Coating type impacts performance by affecting the roll's resistance to loading. Open-coat abrasives have spaces between grains to prevent clogging, while closed-coat abrasives are fully covered for maximum cutting action. The 3M STIKIT Refill features a special Fre-cut coating to resist loading, making it ideal for sanding between coats of finishes. Choose the right coating based on the material you're working with and your desired finish.
