Frequently Asked Questions

Q. Is there any residue left on the cleaned surface?

No, once you have pressure washed with Rust Inhibitor (Holdtight102 or Holdblast) mixed in your water, nothing is left, not even the rust inhibitor. Once the surface is dry it is ready to paint.

Q. Since water is used, won’t it rust metal?

We use a rust inhibitor called HoldTight® 102 or Holdblast to prevent flash rusting for up to 72 hours. This extremely effective rust inhibitor is added to the blast water to prevent flash rust during blasting, and then used to rinse after blasting is complete. Watch the Holdtight Do’s and Don’ts video to learn more. http://www.youtube.com/watch?v=L61ICEyIKa4

Q. How much water will the unit use per hour?

All machines will use around 80 litres at maximum pressure/media setting.

Q. Are there any water quality specifications required for the Dustless Blasting Machines?

Yes, clean water. If the water is hard or bore water more Rust inhibitor (Holdtight 102 or Holdblast) will need to be added. The job you are blasting will be as good as the water used.

Q. Does the Dustless Blasting process always leave the substrate unaffected?

This depends on the hardness of the substrate and the blast media used as far as profiling is concerned. It will however NOT discolour or alter the PH of any surface. If you don’t want to profile steel use plastic blast media. Our machines are multimedia capable so you can use whatever blast media required to give you the desired result.

Q. What happens to the abrasive after blasting?

The abrasive will settle on the ground beneath or very near to whatever you’re blasting. If you’re in a place where you need to dispose of this media, the easiest way is to spread out some plastic before you begin blasting, and roll it up after blasting.

Q. What's the risk/impact of glass residue being left on a site?

The glass is not a problem as it is neutral and has no adverse effect on soil or the environment. What needs to be considered is the impact/risk of what you are removing, i.e. lead paint. This can be easily cleaned up by us folding drop sheets containing the media and waste and then disposal in approved manner, either by customer or operator as contracted .

Q. Given the process is Dustless, does that mean I would not need a booth with extraction/ventilation in my workshop?

Extraction would not be required. A shade cloth surround is ideal to capture water vapour. We always blast in a well-ventilated environment due to the fumes produced from the diesel engine of the compressor, but can also Blast in confined spaces with extra equipment.

Q. Does wet Garnet Blasting do the same thing as wet Glass Blasting?

Basically yes, however the media is heavier and holds moisture much longer than crushed glass, thus making clean up cumbersome and labour intensive. In comparison the crushed glass dries in around 5 minutes and remains light and loose making it very easy to clean up.

Q. Will the Dustless Blaster damage chrome and glass?

Glass and chrome can be damaged by any kind of abrasive blasting. We / or client will always mask off the chrome and glass prior to blasting. The Dustless Blaster is quite accurate and can be aimed right up to the edge of glass with low risk of rebound damage.

Q. How does the Dustless Blasting process perform on wood?

Dustless Blasting using crushed glass is very effective on hardwoods only. Even soda will damage softwoods. Once again it depends on how hard the coating you are removing is as to whether the timber underneath will sustain any damage.

Q. Does the Dustless Blasting equipment comply with Australian Standards?

Yes, pressure vessels are AS/1210 and design verified under that standard.

Q. Do you have any Safe Operating Procedures (SOP) for the equipment?

Yes, we have a (SOP) Safe Operating Procedure for the Dustless Blasting equipment. Copies are available on request free of charge.

 

Q: Are your processes effective at removing paint adhesion from base metal?

No problem. Our glass blast system is approved by paint companies. The recycled glass media we use is PH neutral and no residual glass imbeds to the surface because the media is softer than metal.

Our blaster does not scour the surface roughly. Leaving you with nice smooth panels to paint.

Q: Is dustless blasting safe to environment?

Absolutely safe, the glass blasting media is inert and PH neutral. The paint or coating being removed may have some toxic qualities. We install plastic sheeting and barriers as needed, then bag up waste on completion.

