Wet Sandblasting: Clean, Fast and Dust-Free

High-volume air compressors and sandblasting equipment are significant investments, especially if you are planning to use a sandblaster occasionally or for only one project.

A wet sandblasting kit provides an alternative to traditional sandblasting. They are great at removing rust, paint, stains or any unwanted material. These kits are relatively inexpensive and very easy-to-use. Plus, they don’t create dust like a traditional sandblaster.

How Easy Is It?

  • Place the sand probe in a bucket of sandblast media, keeping the probe’s air intake above the sand
  • Connect the sandblaster attachment to your pressure washer wand
  • Start the pressure washer, with the lance pointed away from your body and project

Most models (including the one shown in the video) feature a male quick coupler that fits in place of the nozzle. Once the pressure washer is running, the velocity of the water draws dry sand through the hose and into the stream. The combination of high-pressure water and sandblast media quickly strips away unwanted paint or rust.

“I love using a pressure washer sandblaster because it is effective and efficient,” says Paul Morgan, Assistant Manager at KMS in Coquitlam. “I sandblasted a Morris Minor inside and out, and used only seven bags of sand.”

Another benefit of wet sandblasting is that your work surface stays cool, and this can help prevent the metal warping that sometimes accompanies traditional sandblasting methods.

  1. My brother and his wife recently decided that they want to repaint the outside of their home. You mentioned that a wet sandblasting kit provides an alternative to traditional sandblasting and they are great at removing rust, paint, stains, or any unwanted material. I didn’t realize this technique was available. Do most restoration companies offer this option? It seems that this could be beneficial for them.

  2. KMS, good afternoon. Wanted to know your recommendation on the use of this product on aluminum stern drives on a boat. I want to tear mine boot legs down to the bare aluminum and start from scratch but am worried that this might pit the metal…any recommendations are already highly appreciated!
    Gratefully,

    • Hi Luis, Thank you for your comment. You could try ground walnut shells. Walnut shell is less abrasive than glass bead or aluminum oxide. Plus it’s biodegradable!
      Thanks!

  3. yes,Im interested in purchasing one of your wet blast kits. My question is most pressure washers on the market are only 2.5 gpm even on machines with 3500 psi. will the kit work with with unit only producing 2.5 gpm. thanks kevin

    • Hi Roger,

      Thank you for reading and commenting. You can find the price of the wet sandblasting kit here and you’ll need a pressure washer that delivers a minimum of 2,000 psi at 3.5 gallons per minute.

  4. Hi there,

    Can glass beads be used without issues with this kit?? Meaning will the tip of the blasting hose last a while?

    Thank you

    • Hi Martin,

      Yes, you can use glass bead, but it’s more expensive than crushed glass. Unless you dry it after use, the media can be used only once with a wet sandblaster. You can find sandblast media here.

      The ceramic tip is really durable and it should last a long time. In the past 15 years we’ve ordered only one or two replacements. As for the hose, it too is pretty rugged. When the time comes to replace it, you can find similar hose at most hardware stores.

      Hope that helps!

  5. So, I have a pressure washer that’s 3200psi but only 2.5 gpm. My Dad’s Pressure washer is 3 gpm but only 2500psi will either of them work with your Wet Sandblaster Kit?

      • Sure, but will they work well? What’s the consequence of using machines below the recommended specs? How does lower GPM and/or HP effect performance?

        • Hi Douglas,

          Thanks for following up. We checked with the manufacturer and the minimum volume for the 9001-9 sandblaster kit is 3.0 GPM.
