I know a few of you guys have a lot of experience with blasting pools. I've got a 1950's steel inground pool that I'm going to be blasting in a couple weeks. I'm trying to get a more accurate idea on how much surface area I can expect to be able to clean in a day. I'm not really sure how thick it is, so assume it's thick. I have a 375cfm high pressure compressor with a number 7 nozzle. I'm debating on which media to use. I'm thinking coarse black beauty or maybe coarse alox. I'm more concerned about getting it done faster than the cost of the media. Any thoughts on coverage?

Probably slow either way. Hard to really tell until you get in there on it. Sometimes if it's old and dried out it'll come off fast. On the other hand, if the coating has any life left to it it may just roll off real slow on you. Those can be a pain. Can you put a DFT gage on it to see how thick it is?

I'll see if I can get back over there. I forgot my Guage when I went.

Forget the gauge,. Bring a knife and a scraper and see what is actually going on with it.

I did scrape some and it come off on in the spots where I tried.
