    Portable Sand Blaster

    Hi All,

    I am thinking about buying a portable sand blaster - to do large panels that don't fit into my small sand blaster cabinet.

    Naturally I already have the media, and know that I have to be careful which media I use on what type of metal.

    I was thinking about something like this:

    Has anybody had any experience with one of these OR could you recommend a unit?

    My plan would be to set-up a cheap Bunnings Gazebo, buy a proper face mask / breathing unit - and blast away.

    Any recommendations?

    Cheers,
    GG.

    The bigger issue is a large enough compressed air supply to run it for a long enough period of time, I've considered similar abrasive blasters but I need a much bigger compressor to run one so haven't gone down this route yet.

    I get the impression the blaster works OK as long as you have reasonably dry air.

    I know someone that can supply a large enough compressor when needed. Portable Sand Blaster

    It would be a diesel powered trailer unit.

    "...a diesel powered trailer unit" - I want to blast of paint, not blast the panel into the next suburb!!!

    I'm just thinking out loud here - somebody has attacked various panels on the 107" with I think a wire brush.

    My initial thought process was - sand back all of the paint, wet sand the scratches out (hopefully) and leave it as is.

    I can see that a portable unit has it's limitations - if you look at the advertisement, I rekon that you would only be able to blast for a minute before you have to fill the funnel up again.. It's just an idea..

    Although the Wandong Sand Blaster business is up for sale...

    Some air tools like blasters, die grinders, belt sanders require high flow so if you don't like stopping and waiting for the reservoir to refill then you need a high flow compressor. Few 240 volt compressors are high flow. Flow gives speed, pressure gives force. Same as hydraulics.

    Have you considered a water based abrasive blaster? Eg karcher / gernie attachment.

    I have just used a water blaster on my door frame. It instantly rusted! Just something to be aware of.

    The blaster shown will be a waste of time.
    It will make a big mess as it doesnt recycle the media like a cabinet one, use lots of media and will not be very effective.
    You need serious air supply and a effective way to contain the waste media.
    The gun and nozzles shown are not long lasting or effective.
    A pressure water cleaner with abrasive pick up would be better with no dust, but you still have to clean up the wet mess afterwards.
    Pay to get your stuff blasted, it is usually good value.
    Needle guns work well bang for dollar wise with some jobs.
    Professional quality sand blasters use boron nozzles and serious diesel driven air supply in a contained dry area ...........smaller inbetween gear has trouble doing things with enough speed or power.

    The best way I have seen for doing alloy Landrover panels is paint stripper.
    Cost effective and just use a water pressure cleaner to remove.
    The scratches sand and fill with primer and paint as normal.
