Fill Imperfections and Re-sand Countertop

What happens here

After joining the panels, any visible pocket holes or small gaps are filled with wood filler. The filler is applied with a putty knife, ensuring it is pressed firmly into the imperfections. Once the filler dries, the entire countertop surface is sanded again with an orbital sander (Festool orbital sander) and 120-grit sandpaper to achieve a perfectly smooth and seamless finish, preparing it for the final coating.

Goal: Any remaining screw holes or minor imperfections on the countertop are filled with wood filler, which is then sanded flush to create a flawless surface.
