I'm a BELIEVER as well BUT,
It basically comes down to "what" you can get LOCALLY as well.
I used sand because IT was ALL I could get without paying an arm & leg for SHIPPING.
Not that THAT is an excuse but when they charge $6.00 for 50# but $25.00 a BAG shipping,THAT hurts.
Yeah I know,Choking in your own spit ain't pretty either.
No silica in the slag at all but like ANYTHING you blast with,
USE A GOOD RESPIRATOR.
No "dust" mask but a fresh air or quality cartridge type. Regardless of the media.

|shine||you wont be sorry. now that we have what we're blasting with covered lets talk about "what" your blasting off. remember , that old paint is lead based and rust dust s very bad also. pay attention to where the cloud is going and keep your protection on until you've cleaned up. you're also going to notice less surface rust than you get with sand.|

Shine, if it makes you feel any better, you've convinced me. I have bought black diamond from Northern tool for 7 bucks a bag. I even got three bags at half price that were torn open. You're right, the SLIGHT difference in cost just ain't worth it.

|bitor||does coal media have any quartz at all?|

|shine||it is scary red. i just pray that my stupidity of youth is not going to come back on me. i too have done it. but when setting up the blasting business i did my homework. what i found was terrifying. i know some of you guys get tired of my preaching every time this comes up but get use to it. if i can steer one person away from this crap it will be worth it. every time someone recommends this stuff i will hit the pulpit. there are approx 100 different medias available for blasting and sand ain't one of them . remember 5% quartz or less is the rule.|

Shine, After having worked around the mining industry I have seen far too much of what silica can do to a person and what is so shocking is how little it takes to do it! Even though I was a vendor I still had to sit through the safety training before I could work at some mines and some of the things we learned about silica was worrisome to say the least. When you consider that the dust they were dealing with contained only a fraction of the free silica that will be in blasting sand it really gets scary. I have used play sand quite a bit and I have recommended it to others (even in this thread ) but I took extra care to use the proper protection and always warned about the hazards. I think I am going to take a different stance from now on because the risks are too high and I know that too many people will use that stuff with improper or no protection but the biggest thing is what you said about the "collateral damage". Even dusting one's cloths off after working with sand can stir up dangerous amounts of silica and the area around the operation will be dangerous until the dust is gone, but I suppose you know all this already. I have heard the tired old arguments about some "old timer" who has done it for years with no protection and no problems but to those that think this is making too much out of the hazards better think again since even one heavy exposure can do damage that may not show up immediately.
As you have said repeatably, sand kills. I will not recommend it to anyone anymore.

I would take you to court because you are smoking that cigar in your picture and pollute my air over here in Greece and also rise global temperature and bears cannot sleep.

|bitor||no more play sand for me, too much dust and I cannot see anything.|
|12-25-2006 08:14 AM|
|shine||for those of you doing your blasting at home or in the yard. remember this , if you lived by me i would take you to court for endangering the lives of me and my family. play sand dust from blasting is a killer. think of your kids and others if not yourself. every time you recycle it the dust gets finner and more dangerous. i do blasting as a business and the industry as a whole is trying to get rid of sandblasting all together. there are much safer medias to use . i find it disturbing that people recommend this stuff without doing their research. the safe rule in the industry is 5% quartz or less. if 10 bucks a bag is too much you are in the wrong hobby. take care of your lungs....... their the only ones you got|

TSC play sand. $5.00 a bag and finer than Black Beauty and cheaper. I fought al day with a sandblaster that kept clogging up. New tips, the sand was coarse enough that it would lock up inside the tip after a few minutes. As far as contamination, a powder coating facility a few towns over does not like to do anything that an owner has prepped 100% due to contamination with the wrong sand, etc. All they use is aluminum oxide to blast parts.

|12-23-2006 01:14 PM|
|KernCountyKid||I recycled some of the black beauty that I used (@ 10$ a bag I had to!) I would just say be careful what you recycle. Media used on certain areas like the frame just shouldn't be reused at all. It's not worth the risk of the contamination.|

|oldred||Bee, That warning about contaminating the sand/media with sealer, oil, grease and undercoating is one that is not mentioned enough. Some years ago I recycled some sand that I had used to blast the underside with after scraping as much old undercoating off as I could but the tar (or whatever that crap is) wound up embedded in the metal surface where it caused some real headaches. It is not as simple as wiping it down afterword because the rough surface makes it a bear to remove and if you don't get it ALL-|