Q: What concerns should I have about health and safety?

Very little risk. We use a paper mask and eye protection because we are close to the blasting operation.

No dust. This system uses water that vaporises under pressure at the nozzle. Dust particles are captured with moisture and fall directly at our feet.

What about noise? We use a diesel powered air compressor, which has been silenced by the manufacturer, however it still can be a nuisance. The public love us because we are quick!

In a public walk by situation we erect a safety panel barrier around the work site just to avoid the possibility of grit in a bystander’s eye, but mainly so we can complete the job quickly without interruptions from questions and congratulations. 

We carry trip hazard covers for our compressor hoses in high traffic or risk situations.

Q: What about warping of metal?

No. Blasting with our process doesn’t cause heat! So no warping from this issue. We need to be careful particularly on the underside of bonnets as the blaster is powerful, but the system is safe for your precious car and light years ahead of sand blasting.

Q: Will it leave residue glass inside my car panels?

A very small amount may occur. You can vacuum out quite successfully unlike sand as the glass fibre is light. Glass is inert and wont hold moisture – therefore no rust issues.

Q: Can you work on scaffold or at heights?

Yes, we can. Though the scaffold must be safely and correctly installed.  We also have safety harnesses where we are at heights or under bridges, etc.

Please advise if this is a factor when you first speak to us.

Q: What is involved at clean up?

Normally we have little waste to clean up and don’t include this in our standard rates or quotes.

We are happy to clean up – just ask for this, we will quote you.

Q: Do you do big jobs or small jobs?

  • Yes we can arrange big jobs completed quickly.
  • Yes we can do small jobs. Best to bring the item to us if you can or we schedule your job with others in the area if we have to travel. Otherwise call out travel fees may apply which can become expensive.
  • Call us for advice or a quote.

Q: Can you always come mobile to my job site?

Yes to most sites, including on an Island by arrangement. We have a trolley type blaster if you have a difficult location to get to.

If you are a long way from our base, call us and we will consider what we can do for you.

Q: Which base surfaces can be blasted?

  • No problems for steel or hardwood.  
  • Stainless steel tends to dull and remove the polished appearance. We avoid unless the client instructs us.
  • Softwood. Yes. We can clean mould and softer coatings using a granulated softer plastic or bead media. If we are to remove a hard coatings like paint from a soft material we have a problem as the abrasion required to strip the paint is often too harsh on the base surface and will scuff it – we suggest chemical stripping in this instance.

Q: Surfaces that can’t be blasted –

  • Glass – this will cause a frost effect, so we cover with 2 layers of plastic tape for prevention.
  • Chrome or stainless steel – will dull the polish

Q: Can you remove paint from asbestos?

No, we cannot come into contact with asbestos. Airborne micro particles are very hazardous to health. Asbestos must be removed by a licenced contractor.

Q: Will you damage rubber components?

No, taping with 2 layers of duct tape will safeguard this.

We can even remove graffiti from playground soft fall rubber matting without damage.

Q: Are bearings and seals at risk with glass blasting?

Generally not, we are careful not to direct the blaster to bearings and the glass media is softer than metal.

Q: Do you apply an antirust primer?

Yes we can wash down with “hold fast” antirust primer. This will protect bare metal for up to 72hrs, giving you time to prime.

Q: Can you paint as well for me?

Yes, we will paint structural items to General Standard by arrangement. We are not skilled automotive painters; if you require an expert finish we recommend that you contact an expert tradesmen.

Q: Can you remove lead paint?

Yes, we can safely blast clean lead paint to prepare for new paint coatings without damage to hardwood siding, etc.

Be sure to request a quote, as we need to allow for ground sheets, clean up and disposal which is extra to our normal price.

Q: What can you clean?

  • Rust, paint, pool coatings
  • Mould, soot, oil stains and grime
  • Brick, concrete, steel, aluminium
  • Calcium, cement slag
