Ive been checking the net for different blast medias out there and came across a product called Sponge Jet, im sure a few of the veterans out there know what im talking about. Not sure of the cost but I am very impressed with the low or no dust results of the media and the ability to clean fast and to spec. Thoughts anyone, im going to get more info from the company tomorrow.
Sponge jet media and blast equipment???

Sponge jet
It has its applications,
But if I had to spend the money I'd buy a good blast rig, I had a fellow contractor in the fire restoration business who bought the rig and a classifier,And was offering to sale it to me.
It was close to 30k no compressor included, I can do everything it can do with my blaster and I have more production.I can also get a lot more bang for my buck.
The advantage is low dust and the media is not real heavy of sponge rubber with abrasive glued to it. I tried it out on brick job removing soot, it did ok.the low dust and clean up were great, but the media was more expensive and did not clean as fast as soda.But you can sweepit up and re-use it.
Not trying to dog the equipment, I just like mine better having tried one

My old employer tried to use the Sponge Blast. (We used to call it Sponge Bobin’)
The problems outweighed the effectiveness of the product.
We would Blast for 1 hour and clean for 5. Recycling it as we went.
They had a machine to dump the media into, shaking it out into 3 sizes. Lots of labor involved.
Although we had lots of problems over several months, the Blasting results on the product was good.
As with any thing it had its ups and downs.
The company abandoned it after a few months.

Sponge Blasting is great!
Our company has been using Sponge Media for 3 years now. We wouldn't use anything else. We take 15 mils off of steel and achieve a 2.5 mil profile at the same time. We get 10-15 reclaims out of each lb. They put the following in the Sponge: Steel grit,aluminum oxide, Starblast, plastic, glass, calcium carbonate, etc. With the aluminum oxide, they go from 16 grit to 500 grit. It can achieve 0 - 4.5 mils profile with one system. So the fact that this system has no limitations on what it can be used on, is a great opportunity for blasters. They also have vacuum systems that can be put on the recycler so that the blaster does not have to stop blasting to recycle, it does all the work for you. A school is 200 feet away and the city would not let us use anything else besides Sponge Media because of the low dust.
Hope this helps.....

Although I have tryed it in the "Navy" Setting
I have not tryed it out side.. so for me to say it does not work is a wrong thing for me to say, I did not work right for the Navy contrctors I worked for.
They did not have the proper set up for what they were trying to achieve. with the vac and other type of grit imbeded I think it would have been valubale to them.
Can you show us some pics of projects done?
Cars, Equipment, schools, BOATS, ETC...??? :thumbup:

it does have its place but everyones negative claims on here have good validity.
negative
It is expensive.
Initial investment is high
media is high
production is low
cost for gathering grit to reuse in a non permanent shop application can far out weigh the savings of using reusable media.
positive
its a neat novelty toy for professional applicators
it is better used in a shop blast room where everything is confined.
it does have low rebound.
there are a variety of abrasives to use for different applications.
it does have its place but is not a wonder piece of equipment like it is promoted. enviromediaman sells the equipment.

Most coatings actually only require a 2.5-3.5 mil blast profile. That would be coatings that are applied at 6-12 mils. Maybe even a little thicker. 4-6 mil deep profiles are really only required for thick film coatings such as polyurea's and high build Elastamerics in the 30 to 125 mil range.

For me, it's slowly as hell. How long will take to blast the whole pot ? Month ?
Guy above telling us how good is that method, propably is seller of these machines...

Your not getting it's use. It is slow but not that slow. Just imagine having to enclose that area and create a negative pressure chamber to use conventional blast equipment in. By the time your all set up you could have done the job with the sponge jet. That's what's it's purpose is for. They can even remove Polyurea coatings and elastomeric coatings with it. It's just another tool in our tool box guys. They have there place in the industry. They have been around for a long time now. I was first introduced to it back in 1998.
