Our latest project Holden VL sandblasting and Spray Painting for Jake

<strong>OUR LATEST PROJECT</strong>
Jake brought his Holden VL into Ublast Pty Ltd and asked “What is the best way to strip my car and get it re sprayed? Rather than stuff around with a bit of rust repair here and paint touch-up there, I’m considering taking it to someone and having it stripped back to bare metal and resprayed in the same 2-pac metallic light blue or crimson red? Obviously the cost would depend on the extent of rust repairs required, but excluding that how much (roughly) would I be looking at to get the full rub back and respray?”
We explained in detail to Jake the most efficient way is to totally strip his car of all the trim, take windscreens out, remove all your interior and exterior parts. Once you have prepared your car, bring it into Ublast and we will start the process of sandblasting it. When the sandblasted car is complete we can clean out all the abrasive, vacuum all the contaminates and start prepping it for spray painting.
You can spend a fortune and end up with a poor job or take it a professional company and get them to do a fantastic job. We want to make sure Jake gets a fantastic job and is happy with the finished product. Preparation of any surface is the key to making sure the paint sticks to the surface properly. With a clean surface the paint will adhere so much better and last a lot longer, there are several ways to remove paint and rust, acid dipping, chemical application and more. The most efficient way is sandblasting. No more preparation is needed after your item has been sandblasted especially for metal items as the surface is back to it’s original state and ready to be etch primed and have base coat and top coat applied.

Bedford Van for sandblasting This is our project at Ublast Pty Ltd or Narre Warren Sandblasting

Bedford Vehicles, usually shortened to just Bedford, was a brand of vehicle produced by Vauxhall Motors, which was ultimately owned by General Motors (GM). Established in 1930 and constructing commercial vehicles, Bedford Vehicles was a leading international lorry brand, with substantial export sales of light, medium, and heavy lorries throughout the world. It was GM Europe‘s most profitable venture for several years. Bedford’s smallest products, car-derived vans, were the Bedford HA van, which substantially outlived the Vauxhall Viva HA on which it was based, and the Bedford Chevanne, a short-lived variant of the Vauxhall Chevette. An estate conversion of the HA van by Martin Walter was marketed as the Bedford Beagle. This was further developed into a camper van, the Roma, again by Martin Walter.

This is our project at Ublast Pty Ltd or Narre Warren Sandblasting

We are helping Craig restore his Bedford Van by sandblasting all the old paint and remove the rust from the surface. You can see if the pictures this Van needs some loving and with hard work and time, she will look fantastic again. Craig has asked if we can sandblast underneath and the exterior of the van to prepare it for spray painting. The roof and side walls are fragile and sand blasting can damage the panels. With our air pressure turned right down and using a very soft abrasive, we can confidently sandblast all the panels and roof without any warping. These Bedford Vans are a classic antique vintage car and removing the paint and rust would take extremely long hours to remove by hand. Sandblasting is the quickest way but you still have to be careful in the application of paint stripping.

Once this Bedford Van has been sandblasted, Craig can take it and apply an etch primer to protect the van from further rusting. With some light sanding and preparation to get the van ready for spray painting, she will be back on the road in no time.

Sandblasting Spray Painting Hallam

Ublast Pty Ltd has a sandblasting and spray painting room for any type of object.
Whether you have a car trailer truck boat outdoor setting bumper bar ute tray wheels gas bottle tool box, we can help you restore your item and have it looking brand new again.
Sand blasting is still one of the most efficient ways to clean the surface to be ready for the spray paint to be applied. Once the surface has been sand blasted, you can apply the paint with confidence knowing your product will be protected for years to come.
<strong>Why is sandblasting used?</strong>
Sandblasting or abrasive grit blasting is a surface treatment process widely used in a variety of different industries with many diverse purposes. Sandblasting or abrasive blasting is the process by which an abrasive media is accelerated through a blasting nozzle by means of compressed air.  Narre Warren Sandblasting is part of Ublast who also are an online shopping website for Air Compressors and Sandblasters, air tools air hose and more. We are a premiere company that focuses on customer satisfaction.

what size air compressor is the best for sandblasting?

what size air compressor is the best for sandblasting?

The best size air compressor for sandblasting depends on the size of your sandblast nozzle. Determining the size of the nozzle most often helps to understand the perfect size air compressor for sandblasting. Maintaining constant pressure with your sandblaster will enable the most efficient cost of blasting your items. The lower the cfm (cubic foot per minute) the longer it takes to remove paint, rust or general cleaning from the surface. With a smaller size air compressor the pressure at the nozzle will constantly drop until the point where the air compressor can only maintain the maximum amount of pressure that the air compressor puts out.

Screw air compressors are most commonly the better types of air compressors to use when sandblasting as they are able to keep a constant cfm air flow. Screw compressors also are designed to work hard and not create any issues running hot or overloading. Piston compressors are designed to start and stop at least 4 times every hour and have a duty cycle. Piston machines are great for small to medium sandblasting operation whereas a screw machine is better for medium to large operation.

Sandblasting pressure blast pots work best with a dry air supply. Having an air dryer whether it is refrigerated or not allows clean fresh air to your blaster and avoids any types of blockages or condensation problems within your sandblast pot. When condensation (water) enters the sandblast pot it will create a blockage and limit the abrasive supply to a point where no abrasive can be produced to the blast hose & nozzle. If this happens you have to stop blasting, take the pot apart and clear the blockage and fix the condensation problem to start blasting again.

Listed below are the specifications on what size nozzle should be used with the size air compressor;

  • Nozzle 1/8″ 100 psi 21 cfm
  • Nozzle 3/16″ 100 psi 45 cfm
  • Nozzle 1/4″ 100 psi 80 cfm’
  • Nozzle 5/16″ 100 psi 142 cfm
  • Nozzle 3/8″ 100 psi 200 cfm

These specifications are based on sandblasting pressure pots usage and may vary depending on the size blast hose and air hose you are using. It is always the best rule to have more air when sandblasting than less to maintain a constant pressure at the nozzle to maximise your efficiency. Ublast Pty Ltd have all the correct specification available and we can help to make sure you have the right size equipment to sandblast your items.

what size air hose do i use with my air compressor

what size air hose do i use with my air compressor

The answer depends on your tolerance for air hose problems, what type of work you plan on doing with your air compressor and the air hose, and as always, your wallet. Is change in your compressor air hose worth it for you? What type of air hose do you use, pvc, rubber?

If your air compressor is a typical single phase then it will have the most efficient use with a 6mm to 10mm air hose. And also typically the length of the air hose should be no more than 30 metres to avoid any pressure drop.

What Size Air Compressor Do I Need?

what size air compressor do i need?

Depending whether you need an air compressor for commercial or residential needs, the air compressor should have a bigger free air delivery than the air tools you are using. An example could be you need to pump up truck tyres, you want to save money and purchase a small 240 volt compressor but in reality you need a 3 phase compressor. You can buy a single phase 240 volt compressor that pumps up to 140 psi instead of 115 psi.

There are many options when purchasing an air compressor, always ask a professional that sells compressors for the right advice on what type, size and brand of compressor you need.
