What Is Dustless Blasting?

Dustless blasting, also known as wet blasting or slurry blasting, is a blasting method that uses a mix of water and abrasive in the blast pot. This mix of media and water makes for a more precise blast; this is because when water is added, the energy and mass the machine produces is increased while also eliminating dust. Dustless blasting can use any media that isn’t water-soluble. However, the most common media used in dustless blasting is crushed glass because it is cost effective, clean, economically friendly and can be used for a variety of jobs.

Dustless Blasting and Metal

Metal surfaces can be particularly sensitive to some blasting practices. Often, metal heats up due to friction from blasting and warps as a result. However, dustless blasting prevents this from happening. When water is added to the abrasive, the friction and heat are reduced, protecting the metal from any kind of warping. In fact, in most cases the temperature of the surface being blasted is reduced by about 10 degrees. When using dustless blasting on metal, however, a rust inhibitor must be added in order to avoid flash rusting after the surface is blasted with wet abrasive. For example, HoldTight 102 is an additive that is combined with the water in the dustless blaster; this additive not only prevents flash rusting but also removes chlorides and other salts and contaminants very effectively.

Uses and Benefits of Dustless Blasting

Dustless blasting has many uses and benefits. Not only is dustless blasting faster, it also produces 90% less dust, does not warp metal, is safe for workers, requires minimal containment and leaves a paint ready surface. Beyond this, dustless blasting uses less media to do more work. Dustless blasting is very beneficial when blasting on job sites where other workers are present. Due to low dust, other trades are able to stay on their tasks without being disturbed by open-air dust. However, dustless blasting cannot be used in temperatures below 32 degrees and is not recommended for indoor use, such as mold remediation or fire restoration jobs.

Why Dustless Blasting

  • Faster – The Dustless Blaster can strip a car in under 2 hours.
  • Minimal Dust – The abrasive gets trapped in water and grounded, eliminating the plume of dust.
  • No Warping –  The water prevents friction and won’t warp thin metal like sandblasting will.
  • Eco-friendly – Recycled bottle glass contains no free silica, the leading cause of silicosis.
  • Less Containment Needed – In most cases, expensive, time-consuming containment does not need to be set up.
  • Leaves a Paint Ready Surface – The rust inhibitor decontaminates the metal leaving a clean, chloride free paint ready surface.
