Product Overview
Garnet 20-40 or Garnet 20/40 is a coarse-grade abrasive that cuts through heavy rust, thick coatings, and tough mill scale on steel surfaces fast. The particle size sits between 0.42 mm and 0.84 mm. It produces a surface profile between 85 and 105 microns. Paint and coatings stay in place for a long time when the surface has that level of texture. Site managers on marine, oil and gas, and construction projects pick Garnet 20 40 Mesh Dubai because it gives the surface exactly what it needs before the coating goes on.
Features & Benefits
- Natural hardness: It scores 7.5 to 8 on the Mohs scale, so it cuts through hard surfaces with ease.
- Coarse particle size: Particles sit between 0.42 and 0.84 mm, so they strip thick coatings off fast.
- Low dust output: It produces very little dust during blasting, keeping the work area much cleaner.
- No toxic materials: It contains less than 0.1% free silica, making it safe for operators to use.
- Reusable: You can reuse it multiple times without losing its cutting performance on site.
- Strong surface profile: It creates an 85 to 105 micron profile that helps coatings stick firmly to steel.
- No nozzle clogging: The uniform particle size moves through blasting equipment smoothly without blocking.
- Sub-angular grain shape: The grain shape gives fast, aggressive cutting with a clean surface finish.
Applications
- Cleaning rust and heavy coatings from ship hulls.
- Surface preparation of steel structures before painting.
- Removing thick scale from oil and gas pipelines.
- Cleaning industrial storage tanks before coating.
- Preparing steel beams on construction sites.
- Waterjet cutting of metal, stone, and glass.

Frequently Asked Questions
- What is the particle size of Garnet 20-40?
The particles measure between 0.42 mm and 0.84 mm. This is a coarse grade built for heavy industrial surface preparation work.
- What surface profile does this grade produce on steel?
It produces a surface profile between 85 and 105 microns. This level suits high-build coating applications on steel structures.
- What is the consumption rate per square metre?
The consumption rate starts from 15 kg per square metre under standard blasting conditions on site.
- What is the blasting rate for this grade?
You can blast up to 20 square metres per hour depending on the equipment setup and surface condition.
- Is this grade safe for blasting operators to use?
Yes. It holds less than 0.1% free silica and throws very little dust into the air. It meets standard health and safety rules on any job site.
- Can Garnet 20-40 be reused on the job?
Yes. You can recycle it multiple times in a proper blasting system without a major drop in cutting performance.
- Which industries use this grade of garnet abrasive?
Marine, oil and gas, construction, and heavy manufacturing sites all use it to clean and prepare surfaces before coating work.
- Can it also be used for waterjet cutting?
Yes. The 20-40 mesh size works well in waterjet cutting machines that cut through metal, stone, and glass.
- What blasting equipment works with Garnet 20-40?
It works with standard pressure blasting pots and suction blasting systems used in industrial surface preparation.
- How should this abrasive be stored on site?
Find a dry spot on site and keep it there. Water does not affect garnet, so it stays in perfect condition until your next blasting session.
