Product Information

Full details

The Mirka Iridium Sanding Triangle is an ideal abrasive solution for professional contractors and woodworkers who require high material removal rates and a consistent finish on complex surfaces. Its specialized anti-clogging coating and high-performance grain adhesion ensure a longer operational life, though users should ensure they are using a compatible 36-hole dust extraction sander to maximize the effectiveness of its unique airflow design.

FAQs

What is the best way to choose the right grit?

Start with a lower grit (40-80) for heavy material removal and move to higher grits (180-320) for fine sanding and finishing.

Can I use this for wet sanding?

Mirka Iridium is primarily designed for dry sanding applications. Consult the technical data if specific wet-sanding needs are required.

Is the 36-hole pattern compatible with all sanders?

It is optimized for 36-hole pads; however, it can be used on other pads provided the vacuum holes align or the pad size matches.

How long should a single sheet last?

Due to the anti-clogging coating, these sheets typically last longer than standard paper, but lifespan depends on the hardness of the material being sanded.

Does this product work on metal?

Yes, it is effective on steel and other mineral materials as well as traditional wood and paint surfaces.

Troubleshooting

Abrasive is clogging quickly

Check that the vacuum or dust extraction system is pulling air through the 36 holes; empty your dust container or clear the hose of any blockages.

The triangle is not sticking to the sander

Check the hook-and-loop backing on your sander for dust buildup or worn-out hooks; clean the pad with a soft brush or replace the backing pad.

Pros and Cons

Pros

  • Excellent grain adhesion ensures durability
  • Highly effective dust extraction system
  • Versatile across many surface types
  • Ideal shape for corners and detailing

Cons

  • Requires specific 36-hole sander backing pad for best results
  • Performance heavily dependent on dust extraction setup
  • Not intended for large, flat-surface-only projects

Setup, Compatibility & Care

To set up your Mirka Iridium Sanding Triangle, align the 36-hole pattern on the abrasive sheet with the corresponding holes on your sander’s backing pad. Ensure the hook-and-loop system is centered for balanced vibration during use.

Compatibility

  • Sander Type: Works best with triangular orbital sanders featuring a 100x152x152mm backing pad.
  • Extraction: Highly recommended to be used with a central vacuum or portable dust extractor to maintain the 36-hole extraction efficacy.

Care Instructions

  • Avoid applying excessive downward pressure, as this may crush the abrasive grains and shorten the life of the sheet.
  • Store in a dry, temperature-controlled environment to preserve the adhesion properties of the backing.
  • Periodically inspect your backing pad for wear, as a damaged pad can cause uneven wear on the sanding triangle.
