I have been blasting for 25 years and I have never used an abrasive so versatile as GMA SpeedBlast. If you aren’t using it, you should be.
We were recently introduced to SpeedBlast and tried it in our portable pot to see how it would perform. After blasting just one piece of equipment (a Caterpillar 950 Loader), we were convinced that GMA SpeedBlast could live up to the claims.
This stuff is FAST. It is aggressive on everything we have thrown it at. Paint, rust and mill-scale are no match for GMA SpeedBlast. We have since dumped the steel grit from our fixed blasting equipment and replaced it with GMA SpeedBlast.
In a little speed test I set up, I was able to clean new, one-quarter inch plate to SP5 white metal at a rate of one square foot every six seconds. Do the math, that’s 600 ft2 an hour with a #5 nozzle and 395cfm of air.
