sand blasting media (how much do i need)

I will be sand blasting and coating my frame and fender wells this weekend and need to know how much media I will need unless I can get away with degreasing and wirewheeling rust and putting a primer sealer over it?

There is no real answer to your question.

If your frame and fender wells are really rusty, you will go thru more blasting media then if
they were rust free.

You will go thru more media if you move your blaster slowly, and you will go thru less
if you move it quickly.

You will go thru more or less depending on the type of media you use, such as a
coarser or finer media.

You will go thru more media if you are working outside, in the wind, then you would
if you were working in an enclosed space, like a garage, where there is no wind.

Some media can be sifted, and reused if its not too contaminated. So it would
depend on how greasy, dirty and how dry your parts are that you want to blast
as to whether or not you can re-use it.

These are questions only you can answer.

What you should do is go to a website that sells the type of media you want to use,
and look up their charts.

They will give you a very general idea of how much of each type of media is
used for each type of material you want to remove, ie paint, rust, ext...

A good rule of thumb is to buy at least 20 percent more than you think you will

This way, you won't have to stop to order more if you run out during the process.

Good luck. Blasting your parts will remove WAY MORE paint and rust than a wire
brush. Not only that, but it will remove it from EVERY nook and cranny that a
wire brush just can't get to.

And the results will come out way better too!

Media amount

I just finished sandblasting my frame and used 100 lbs of blasting sand. I did the frame, motor, springs, and axles. Think it was like 15$. The only part I couldn't get was directly under axles, since I still have the motor in, but will address later.

Do note that I used a commercial air compressor that u can rent from most rental places. I would highly recommend this, it will save u aggravation, time, and will be able to go nonstop. Bout 8 hrs total time, and when ur done u have a air pressure that's able to actually blow the sand out of the frame. I was really surprised at how much it put out with just opening a ball valve, I mean hold on TIGHTLY.... Nozzle was hot to touch when I was done

I wrapped a ez-up with painters plastic and on the ground, and was able to recycle 5 gallon bucket full, though I didn't use it

im doing it outside with my great grand fathers blaster he gave me. there isnt too much rust on the frame and still has the factory black paint on most areas. Im using duplicolor rust fix, undercoating for the frame and bed armor for the wheel wells. Should I put a primer sealer on the frame or just undercoat.

Vague question.
How many cfm's does the compressor put out?
How many cfm's is the blast nozzle rated for?
Is the blast nozzle new or wore out?
What type/size grit?
As others said, how rusty/greasy?
Do you want a white blast for a good zinc primer or a mediocre blast for like a clean sweep for a basic primer?
I used to professionally blast/paint ships, oil rigs, trailers and heavy equipment. Cost/amount of sand is immaterial as it is cheap.
