Choosing the best garnet grit to blast boats

When wanting to provide a nice finish or remove corrosion from the hull of your boat, abrasive blasting is a great method to use, but you should consider the grit size of the abrasive media. Garnet sandblasting makes use of an air compressor to propel blast abrasive grains through a nozzle at high velocity onto your chosen project surface. It has various applications, including boats and marines. 

Garnet is a common blast media that is used for treating metal surfaces and the hull of boats. Just because it’s common, though, doesn’t mean it’s the best abrasive blast media on the market. Superoxalloy – discussed at the end of this article – is the best all-purpose media to use for your blasting jobs. Before purchasing a blast media, it’s important to consider the grit size. The higher the grit number, the finer the abrasive is, which creates a smooth surface finish. Lower grit numbers mean the abrasives are more coarse, which cause thick materials to scrape off much quicker.

As you can see, there’s quite a bit to take into consideration, but fortunately there’s a far easier method for getting the job done without relying on garnet. 

The Best Blast Media for Boats

10X Engineered Materials’s line of superoxalloy abrasives are more efficient than the alternatives and can be used on a variety of boat hulls made from aluminum, wood, and steel. 10X products include KinetiX (high-production grades) and EpiX (precision grades), both of which perform in finer grit sizes, as well as or better than expensive, clean, ultra-high-performance media.

These abrasives are made up of polymorphous particles, meaning they can perform multiple functions at one time, removing the layers quicker and more efficiently in just one step. Additionally, these abrasives are strong but gentle and will leave the underlying surface unharmed. 

Currently, KinetiX and EpiX are available from abrasive distributors around the US. If you don’t see a distributor near you, contact 10X and we will work with you to get you what you need. EpiX abrasive, which is best for precision applications such as powder coating and medical applications, is also available to purchase directly from the 10X Engineered Materials website.
