Media – Garnet
Garnet, due to its unique shape, serves as a dual purpose media. Mined in Australia, it gets processed into several different mesh sizes. We stock 30/60, 80, 120, 150 and 200 mesh. The coarser (lower number) mesh sizes work good for traditional surface prep and rust removal projects. Garnet is classified as a hard abrasive, and some people refer to it as the “invisible media”, as a very little amount goes a very long way. The 80 mesh is a very popular formula due to its consistency, which allows you to truly dial in your media flow to just that one grain size so that no garnet goes to waste (in other words, you do not need to adjust your machine to accommodate the largest particle size in a range– when you do have to do this, it’s inevitable that some material will get wasted). Garnet is also highly reclaimable – it can be reused many times before losing its effectiveness.
Using Garnet for Preservation and Restoration projects…
When used at a low pressure in ESCA equipment, garnet can be used successfully for many types of preservation work. It was used at the Eiffel Tower in Paris to remove a layer of wax from the granite base. When using garnet at a low pressure, almost no dust gets generated because of its density. At the Eiffel tower, they “dry-blasted” while using only simple containment measures, and did not have to close down any of the sidewalks or other pedestrian routes.
Garnet was used extensively by the National Park Service at Gettysburg prior to its 150th Commemoration Event for cleaning and restoring many of its monuments and statues.
Garnet can also be used on very delicate substrates, and is widely used in Europe for wood restoration. At a low pressure, garnet bounces off the surface vs. cutting into it. This bouncing action removes dirt, crusts, and other contaminants, but will not harm the wood itself.
Garnet comes in four different mesh sizes to suit your blasting and cleaning needs.
