Shot blasters

2380 7
IT's been a long time since I've used a shot blaster in the ship yard....
I'm pricing a job for a metal deck walk way, out side 7' x 260' long and it's over water.
Deck it solid plate.... Has rust and non skid flaking off..
Shot blasting I feel is the only way to get it done.

I'm going to rent, and only place is sunbelt rentals that has them.

So, I know they use them a lot for concrete floors

I need to know if anyone's used or has one
And what I'll need to use them
It say 220v for the machine but will I need to rent a diesel gen to run the driver and air vac ?
Steel shot or steel grit ( sharp) ?

Give me some Insite to help out guys

Steel grit will probably get you in trouble with the rental company as it really tears them up bad. What you'll need to run it will depend on the size that you get. Sunbelt should have everything that you'll need to run it though. I'd get with them first and then go by and look at everything before I'd rent.
Thanks Benny
Few pictures of the job

Haven't bid yet, want sll my ducks in a row first lol


I have used them and yes sunbelt has them. Try and locate a propane powered unit for that job. Not sure of total access in and out but with out seeing the area to enter it might be difficult to access. They usually have a dust containment all in one. It's a drive on unit. Not cheap to rent for a day either nor is the steel shot. I do however think you are in the right direction for that job.
Good luck Jim!

After looking at your picture again I think you might want to use a sit on scraper unit ,the non skid might be too thick for a shot blast machine
