Klingspor KLINGSPOR sandpaper sheets 230×280 mm grit 400 (45251)

KLINGSPOR sandpaper sheets 230×280 mm grit 400 are designed for fine sanding and finishing tasks on wood, painted surfaces, primer coats and light metal deburring. The sheets measure 230 by 280 millimetres and feature P400 abrasive for achieving a smooth, even surface prior to painting or between finishing coats. They can be used for hand sanding or with platen-backed sanding tools where flat, controlled material removal is required.

Advantages

These sandpaper sheets provide a fine abrasive texture that removes minor imperfections and produces a uniform surface without aggressive cutting. The P400 grit is suited for delicate smoothing of fillers, leveling paint edges and preparing substrates for final coats. The sheet format offers versatility for both manual work and machine-assisted sanding on flat areas, allowing precise control over pressure and direction.

Suitable for

• Final sanding of wooden components before varnishing or lacquering
• Smoothing painted surfaces and primers between coats
• Light deburring and finishing of thin metal parts
• Refining filler and putty to an even finish
• Hand sanding and use with platen-backed sanding tools

Key specifications

• Dimensions: 230 × 280 mm
• Abrasion grade: P400 (fine grit)
• Format: flat sheets suitable for hand use or platen tools
• Recommended materials: wood, paint, primer, light metals, filler
• Primary application: fine finishing and surface preparation

How to use

Select the P400 sandpaper sheet and, if using a platen tool, secure the sheet to a flat backing to ensure even pressure distribution. For hand sanding, fold or hold the sheet flat and move with the grain on wood or with light, even strokes across painted surfaces. Apply gentle pressure and inspect the surface frequently to avoid over sanding. Replace the sheet if abrasive performance decreases or if clogging occurs.

Usage recommendations

For best results, start with coarser grit if substantial material removal is needed, then finish with the P400 sheets to achieve a smooth surface. Use light, consistent strokes and clean the surface of dust before applying paint or varnish to ensure proper adhesion and an even finish.
