Im looking to get a few things soda blasted, and was wondering if anyone here has been successful in DIY application of Soda Blasting? Ive seen the links with making your own etc, but didnt want to go and buy a load of bicarb if its not effective.

If you have been successful, i would be interested in how you put the kit together, how much effort it took to clean and how quickly you used the soda!

A bit here:

Thanks, but as above, ive seen these links before here, im looking for someone that has actually undertaken it and been successful before making a mess of my street!

I've done it on the lawn and then washed the residue into the earth.

The bicarb used is very course grained, nearly like rice. Not the stuff you buy for cooking. The stuff my local blaster here uses is very course.

Cheers,

We use a company at work to clean some flues and burners with it and one time they came in I got them to blast a zetec cam cover, it was very effective and left a good surface to paint on to but would be a bit coarse for an untreated finish as it tended to attract oily finger prints very easily.
The good thing about it is the residue can just be washed down the drain with no worries.

Thanks guys. Were the DIY solutions any good? Good points? Bad points? How much effort for the benefit? I was hoping for a bit more than "I've done it"!

What else is there to say?

It's a harmess process. I used it on alloy after I had given it a good degrease and I did it down the bottom of the garden, on a calm day, but I have no neighbours to complain.

Purchased a Millar Soda Blasting Pot from a fellow LCB'er.

These are the initial results after an hour of blasting. The pot arrived in the post with a broken metering valve so ive made a temporary repair until i can get hold of a replacement. This means that the flow of soda is a little temperamental.







Not a bad effort, but needs a bit more. Ive hijacked one of those pop up tents to do the blasting in, which keeps the dust down but is not a pleasant place to be even with overalls, a mask and goggles.

I have a before picture somewhere, but cant find it at the moment.

I think you need a little more air and a little less soda in the mix, it is all about velocity not quantity

I know, but it's difficult to achieve with no metering valve. . Found out hey are £70 today!

I dug out a bag of iron oxide and used that instead.

Thanks Dave. Really good of you to help sort this out.

These are the results with the iron oxide, though the mess is far greater as it all needs washing off etc.
