Rated 1 out of 5 by from Don't bother My local tsc ran out of fine and I needed to finish blasting a frame so I figured it would do the trick. I spent 1% of time blasting and the other 99% unclogging my nozzle. The fine works great but this was a nightmare to use. Don't buy it.

Rated 5 out of 5 by from Using for Aquarium Substrate Great product to use as "sand" as my aquarium substrate. Washed it thoroughly and it looks great! Plus you can't beat the price compared to sand sold specifically for aquariums.

Rated 1 out of 5 by from Don't buy this for blasting media I should have listened to the guy who wrote the review saying he could not get it to come out of his blaster nozzle because of the irregular long cone shaped pieces. Nozzle had a hole almost 3/16 and it still would not come out. This is a complete waste of money for the intended purpose. And no they have not changed it like they commented to his review. As far as trying to take it back it would cost me more than it is worth.

I see on the bad the product needs to remain dry, what happens to it if it gets wet?

Asked by: MichaelD78
If the bag or product gets wet it will clump together and harden resulting in it being unusable.

Asked by: Joseph Pa
The Black Diamond product has been used in this application in the past by other customers. We are not aware of the specific mix ratios that were utilized in order to achieve the desired result. We would recommend testing a small area and making adjustments as needed.

Asked by: JR BUSTOS
30/60 grit sandpaper is considered course, but this medium grit abrasive media will work well for your purposes. This product will cut through paint and rust quite fast, and a more course product is not necessary in most cases.
