I'm trying to transition into commercial painting specializing in the horse farms around central KY and my first job involves taking down 11 heavy metal powder coated horse stall doors that have gotten somewhat rusted, sandblasting them then painting. I've done a lot of stuff but sandblasting isn't one of them. So I'm wondering just how does someone like me go about doing something like this. Do equipment rental places carry stuff like this? Other than handling the doors which I've got help for, is this blasting job something your average motivated joe can tackle?

Also, was wondering what'd be the best environment to get it done. The doors are installed in an all wood stable, and although a horse stall sounds like the ideal place to lean these gates up and blast away, I'd be afraid the wood wall behind it would disintegrate. There's another stable nearby that's made of cinder block which I imagine would make for a better staging area. These stalls are about 13 ft square which seems ideal for keeping the all the sand contained. I'm sure the wall would need repainting after everything was finished, but would a cinder block wall generally stand up to being hit with lots of sand?

Rubber stands up to sandblasting probably as good as anything. It's still used for making sandblasting stencils today. You could buy it in rolls and fabricate wall covers to hang on the stall walls. With a portable rack to hang the doors horizontally it's possible you could blast in wooden stalls without damaging them.

Recovery of the blasting medium would be another concern.

Check in your area for dustless blasting companies. Some have trailer mounted equipment and will come to you. The dustless system also creates a lot less mess.

I have a distress trailer mounted unit that uses baking soda, clean up on this is as easy as washing it down with a hose.
I'm guessing these doors are heavy enough that heat and warping from the blasting won't be an issue.
