#80 Aluminum Oxide 12 LBS Sand Blasting Media - Long Lasting

In this review of the #80 Aluminum Oxide 12 LBS blasting media, the bottom line is simple: it is for users who need a durable, aggressive abrasive that cleans and etches a wide range of surfaces with fewer reloads. The reviewer found the material especially useful for glass etching and paint removal because aluminum oxide hardness outperforms common glass media and resists breakdown, delivering longer cycle life and consistent cutting action across wet or dry blasting jobs.

Key Features

• Hardness and performance: The abrasive is the second hardest mineral after diamond, so it cuts and etches effectively on metal, glass, stone and wood.
• Long lasting grit: Sharp, angular particles maintain cutting edges longer than typical silica media, reducing media consumption and downtime.
• Non-reactive: The product will not interfere with coatings or surface prep chemistry thanks to its non-reactant nature.
• Low silica content: With no detectable crystalline silica, it offers a safer profile compared to traditional silica sand and extends usable life about ten times longer than silica.
• High density: A specific gravity of 3.9 and a bulk density near 115-125 lbs/ft3 deliver strong kinetic energy for aggressive material removal.

Who It's For

The #80 Aluminum Oxide in 12 lb bags is aimed at hobbyists and professionals using handheld blasters, blasting cabinets or blasting guns who need a high-abrasive-force media for paint removal, deburring, and glass etching. It works well where long media life and consistent cut rate matter, such as repeated prep of metal parts or restoration work.

Those who should look elsewhere include users requiring extremely fine cosmetic finishes where gentler media is needed or projects limited by strict regulatory handling of abrasive dust; select a softer or finer grit for delicate surfaces or enclosed environments that demand specialized dust control.

Pros & Cons

Pros

• Very durable and long lasting, so bags are used for more cycles than silica alternatives.
• Effective at etching glass and removing paint due to the high hardness and sharp, angular grit.
• Non-reactive and unlikely to interfere with later coatings or surface prep steps.

Cons

• Its aggressive nature may be too harsh for delicate or thin materials where a softer media would be better.
• As a dense, abrasive product it requires appropriate blast equipment and dust control to operate safely.

Specifications

Our Verdict

The #80 Aluminum Oxide 12 LBS bag is a strong value for users who need an aggressive, long-lasting abrasive for blasting cabinets, guns or handheld units; its durability and ability to etch glass make it particularly useful for mixed shop work. Buy this if you want fewer media changes, predictable cutting performance and a media that stands up to repeated use.

Frequently Asked Questions

Can this media be used on glass?
Yes. Its hardness is greater than glass so it is suitable for etching and surface preparation of glass.

Is there crystalline silica in this product?
No. The product is described as having no detectable crystalline silica and lasts far longer than silica sand.

What equipment works with this media?
It is compatible with blasting cabinets, sandblasters and blasting guns; users should ensure their equipment and dust control are rated for dense, aggressive abrasives.
