If you have a fixed structure like a swimming pool, a large industrial tank, or a heavy trailer that isn’t currently road-legal, you can’t exactly drop it off at a workshop. This is why, for many Waikato business owners and homeowners, the biggest hurdle to getting a restoration or maintenance project started comes down to one thing: logistics.
This is why we offer mobile blasting services in NZ. They’re a practical solution that takes away the worry around transport for our clients, allowing us to bring industrial-grade equipment directly to where you are. Compressors, blast pots, media; all of it.
Never experienced mobile blasting services in NZ? You might be wondering about how messy things get, or how much room we need to work.
To answer all your questions, here is a step-by-step look at what actually happens when we arrive in our mobile blasting and coating rig.
1. We assess the site and set up safety measures.
When we first pull up to a site, the very first thing we do is a proper walkthrough with you. This is the most important part of the day because it allows us to establish a safe working zone. We need to find a solid, level spot to park the truck and the compressor, usually within about thirty metres of the object we are working on.
We also take this time to verify the material we are stripping. A thick steel chassis requires a very different approach than a heritage brick wall or a fibreglass boat hull.
Once we’ve identified the substrate and the surrounding environment, we coordinate with you to ensure bystanders, vehicles, and pets are well clear of the area, as the process involves high-pressure air and significant noise.
2. Handling containment and protection.
When we talk about mobile blasting services in NZ, this is the part of the process that tends to surprise people most, because of how much time we spend on it. Since we aren’t in a booth, we have to create a “temporary booth” around your project, and that can take a little while.
We use heavy-duty masking tape and thick plastic or rubber sheeting to cover anything that shouldn’t be touched by the abrasive media. This includes things like glass windows, chrome trim, rubber seals, and any exposed electrical components. For larger industrial applications, we have a dust extraction system that utilises a powerful 3-phase vacuum to capture dust and other particles emitted during the blasting process.
We also lay down heavy tarps or drop sheets underneath and around the project to catch the spent media as it falls. This prevents garnet or glass from mixing with your soil or driveway, making cleanup much faster.
3. Picking the right blasting method.
Often, we would already have the blasting method selected during the quotation process. But in some cases, we’ll need to decide on a different blasting method on-site, or assess in the moment to determine which media is best.
In many mobile residential jobs or busy commercial areas, we opt for vapour blasting, also known as dustless blasting. If we are out on a farm or in a wide-open industrial yard working on heavy rust, we might go with traditional dry blasting because it’s a bit faster for certain types of heavy-duty steel.
Regardless of which call we make, we’ll always talk you through our decision and why it’s the best fit for your specific location.
4. Kicking off the blasting process.
When the actual blasting begins, it is a systematic process. You’ll hear the compressor running loudly, and you’ll see our crew in full-body protective suits and respirators. We work across the surface in sections, stripping away the old paint and rust until we see the “white metal” or the specific etched profile we are looking for.
Of course, this depends on which mobile blasting services in NZ we’ve recommended for your work. If we are working on something delicate, like a car body or thin aluminium, we take frequent breaks to ensure the metal doesn’t get too warm, which is essential for preventing any warping or distortion.
This will also depend on the type of blasting and coating we’re doing (i.e. vapour blasting carries heat away, so it needs fewer breaks).
5. Handling cleanup and media removal.
As the blasting wraps up, we shift our focus to the cleanup, which is just as important as the stripping itself. We start with a thorough “blow-down,” using high-pressure air to get into all the nooks, crannies, and frame rails where the media likes to hide. We want to ensure that as little grit as possible is left on the surface.
Once the project is clean, we move to the ground. We sweep and vacuum the spent media from our tarps, then bag it. In most cases, we take this waste with us for proper disposal, leaving your property in the same condition it was in when we arrived (just with a much cleaner piece of equipment or structure in the middle).
6. Final inspection.
Finally, we go over our work for a quick inspection. In the damp Waikato air, bare steel can start to turn orange with “flash rust” within just a few hours. After we complete a final walkthrough with you to ensure everything meets your expectations, we take steps to maintain that clean finish.
If we’ve used a wet-blasting method like vapour blasting, we will have already applied a professional-grade rust inhibitor. This is a chemical added to the water reservoir that keeps the metal from oxidising for a few days, giving you enough time to get a primer on.
Many of our clients actually ask us to apply a zinc-rich primer ourselves immediately after the blast, which is often the best way to ensure the metal stays in perfect condition until you’re ready for the final topcoat.
What we might need from you:
To ensure the entire visit goes smoothly, we usually ask you to help us provide sufficient access for all equipment and to line up standard power connections for our smaller tools and lighting. Aside from some site downtime in the area we’re working in, this is virtually all we’ll need from you to get the job done.
There you have it! A quick overview of the process for our mobile blasting services in NZ. You don’t need to deal with towing companies or worry about your project sitting out in the elements for weeks. We’ll just show up, get the surface prepped, and get it sorted. We’ve designed this to be as non-intrusive as possible while still delivering the best results.
All that’s left is to try it out for yourself.
