Abrasive Hook-and-Loop Disc KLINGSPOR 225 mm PS19EK grit 36, pack 50 for polystyrene

KLINGSPOR abrasive hook-and-loop disc PS19EK, 225 mm diameter, grit 36, pack of 50 is designed for rapid material removal on polystyrene and other soft foam materials. The coarse grit and open coating deliver efficient sanding performance while the PS19EK hook-and-loop backing enables fast attachment and release on compatible sanding pads. These discs are intended for use with manual and powered orbital sanders that accept a 225 mm PS19EK backing plate.

Advantages

The coarse 36 grit abrasive provides aggressive material removal for shaping and leveling polystyrene surfaces without excessive clogging. The hook-and-loop PS19EK backing ensures quick disc changes and stable fixation during sanding. The discs are supplied in a pack of 50, providing consistent performance and reducing downtime for frequent jobs. The 225 mm diameter offers a large working area for faster coverage of broad surfaces.

Suitable for

• Sanding and shaping polystyrene models and panels
• Removing excess foam and trimming soft insulating materials
• Prepping foam substrates before adhesive application or painting
• Coarse sanding with orbital sanders using PS19EK backing plates

Key specifications

• Diameter: 225 mm
• Abrasive grit: 36 (coarse)
• Backing type: hook-and-loop (PS19EK)
• Intended material: polystyrene and similar soft foams
• Pack quantity: 50 discs

How to use

Attach the disc to a compatible 225 mm PS19EK hook-and-loop backing pad on a manual or powered orbital sander. Start sanding at low to moderate speed to avoid excessive heat build-up; increase pressure or speed only if the disc and substrate remain stable. Maintain a consistent, even motion across the workpiece to prevent gouging. Replace the disc when the abrasive becomes worn or clogged to preserve sanding efficiency.

Usage recommendations

Use protective equipment such as dust masks and eye protection when sanding polystyrene. For best results, test on a scrap piece of material to determine optimal sander speed and pressure. Avoid prolonged high-speed contact to reduce the risk of melting or deforming soft foam surfaces.
