Sanding Disc KLINGSPOR 225 mm PS19EK grit 40, self-adhesive, 50 pcs for polystyrene

Self-adhesive sanding discs KLINGSPOR PS19EK, 225 mm diameter, grit 40, pack of 50 are designed for sanding, shaping and rough finishing of polystyrene and similar soft foam materials. These 225 mm abrasive discs feature a coarse 40-grit surface that allows fast material removal and efficient contouring. The self-adhesive backing ensures secure attachment to compatible backing pads or holders, and the discs are suitable for use with orbital and random sanders that accept 225 mm abrasive discs.

Advantages

The coarse 40-grit abrasive provides rapid stock removal on soft foams and polystyrene while minimising clogging when used correctly. Self-adhesive backing enables quick fitting and replacement, reducing downtime during sanding tasks. The 225 mm diameter gives a wide contact area for consistent results across flat and contoured surfaces, and the discs are supplied in a pack of 50 for continuity of work without frequent reordering.

Suitable for

• Sanding and shaping polystyrene foam models and panels
• Removing excess material from insulation boards and decorative foam elements
• Rapid rough sanding before fine finishing or coating
• Use with compatible orbital or random sanders that accept 225 mm discs

Key specifications

• Diameter: 225 mm
• Abrasion grit: 40 (coarse)
• Backing type: self-adhesive
• Pack quantity: 50 discs
• Recommended material: polystyrene and similar soft foams
• Compatible with: orbital and random sanders designed for 225 mm discs

How to use

Attach the self-adhesive sanding disc firmly to a clean, compatible 225 mm backing pad or holder. Operate the sander at moderate speed and apply light, even pressure to avoid melting or indenting soft foam substrates. Move the sander in smooth passes along the workpiece to shape and remove material; check progress frequently and replace discs when abrasive performance declines.

Usage recommendations

For best results on polystyrene, use steady motion and avoid excessive heat build-up by limiting dwell time in one spot. When switching to finer finishes, follow with progressively higher grit abrasives and ensure dust is cleared between steps. Store discs flat in a dry environment to preserve adhesive backing.
