FAST-CUTTING SILICON CARBIDE GRAIN - compared with aluminum oxide, silicon carbide grain is sharper and harder, producing faster cut rates, less sanding time, and better finish quality. 1/2" THICK FLEXIBLE FOAM - the ultra low-density 1/2" thick open cell polyurethane foam maximizes flexibility and allows sanding of detailed contours and complex shapes without burning through. Ideal for cabinetry, furniture refinishing, paint work, and fine finish work. WET/DRY COMPATIBLE - These sanding sponges are wet/dry compatible and ideal for sanding all surfaces, including bare wood, latex or oil paint, stained wood, autobody, metal, epoxy, gelcoat, plaster, etc. Rinse, reuse, and keep working!

These pads use a 1/2" low-density open-cell foam that conforms easily to curves, profiles, and moldings without cutting through edges or high spots. Ideal for prepping delicate surfaces for clear coats or topcoat smoothing, the premium silicon carbide abrasive cuts cleanly and evenly across a variety of surfaces. Hook & loop backing allows quick pad changes, and the foam construction supports both wet and dry use for versatile performance.
