3M Blue Net P220 Mesh Sanding Disc Roll 150 mm – 100 Pack

3M Blue Net P220 Mesh Sanding Disc Roll 150 mm – 100 Pack

3M Blue Net P220 Mesh Sanding Disc is an open-net abrasive disc developed for dry sanding and surface preparation. Featuring a 150 mm diameter and P220 grit, the product is supplied in rolls containing 100 discs. The Blue Net series combines abrasive cutting performance with an open mesh structure designed to support effective dust extraction.

The discs feature an engineered ceramic-mineral blend developed to support material removal and abrasive life. Their open-net construction allows sanding dust to pass through the abrasive surface into a compatible extraction system.

P220 Grit and Surface Preparation

P220 grit is suitable for fine surface refinement, intermediate sanding and preparation before subsequent finishing processes. It can be used after coarser abrasive grades to reduce sanding marks and produce a more uniform surface.

The Blue Net series can be used for sanding fillers, primers and painted surfaces. The P220 grade is suitable for intermediate sanding and surface refinement where the material and finishing process require this grit level.

Open-Net Construction and Dust Extraction

The open-net structure of 3M Blue Net abrasives allows sanding dust to pass through the disc surface into a suitable extraction system. Unlike conventional perforated sanding discs, the mesh design does not require alignment with a specific dust extraction hole pattern.

When used with compatible dust extraction equipment, the disc helps reduce dust accumulation on the working surface. Actual extraction performance depends on the sanding machine, backing pad and vacuum system.

Hook and Loop Attachment and Roll Packaging

The 150 mm discs feature a hook and loop attachment system for convenient installation and replacement on compatible sanding pads. The roll contains 100 discs for organised storage and repeated sanding operations.

The product is intended for dry sanding applications. Where a finer surface finish is required, subsequent sanding stages using higher grit numbers may be necessary.

Before use, ensure compatibility with the sanding equipment and backing pad. The permitted operating limits must be observed, and appropriate dust extraction and personal protective equipment should be selected according to the material being processed.
