Sanding primer surfacer: wet or dry?
Dry with mesh and dust extraction is faster and cleaner; wet is fine and dust-free. P320 to P400 for the surface, P600 before clear coat or light colours.

Questions about the products
Abrasives, accessories, a machine or a set – where do I start?
If you have a project ahead of you, the easiest start is a set: it contains the whole grit sequence from the first pass to the finished surface. If you already know what’s missing, filter by grit, size or machine. Accessories such as backing pads and interface pads depend on the diameter of your machine.
Which grit do I need?
Coarse (P24–P80) removes material, medium (P100–P180) shapes and levels, fine (P220–P400) smooths and prepares, very fine (P500–P1000) mattes paint, and ultra-fine (P1200 and up) is the finish before polishing. The grit guide explains every step; the abrasive finder tells you the grit for your project.
Will the discs fit my random orbital sander?
Yes, if the diameter (125 or 150 mm) and the hook-and-loop fixing match. The multi-hole pattern fits any hole layout. Every product page lists under “Technical details” which machines the product is made for.
Are there volume discounts?
Pack sizes are tiered: the bigger the pack, the lower the price per piece. Workshops, paint shops and businesses with regular demand get their own terms through KORNDEX Business – apply for a trade account and we’ll get back to you.
