Klingspor PS 33 C Sheets – Paper Backing for Paint, Varnish, Filler & Wood


The Klingspor PS 33 C abrasive sheets are a durable, high-performance sanding solution for preparing and finishing paint, varnish, filler, and wood surfaces. Designed for hand sanding or use with sanding blocks, they provide a consistent cut and smooth finish across a variety of substrates.


Featuring a medium-weight C-weight paper backing, these sheets offer a balance between flexibility and strength, making them suitable for both flat and slightly contoured surfaces.
