Sandpaper Disc GEKO G78688 225 mm P240 with Holes, for Orbital Sanders (pack sizes vary)

GEKO sandpaper disc G78688 is a 225 mm abrasive disc with P240 grit and dust extraction holes designed for orbital and rotary sanders. It delivers fine sanding performance on wood, paint and filler, enabling smooth surface preparation and finishing. The disc uses a hook-and-loop backing fit for standard 225 mm sanding pads and is offered in several pack sizes to suit different project scales.

Advantages

The P240 grit provides a fine abrasive action that produces a uniform, low-scratch finish on painted surfaces, veneers and filler. Integrated dust extraction holes improve dust removal when used with compatible sanders, helping to maintain visibility of the work area and reduce airborne particles. The hook-and-loop backing allows quick attachment and replacement on 225 mm backing pads, supporting efficient workflow during renovation and finishing tasks.

Suitable for

• Fine sanding of wooden surfaces before finishing
• Sanding between paint coats and for paint removal of minor imperfections
• Smoothing putty, filler and joint compounds
• Light surface preparation prior to varnishing or staining

Key specifications

• Diameter: 225 mm
• Abrasion grade: P240 (fine)
• Attachment type: hook-and-loop (velcro) compatible with 225 mm backing pads
• Dust extraction: pre-cut holes for use with vacuum-equipped sanders
• Intended materials: wood, painted surfaces, fillers and similar substrates

How to use

Fit the disc onto a compatible 225 mm hook-and-loop backing pad, ensuring the holes align with the sander’s dust extraction pattern. Start sanding at low speed to check abrasive action and increase speed gradually if needed, keeping the sander moving to avoid creating grooves. Replace the disc when abrasive performance diminishes or when the surface finish no longer improves. When sanding paint or filler, use light, even passes and inspect the surface frequently to prevent over-sanding.

Usage recommendations

Use with an orbital or rotary sander equipped with a dust extraction system for best results. For best surface quality on delicate or thin veneers, test on a scrap piece first and consider finishing with a finer abrasive if required. Store discs flat in a dry environment to maintain abrasive integrity.
