Why use Wet Blasting Systems?

Wet abrasive blasting reduces the dust generated by dry blasting but can still remove coatings and corrosion residue and create a clean, profiled surface.

The advantage of wet blasting technologies is the ability to blast without dust when containment is too costly or not viable.

You have precise control of the air, grit, and water flow to lock in optimal blasting performance with efficient grit and water consumption. Once optimal flow parameters are set, switching between normal blasting settings and lower air pressure for wash down and blow off is consistent, fast, and easy.

Blasting pressures are able to be set between 10 and 150 psi.

Common issues with Wet Blasting Systems

Wet blasting systems from BlastOne use mist blasting technology, which injects water into the metering valve after the abrasive has been metered. Many of the alternative systems use slurry blasting which

Mist Blast technology overcomes two common problems of other wet blast technologies: inadequate water flow control and inadequate abrasive flow control. Changing grit size accentuates this problem. With wet abrasive in the pot i.e., slurry blasting, it is difficult to control the water and abrasive flow. This is because the feed water needs pressurizing to push the abrasive out. The larger the abrasive particle size, the larger the problem is. The coarser the abrasive, the larger the gaps between the abrasive particles, i.e., the abrasive holds more water. This requires a large amount of water to get flow. Typically, when using a Slurry Blasting system, a fine abrasive is used to give more control of the abrasive and water volumes.

Important considerations when choosing the right Wet Blasting Systems

The most important consideration when selecting a wet blast is which technology to use, slurry blasting or mist blasting. Mist blasting has some distinct advantages.

Mist Blaster technology controls abrasive flow better and reduces water consumption. The two key reasons you want to reduce water consumption are:

  • Wet abrasive is always harder to dispose of than dry.
  • Large volumes of water create a liquid waste disposal issue, which can be more complex than dry waste disposal.

With Mist Blast technology, you can use less than one pint of water and still get a high production abrasive blasting rate with a 90% or greater dust reduction.

Frequently Asked Questions

  • Do I need to use a rust inhibitor when wet blasting?

    Yes, introducing water to an abrasive blasting stream recreates the issue that probably prompted the blasting in the first place: flash rusting. Blasters can combat flash rust by introducing a rust inhibitor into the water. Dosing for this is typically 50:1. Typically, a surface will flash rust within 30 minutes if it gets water on it. Adding a rust inhibitor to your wet blast stream will hold the blast for up to 8 hours.
  • What other additives can I use with wet blasting?

    Mist Blasters also allow the injection of soluble salt removers into the wet blast stream. Abrasive blasting does not remove soluble salts, present in maritime or some industrial environments, and must be removed by washing down. Usually with a proprietary fluid added to the wash water. If dry blasting, this needs to be done as two separate processes. However, wet blasting allows the fluid to be added to the blasting stream, combining the two tasks. Always check with your coatings supplier before using additive to ensure that using such products conforms to their performance guarantees.
  • Do the same hose sizing principles apply to wet blasting as dry blasting?

    • An important rule of thumb when using a Mist Blaster is that the blast hoses should be a maximum of 3 times the diameter of the blast nozzle. If you exceed that ratio, the abrasive tends to drop out and causing “slugging” of abrasive in the blast hose. When dry blasting, making the blast hose larger reduces pressure loss. For example, if blasting with a ½” nozzle, use a maximum 1½” diameter blast hose. If you use a ⅜” nozzle and a 1½ hose, abrasive will start dropping out and start “slugging” because the water/abrasive mix will move too slowly through the hose to be carried effectively by the airstream.
    • If blasting vertically with a Mist Blast or a Wet Blast system, water flowing back down the hose internally. The longer the vertical run of hose, the bigger the risk. The problem with this happening is that water flowing backwards down the hose back risks getting into the abrasive metering valve. If blasting vertically, have a 25’/ 8m or longer section of hose running horizontal before you send your hose up from the blast pot. This ensures that any water running backward down the blast hose will sit in the horizontal length of hose rather than going back to the abrasive metering valve. The operator can blow out this retained water out when next starting next.
