FAQs

Do I need a specific hole pattern for these discs?

No, the SiaNet discs use a mesh design that extracts dust through the entire surface, eliminating the need to align holes.

Can these be used for wet sanding?

These discs are primarily designed for dry sanding applications.

What tools are these compatible with?

They are compatible with any standard 150mm (6-inch) random orbital sander equipped with a hook-and-loop pad.

How many discs are in one pack?

Each pack contains 50 sanding discs.

Is P240 considered a coarse or fine grit?

P240 is considered a fine grit, ideal for sanding between coats or final surface preparation before finishing.

Troubleshooting

Disc is slipping on the backing pad

Clean the hook-and-loop pad of the sander to remove buildup and ensure the disc is pressed firmly onto the pad.

Poor dust extraction

Ensure your sander's dust bag is emptied or your vacuum hose is not obstructed; clean the mesh if it is saturated with resinous dust.

Pros and Cons

Pros

  • Superior dust extraction reduces cleanup time
  • Net structure prevents abrasive loading and clogging
  • Excellent finish consistency with P240 grit
  • Durable construction offers longer lifespan than paper discs

Cons

  • Requires a high-quality vacuum system for maximum dust collection
  • Mesh material may tear if used on sharp protruding edges
  • Higher initial cost compared to standard paper sanding discs

Setup, Compatibility & Care

To set up these discs, simply align the 150mm disc with the hook-and-loop backing pad of your orbital sander. Because there is no fixed hole pattern, you do not need to worry about aligning dust extraction holes. For optimal care, store the discs in a cool, dry environment to maintain the integrity of the abrasive grains and the hook-and-loop backing. After use, you can gently tap or blow the disc with compressed air to clear trapped particles, which helps prolong the life of the disc before needing a replacement.
