Klingspor self-adhesive sanding disc PS 33 BK / PS 33 CK 150 mm grit 150, pack 100

Klingspor self-adhesive sanding disc PS 33 BK / PS 33 CK 150 mm in P150 grit is a versatile abrasive designed for surface sanding and light finishing. The 150 mm diameter and P150 abrasive grain provide consistent material removal and a fine-to-medium finish on wood, painted and varnished surfaces, and soft metals. The discs come with a self-adhesive backing suitable for attachment to compatible disc holders and many hook-and-loop systems, enabling both machine and manual use. Packaged as a set of 100, these discs suit repeated tasks in woodworking, renovation and auto-body preparation.

Advantages

The abrasive combines uniform grit distribution with a stable backing that ensures even sanding and reduced clogging. The self-adhesive backing allows quick attachment and replacement on sanding plates and holders, saving time during repetitive operations. The P150 grit achieves a balanced compromise between material removal rate and surface smoothness, making it effective for intermediate sanding and preparing surfaces for further finishing or painting.

Suitable for

• Sanding and intermediate finishing of solid wood and wood-based panels
• Removal of old paint and light surface defects on painted or varnished surfaces
• Fine sanding of soft metals and metal primers before painting
• Orbital sander use and manual sanding with disc holders
• Batch tasks in renovation, carpentry shops and auto-body prep

How to use

Ensure the sanding plate or holder is clean and free of debris before applying a disc. Peel the backing liner and press the disc firmly onto the sander pad to secure adhesion. Use the appropriate orbital sander speed and light, even pressure to avoid overheating the abrasive and the workpiece. For hand sanding, mount the disc on a compatible holder and sand using steady, overlapping strokes. Replace the disc when the abrasive wears down or becomes clogged to maintain consistent surface quality.

Usage recommendations

For best results, test the P150 disc on a scrap piece to confirm the finish meets requirements. Use dust extraction where possible to reduce clogging and extend disc life. When preparing substrates for final coatings, follow progressive grit steps as needed — for example, moving from coarser to P150, then to finer grits for a smoother final surface.
