Made by Mother Nature, but is still a NUT!

Walnut Shell Blast media is an all-natural, biodegradable, non-toxic and landscape-safe alternative to traditional blast medias.  However if you or any of your co-workers have a nut allergy, we would recommend using an alternate media.

Multi-purpose, proven soft abrasive

Walnut Shell Blast Media has been used for cleaning and blasting operations for a very long time.  This multi-purpose media comes in different sizes depending on your needs.  We consider shells a “crossover” media, which means they are gentle enough to work safely on soft metals and wood construction materials, but can also strip paint and remove tough coatings when applied at higher pressures.  Walnut Shells are very durable which allows for reuse of the shells several times before they break down.
