Klingspor PS 33 CK Strips – Paper Backing, Self-Fastening for Paint, Varnish, Filler & Wood


The Klingspor PS 33 CK self-fastening strips are a durable, high-performance abrasive choice for sanding paint, varnish, filler, and wood surfaces. Designed for use with hook & loop orbital and delta sanders, these strips deliver a consistent cut and smooth finish while allowing for quick and easy abrasive changes.


Built with a robust C-weight paper backing, they offer enhanced strength and durability compared to lighter papers, while still providing enough flexibility to follow gentle contours. The aluminium oxide abrasive grain ensures a sharp and even cut, and the open coat structure reduces clogging—especially when sanding softer woods or coated materials.
