What size/type of abrasive* will you be using?
* Hopefully you will not be using silica sand. The health hazards (silicosis) associated with breathing in the dust generated in the blasting process is not worth the cost savings or convenience in using that abrasive. Dust masks, air fed hoods or air fed helmets help a little bit but DO NOT 100% protect the person blasting.

First off, you will not want to paint the inside of your walk-in due to food safety issues. To paint the outside you will need to either sandblast the metal or use a self etching primer. Normal paint will run on a smooth metal surface so you need to give the paint places to cling to. And with painting a walk-in there is a good chance the paint will not properly adhere, so be prepared to repaint or deal with chipping.
