Selecting Appropriate Grit Levels

What happens here

For general cabinet sanding, the presenter typically uses 220, 320, and 450 grit abrasives. For sanding grain fillers, he specifically uses 320 grit Filmtek. The Ekasilk Plus sponges are rated fine (around 220 grit), very fine (around 320 grit), and superfine (around 450 grit). The choice of grit depends on the stage of sanding and the desired smoothness. A chart detailing the exact grit equivalences is available on the provider's website. It is noted that the closed-cell Ekasilk sponges (5mm and 10mm) are denser and can be used on flat surfaces, though Filmtek is generally preferred for achieving the flattest possible surface for grain elimination.
