KLINGSPOR sanding sheet K.WŁÓKNINA NPA400 152×229 mm COARSE (MPN 350823)

KLINGSPOR sanding sheet K.WŁÓKNINA NPA400 152×229 mm COARSE is a non-woven abrasive designed for surface conditioning, deburring and cleaning of metal, wood and composite materials. The 152×229 mm sheet size fits common hand sanding blocks and compatible orbital and detail sanders. Its open-structure abrasive prevents rapid clogging, delivers uniform material removal and preserves the substrate geometry without aggressive cutting, making it suitable for controlled finishing tasks.

Advantages

This non-woven sanding sheet offers consistent abrasive performance with minimal surface gouging. The coarse grit provides effective removal of rust, paint residues and oxidation while maintaining an even finish. The open web structure promotes efficient dust clearance, extends product life and reduces the need for frequent replacement. The flexible sheet conforms to contours and edges, supporting work on irregular shapes and recessed areas.

Suitable for

• Surface conditioning and blending of welds on metal
• Deburring and edge finishing on metal and composites
• Removing rust, scale and old coatings
• Preparing surfaces prior to painting or sealing
• Cleaning and matting wooden surfaces before finishing

Key specifications

• Material: non-woven abrasive web
• Grit grade: coarse
• Sheet dimensions: 152 × 229 mm
• Open-structure construction for reduced clogging
• Flexible, conformable sheet for contours and edges

How to use

Use the sanding sheet by hand with a sanding block or with compatible finishing tools according to the tool manufacturer’s instructions. Apply steady, even pressure and work along or across the surface as needed to achieve uniform material removal. For machine use, secure the sheet to the appropriate holder and operate at recommended speeds to avoid overheating. Regularly inspect the sheet for wear and replace it when abrasive performance diminishes to maintain consistent results.

Usage recommendations

For best results on metal, start with the coarse sheet to remove heavy imperfections, then switch to finer non-woven grades if a smoother finish is required. Keep the work area ventilated and use appropriate personal protective equipment such as dust masks and eye protection when sanding.
