Heavy-Duty Surface Preparation

Larger structures, heavy rust build-up and stubborn old coatings need more than a light clean-up before they're ready for a protective coating to be applied. At JH Protective Coatings, we provide abrasive blasting in Newcastle for commercial and industrial projects that need thorough, efficient surface preparation across large or awkward areas.

We work across structural steel, machinery and equipment, matching the abrasive media and technique to the size and condition of the job in front of us. If your project needs finer surface preparation as well, our sandblasting service can handle the more detailed work alongside abrasive blasting. Call (02) 4953 2274 to discuss your project.

How Abrasive Blasting Works

Abrasive blasting is suited to bigger or more demanding surface preparation jobs. Here's what it typically involves.

  1. We select an abrasive media suited to the surface and the level of rust or coating build-up involved. This helps clear larger areas efficiently without unnecessary rework.
  2. Blasting is carried out in stages across large or complex structures. This keeps the finish consistent from one section to the next.
  3. We monitor surface condition throughout the process to check the right depth of cleaning has been reached. This avoids under-preparation, which can cause coatings to fail early.
  4. Once the surface meets the required standard, it's left ready for priming or protective coating. This gives the finished job the best chance of lasting under heavy use.

Frequently Asked Questions

What's the difference between abrasive blasting and sandblasting?

Abrasive blasting is a broader term covering various abrasive media, while sandblasting specifically uses sand or a similar fine abrasive. Abrasive blasting is often used for larger or heavier-duty jobs where a coarser or more aggressive media is needed.

What types of structures typically need abrasive blasting?

Larger structural steel, heavy machinery and equipment with significant rust or coating build-up are common candidates for abrasive blasting. It's generally used where the surface area or condition makes lighter preparation methods impractical.

Does abrasive blasting damage the underlying metal?

When the abrasive and pressure are matched correctly to the material, blasting shouldn't damage sound metal underneath. Problems generally only occur when the wrong media or technique is used for the surface.
