Garnet Abrasive Buying Guide

Not all blasting projects require the same abrasive. This guide helps you quickly determine which Australian garnet blend best suits your surface preparation goals — from aggressive coating removal to delicate substrate cleaning.

Step 1: Understand Your Project Goals

Before choosing a blasting abrasive, ask yourself:

  • What type of surface are you blasting? (Steel, aluminium, stainless, concrete, etc.)
  • What coating or rust levels need to be removed?
  • Is this for new steel, heavy maintenance, or precision restoration?
  • What surface profile is required for coating adhesion?

Step 2: Choose the Right Garnet Blend

GMA Garnet for Tough Jobs

GMA Garnet’s range of blast media mix coarse and fine grain garnets, achieving the optimal balance between cutting and cleaning power.

REDUCE OVERALL PROJECT COSTS

GMA Garnet results in higher productivity and lower abrasive consumption, despite the higher initial product cost compared to slags. With GMA Garnet, you can save 15% to 30% on a typical project due to lower cleanup and equipment costs, and reduced labor and blasting time. This makes GMA Garnet far more effective and efficient than other abrasives in the market.

Although the typical slag abrasives and other garnets cost lower per ton, these are often inferior in quality and performance, resulting in lower productivity at a higher consumption rate. In fact, more abrasive is needed to complete a project. This dramatically increases your cleanup, disposal, labor and equipment costs and ultimately, increases your total project costs.

LESS WASTE, MORE PERFORMANCE

GMA Garnet has a unique blend of particle sizes which guarantees you more grains per pound. The end result is you use significantly less abrasive to do the same job when compared with imported garnet.

Abrasive blasting relies on impact to remove unwanted material. More impacts = higher production.

GRAIN SIZE MATTERS

While coarse abrasives excel at removing thick coatings and creating deep profiles, they leave behind embedded particles and struggle with cleaning small, recessed areas. This translates to wasted abrasive, slow cleaning times, and a higher risk of future corrosion due to inadequate cleaning. Conversely, fine grains excel at cleaning and removing thin coatings, but lack the punch for thicker layers or deep profile creation.

Traditional abrasives force you to choose between removing the coating or properly cleaning the surface – you can’t achieve both effectively in one go.

GMA Garnet bridges this gap by offering exceptional cleaning power alongside fast and efficient coating removal at a lower consumption rate. This translates to a cleaner surface ready for inspection and coating application, all achieved with minimal abrasive waste.
