KLINGSPOR Sandpaper PS 33 CK 150 grit Velcro backing for power sanders and hand sanding

KLINGSPOR Sandpaper PS 33 CK 150 grit with Velcro backing is an abrasive disc designed for efficient sanding of wood, paint and primer layers. The hook-and-loop backing allows fast attachment and removal on compatible random orbital and hook-and-loop power sanders, as well as for manual sanding with a pad. The 150 grit abrasive offers medium-fine cut for smoothing surfaces, removing imperfections and preparing substrates for finishing coats while maintaining consistent material removal and predictable surface texture.

Advantages

The Velcro backing ensures quick, secure disc changes without adhesive, reducing downtime during work. The abrasive grain distribution provides even sanding performance and extended life compared with untreated papers, while the paper backing maintains stability during both machine and hand use. The 150 grit grade balances cutting rate and surface refinement, making it suitable for a range of preparation tasks prior to painting or sealing.

Suitable for

• Sanding wooden furniture and joinery
• Removing old paint or primer layers
• Surface preparation before lacquering or staining
• Intermediate sanding between coats
• Hand-sanding in confined areas with a sanding pad

Key specifications

• Abrasion grit: 150 (medium-fine)
• Backing type: hook-and-loop (Velcro) for quick attachment
• Compatible use: random orbital sanders, hook-and-loop sanders, manual sanding pads
• Recommended materials: wood, paint, primer
• Paper backing for dimensional stability during sanding

How to use

Attach the sandpaper disc to a clean hook-and-loop backing pad on the sander, ensuring it is centered to prevent vibration. For power sanding, operate the tool at the manufacturer’s recommended speed and apply moderate, even pressure; allow the abrasive to remove material gradually rather than forcing the disc into the surface. For hand use, adhere the disc to a sanding pad and move it along the grain on wood or in slow, controlled passes on painted surfaces. Replace the disc when wear reduces cutting efficiency or when the abrasive surface becomes clogged.

Usage recommendations

Use dust extraction or local ventilation when sanding painted surfaces. Test on a small area before full application to confirm the grit achieves the desired finish. Store discs in a dry environment away from direct sunlight to preserve adhesive performance of the backing and the paper stability.
