aldi sandblast gun

Has anyone used one of these? I have flaking alloys that need to be sprayed and sand blasting seems the best option for the shape of them, what do you think about the Aldi gun?

What do you plan to so after sandblasting, painting them?

The reason I ask is that we used to have a sand blasting gun in work for sand blasting onto metal. We constructed a special container to stop the sand going everywhere and we had a compressor too. It might just be better for you to get a company to remove flakes.

Tallaght Powder Coaters will do the whole job for not alot of dosh (media blasting and then repaint/powder coat).

Fast turn around time too.:)

Theres also the chap who does the sand/media blasting on Howth Pier.He does everything from fishing trawlers to alloy car/bike wheels.

Hes very good too.:)

I have an Aldi sandblast gun that I bought a long time ago. Sandblasts work best with sharp abrasive (like crushed foundry slag) that can be purchased from such firms as Clarke Distributors, but I found that dried building sand works quite well for small jobs and is cheap. However, sharp sand won't work as the particle size is too great for the Aldi device. Anyway, the tool has done pretty much anything I wanted in DIY.

Art6, could this be used to sand intricate shapes before painting, I.e painting the likes of a brass bed or ornate cast iron gates etc ?

Ate these in Aldi at the moment? Any idea of price?

Thanks,

I've used it for things like that, but I'm sure it would work better with proper blasting media. Using building sand just takes a bit longer.

I bought that kit from Aldi a couple of years ago and found it a complete waste of time- the trigger mechanism would jam when a stray bit of abrasive got stuck in the mechanism. Nice idea but I think you need to spend money on a quality gun for this purpose, just my experience.

How did you get grit stuck in the trigger mechanism? The trigger is in the air line, not in the grit delivery. Certainly DIY versions nozzles can block if the grit is too coarse, which is why I use fine builders sand sieved through a fine kitchen strainer to get out any bits of stone etc.

Thanks for the replies guys! I would get them powdercoated but I love to be self sufficient, I change the colour of these wheels quite often and usually hand sand. The last job I did though I got a bad chemical reaction (i don't have a booth, all outside) but the idea of a sandblaster sounds good.

Very easy happen, some of the abrasive blew back when I was trying to use the gun on the inside of curved steel panel. Freed up the trigger only for it to happen again a short time later- using the supplied carborundum grit. Waste of time for me unfortunately.

I have one I'm not using if you want, pm me for details.

I was using it for heavily corroded metal and didn't find it very efficient; it would clean it off but needed several passes, not sure if my compressor is too small for it - I didn't use it to remove paint so can't comment on that.

Something similar to this might be a bit better :

I also bought the kit and totally agree with you. it will not work under 80psi

Don't get in the habit of using silica sand - silicosis is no fun at all

Painting aluminium you need to use an etching primer first and this must be done as soon as you get it blasted "I find soda blasting works best" as the aluminium will start to oxidise within a few minutes, if you use sandpaper it tends to just rub dirt and grime into the aluminium leaving dark marks that the paint will not stick to. My two cent go with the pro's and save yourself a lot of time, effort and cash

Give it nice acid wash and chromate it - skull n crossbones = mark of quality
