Abrasives and Polishing Products for the Perfect Instrument Finish

Abrasives and polishing products are essential companions in violin making – from the first sanding of the wood to the final gloss of the varnish. In this category, you’ll find a carefully selected range of high-quality items: sandpaper in various grits for precise work, flexible sanding sponges for hard-to-reach areas, fine polishing powders for smoothing and matting surfaces, the trusted JOHA® Sanding and Polishing Paste for even, finely controlled surface preparation, and JOHA® Polish and Care Gloss for gentle polishing and a deep, natural shine.

All materials are specially designed for the delicate surfaces of string instruments and allow for controlled, professional handling. Whether you're performing an intermediate sanding between varnish layers or the final polishing step – our abrasives and polishing agents give your instrument a flawless finish – both visually and to the touch.
