Sand Grain Filler and Refine

What happens here

After the wood grain filler has dried, the surface is sanded again using an orbital sander with appropriate grit sandpaper and a dust extraction system. This step removes any excess or uneven grain filler, further smoothing the surface until it is perfectly flat and free of any visible wood grain texture. An additional scraping step may be performed to clean up any stubborn dried residue. The video highlights that "MORE COATS ELIMINATES MORE GRAIN," indicating that repeating the application and sanding of grain filler might be necessary to achieve the desired level of smoothness.

Goal: Smooth the applied grain filler and achieve a flat surface
