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.
What You Need
- Pressure washer that delivers a minimum of 1,500 PSI at 3.0 gallons per minute (GPM)
- Pressure washer sandblast kit—the kit Paul uses in the video includes a sandblast attachment, 20′ hose and sand probe
- Dry sandblast media
- Container for media
- Protective equipment including a face mask, respirator, ear protection, gloves and appropriate attire
