Strip It Back to Bare Metal

Old paint, rust and surface contaminants make it impossible to get a protective coating to hold properly, no matter how good the finish is. At JH Protective Coatings, we provide sandblasting in Newcastle to strip surfaces back to bare metal before any coating goes on.

Using the right grade of abrasive for the material and job at hand, we clean machinery, structural steel and equipment ready for priming and finishing, without damaging the base metal underneath in the process. If your project also needs heavier surface preparation, our abrasive blasting service can handle larger or tougher jobs alongside sandblasting. Call (02) 4953 2274 to talk through what your project needs.

How Sandblasting Works

Sandblasting is usually the first step in preparing a surface for long-term protection. Here's what's involved.

  1. We start by assessing the extent of rust, old coatings and contamination across the surface. This tells us which abrasive and pressure setting will get the best result without damaging the metal.
  2. Blasting is carried out methodically across the whole surface, rather than in patches. This gives an even finish and avoids pitting the base metal.
  3. We manage dust and debris carefully throughout the job. This keeps the work area safe and the surrounding site clean.
  4. Once blasting is finished, the surface is left clean and ready for priming or coating. This is what gives a protective finish the best chance of lasting.

Frequently Asked Questions

How is sandblasting different from other surface preparation methods?

Sandblasting uses high-pressure abrasive media to strip a surface back to bare metal, rather than just cleaning or sanding the top layer. It removes rust, old coatings and contaminants more thoroughly than manual methods, giving a better base for a new protective finish.

Is sandblasting suitable for all types of metal?

Most metals can be sandblasted, though the abrasive type and pressure need to be matched to the material to avoid damage. Softer metals generally need a gentler approach than heavy structural steel.

What happens to a surface immediately after sandblasting?

A freshly blasted surface is bare and can start to oxidise quickly if left exposed, especially in humid conditions. That's why priming or coating is usually carried out as soon as possible after blasting.
