    Q&As

    Q: Will this take auto paint off of metal

    4 days ago
    1 Answer
    • A: Yes, the Black Diamond Abrasive products are designed to remove paint and rust from steel surfaces. The Medium Blend is more aggressive and is best for removal of heavy coatings and rust. The Fine Blend is likely more suitable for your application and we always recommend testing a small area first to be sure.

    Q: Does this sand have iron in it

    2 months ago
    1 Answer
    • A: Hello, Black Diamond Medium Blasting Abrasives do contain iron because they are made from coal slag, which naturally includes iron oxides. This makes the product excellent for heavy-duty rust removal on steel, though it should be avoided on aluminum or stainless steel to prevent surface contamination.

      A: The size of the crystals ranges mostly from 1.5 to 0.4 mm. This medium grade is a 16/30 material, though a small percentage of more coarse or fine material may also be present in the blend.

    2 months ago
    1 Answer
    • A: Its possible but it could be too aggressive for this application. There are several variables including the hardness/finish of the tile, the equipment being used for blasting and the nozzle pressure. We recommend testing a small area first if possible.

    Great aquarium substrate!

    10 years ago
    Looking for some shiny black sand for your aquarium? Look no further because this stuff (med) is great in an aquarium. Super cheap compared to any black "aquarium sand". Just put some in a bucket and run a hose though it until the water is clear. Additionally you can add a few drops of dish soap at the beginning to remove any greasy residues. one year later and all my plants and fish are happy. Perfectly safe even for sensitive bottom dwellers such as Cory cats.

    I bought this to use with a new media blaster. I have 1/8" nozzles, as my compressor isn't that big. The medium size will not pass through a 1/8" nozzle. I thought I was purchasing the fine. I think the media is fine for outdoor work, but watch your size...

    Very good price, but it doesn’t flow as good as sand for blasting. Can’t use sand anymore due to health hazard.

    Black label/tank substrate-

    4 months ago
    This is my second purchase of this for substrate in a 55 gallon aquarium! So affordable, I fill a 5 gallon bucket about 4 inches from the top and let water rinse throughout until water is clear and no longer showing any film on top, then I place it into the tank with a scoop. 1 bag was enough and it looks so good!

    Yes, I recommend this product.

    Fine/red= sandblast; Medium/black= tank substrate

    4 months ago
    Seen reviews on this for tanks after using it in our gunsmithing shop for sandblasting firearms prior to painting. We use the red fine grit for the sandblaster and the black label medium grit for the tank substrate. Both work great and are SOOOOO MUCH MORE AFFORDABLE than other options. Definitely more bang for your buck in both scenarios!

    Yes, I recommend this product.
